You may bump in to five or ten of them during this workshop, but the rest could remain utterly unknown to you. That's a shame, because there are loads of software out there, and if you like to scavenge, or if you desperately need a routine to solve a particular problem, you may be missing a useful source of help. I'd like to explain the system we use when installing software. Once you're used to the pattern, you will be able to investigate new packages easily. In particular, I want to emphasize how easy it is for you to get your hands on the actual source code of most of our libraries. An overview of some of the more useful groups of software follows. I'll make some claims about the various big mathematical packages like IMSL, and then point out the many specialized packages that deal very extensively with a small topic. The SCILIB mathematical library is of special importance, because it is a "built in" piece of software which is highly optimized. The routines in SCILIB are almost as much part of Cray FORTRAN as "SQRT". There are good reasons to see whether you can use SCILIB for some of your work. This still leaves most of our packages unmentioned. I hope you will browse around and investigate what else we have. But rather than list more of our installed packages, I would like to finish by telling you about some treasure troves of software that we ourselves haven't finished plundering. This includes the TOMS algorithms, and the NCAR local library, as well as various electronic software distribution services. We've tried, when installing software, to follow a scheme which makes your work easier. We've done this by putting all software in the same place, writing help files and documents with standard names, making examples of use available, and making the source code itself available when possible. To get the most out of our software, it's important that you know how to take advantage of this setup. Some of the following information is available online in the document "GUIDELINES.DOC". 2.0 Online help: Online help contains QUICK and BRIEF reminders about commands or software. Help commands are "MAN" (UNICOS, ULTRIX and VMS) and "HELP" (VMS only). Online help is documented in "ONLINE.DOC". 2.1 Help on system commands via MAN The MAN command was intended for help on operating system level commands. The UNICOS "MAN" command describes UNICOS commands you will use every time you log in, such as CF77, LS and CD. The information has been written and installed by Cray Research. To find out about the CF77 compiler, for instance, type: man cf77 MAN information is very compressed. It's hard to read on the screen. You'll want to redirect the output to a file and read it at your leisure, using a command like man cf77 > myfile.txt or, on VMS, man -o myfile.txt cf77 2.2 Help on PSC software via MAN The PSC has added information about local software to the MAN system. On any PSC machine, typing "man" followed by the name of a program will give you brief help on the program. For example, you could type: man scilib The MAN program will then print out, one page at a time, a short explanation of the purpose of the given program, followed by a list of documentation, examples, source code, usage, and references. For a list of all PSC software, type man software For a list of current software news, type man journal On VMS only, you may also use the HELP or PSCHELP command to get the same information. 3.0 Online Documents: To get full information on software, you need the document system. All documents are available to PSC users in AFS, CFS and on VMS. Non-PSC users can easily get copies of the documents via anonymous FTP. Most documents have filenames ending in "DOC", but large ones end in "BIG". A list of all documents is available in "DOCUMENTS.DOC". 3.1 ULTRIX and CMVAX access to documents in AFS All PSC documents are available to users of CMVAX, the UNIX front ends, and local workstations via AFS (Andrew File System). With some exceptions, AFS looks a lot like a standard UNIX file system, to which standard UNIX commands may be applied. The location of the documents in AFS is the directory "/usr/local/doc". To get a list of all the documents in AFS, you could type ls /usr/local/doc or for a more detailed listing of a particular file: ls -l /usr/local/doc/bcslib.doc To type out a document one page at a time: more /usr/local/doc/bcslib.doc To search a document for the string "differential": grep -i differential /usr/local/doc/odepack.doc or to see if ANY document has the string "differential": grep -i differential /usr/local/doc/* To use an editor to browse through the file, you might say: ed /usr/local/doc/pdecol.doc or edit /usr/local/doc/pdecol.doc or vi /usr/local/doc/pdecol.doc or emacs /usr/local/doc/pdecol.doc To copy a document to your home directory: cp /usr/local/doc/odepack.doc odepack.doc You can actually change your working directory to that area, with the command cd /usr/local/doc in which case, all of the above commands can drop the "/usr/local/doc" prefix. 3.2 UNICOS access to documents in CFS All PSC documents are available to UNICOS users through CFS. To do anything with a file in CFS, it must be copied out of CFS into your directory space. Once it is copied out, you can use "MORE" or "GREP" or an editor to search through the file. Unfortunately, you CAN'T search through the whole document system as it lies in CFS. To get a list of all the documents in CFS, you could type cfs list /usr/local/doc 3.3 VMS access to documents in the PSCDOC: directory All PSC documents are available in a single VMS directory named PSCDOC. Some operations can be carried out without copying the file from PSCDOC. To get a list of all the documents, you could type $ DIR PSCDOC or, perhaps, for just the documents with "last name" of "DOC", $ DIR PSCDOC:*.DOC To type out a document one page at a time: $ TYPE/PAGE PSCDOC:BCSLIB.DOC To search all the documents for the string "differential": $ SEARCH PSCDOC:*.DOC "differential" or $ SEARCH PSCDOC:*.DOC,*.BIG "differential" In some cases, you may be able to use an editor to browse the file, with a command like: $ EDIT/READ PSCDOC:CALMATH.DOC However, you may find it easier to copy the file to your current directory first: $ COPY PSCDOC:DASSL.DOC * This copy can be edited, deleted, or otherwise mutilated as you wish. 4.0 The EXAMPLES Directories: The PSC has set up sample input and result files for most software. These can be used to learn how a program works, to test a program without knowing much about it, or as a "starter" file you can convert to solve a problem you're interested int. The system is fully written up in the document EXAMPLES.DOC. 4.1 CMVAX and ULTRIX access to examples in AFS If you are logged in to CMVAX, the ULTRIX front ends, or an ULTRIX workstation at the PSC, you can start the EXAMPLES program by typing: examples The typical use of EXAMPLES is to display or copy some example files for a particular package and machine. The main menu will ask you to specify a machine (cm2, ultrix, vms or ymp) and then a package (bcslib, odepack, etc). Once this information is specified, you will see a list of the files available in that directory, and a secondary menu will be displayed, allowing you to type or copy them. 4.2 UNICOS access to examples in CFS On UNICOS, the examples files are available through CFS. The CFS examples are all subdirectories of the CFS directory /usr/local/examples. The same BCSLIB files are available in the CFS directory /usr/local/examples/bcslib You can list them by typing: cfs list /usr/local/examples/bcslib and then, to retrieve, say, bcsprb.f, type: cfs get /usr/local/examples/bcslib/bcsprb.f 4.3 VMS access to examples in DOC$ROOT1:[EXAMPLES] On VMS, the examples area is the directory DOC$ROOT1:[EXAMPLES]. This area is divided into two subdirectories, DOC$ROOT1:[EXAMPLES.VMS] and DOC$ROOT1:[EXAMPLES.YMP]. Examples for a given piece of software will then be a subdirectory of one of these areas. The BCSLIB examples for the YMP are in the subdirectory DOC$ROOT1:[EXAMPLES.BCSLIB], for instance, and you could copy the files in that directory by typing $ COPY DOC$ROOT1:[EXAMPLES.YMP.BCSLIB]*.* * However, we recommend that you type $ SETUP EXAMPLES and then use the command "GRAB" to copy the files you want, or "EXAMPLES" to browse. 5.0 Access to Source code: The source code for most of the programs installed at the PSC is available for examination by, or distribution to our users. With some exceptions, you are free to copy such source code, print it, modify it, take it to other machines and so on. The exceptions are the proprietary programs, such as IMSL and NAG, and other programs whose authors have specifically requested that the source code not be distributed. Source code is available in CFS only. There is no direct way to get source code on VMS, except by sending an NQS job to the Cray. There is no direct way to get source code through anonymous FTP. A complete discussion of source code availability is in SOURCE.DOC. That document lists all the CFS source code directories, and their contents. The CFS source code directories are subdirectories of /usr/local/src/bin where source code for executables is kept, and /usr/local/src/lib where source code for libraries is kept. For example, the source code for the executable program KIVA2 is stored in the CFS directory /usr/local/src/bin/kiva2 while the source for the library program CHRPAK is in the CFS directory /usr/local/src/lib/chrpak Here, we will just make a few general remarks using CHRPAK as the example: To get a list of the files contained in the CHRPAK CFS source code directory: cfs list /usr/local/src/lib/chrpak The CHRPAK CFS source code directory includes the following files: chrpak.f The source code for the main portion of CHRPAK. chrpakuni.f The source code for a UNICOS-specific portion of CHRPAK. chrpakvms.f The source code for a VMS-specific portion of CHRPAK. chrpak.com VMS COM file which compiles, installs CHRPAK at PSC. makefile UNICOS makefile which compiles, installs CHRPAK at PSC. To copy, for instance, chrpak.f from the CHRPAK source code directory, type: cfs get /usr/local/src/lib/chrpak/chrpak.f If you were going to install CHRPAK on another VMS machine, you would need chrpak.f, chrpakvms.f and chrpak.com. Similarly, to install CHRPAK on another Cray, you would need chrpak.f, chrpakuni.f, and makefile. If you were going to install it on some other operating system entirely, you should copy all the source code files and look them over. 6.0 How to use Software: Many programs are available on all systems, ULTRIX, VMS and UNICOS. Most VMS programs, whether libraries or executables, are stored in the directory PSC$LIB. Executable programs end with an extension of ".EXE". They may be run using the RUN command. For example, the LINPACK benchmark program is PSC$LIB:LBENCH.EXE, and can be run by typing $ RUN PSC$LIB:LBENCH Library files will generally have the extension ".OLB" and are used in connection with a compiled user calling program. For example, there is an ODE solving package called ODEPACK, whose compiled code is available in the file PSC$LIB:ODEPACK.OLB. To use ODEPACK, a program must be written which dimensions arrays, initializes data, and calls one or more of the subroutines in ODEPACK. The compilation of the user calling program, which we'll assume is called "MYPROG.FOR", would be done by $ FORTRAN MYPROG.FOR Now the compiled ODEPACK routines must be added to the user program to make an executable: $ LINK MYPROG.OBJ,PSC$LIB:ODEPACK/LIB and the executable can be run by typing: $ RUN MYPROG On UNICOS, executables are stored in /usr/local/bin, and generally have no special extension. They are run simply by issuing their name, and you don't even need to specify the "/usr/local/bin" information. Thus, KIVA2 would be run by typing kiva2 UNICOS object library files are in /usr/local/lib. The files have "lib" put in front of its name, and an extension of ".a". Usually, ".a" files will be used this way: cf77 myprog.f -lodepack The document "SOFTWARE.DOC" contains a list of all the software installed at the PSC. It lists many topics, and the software that can solve problems in those areas. ULTRIX programs are stored in the same places, and used in the same way, as the UNICOS programs. The one exception is that the FORTRAN compiler is called "f77" rather than "cf77". 7.0 Mathematical Libraries If you're writing programs regularly, it's a good idea to choose a general mathematical library to rely on. Such libraries CAN provide accurate, reliable, portable software. Moreover, a library may be optimized for a given computer, relieving you of the necessity of dealing with low level details. Library software is available for many of the following problems: Differential equations y'=f(x) Eigenvalues and eigenvectors, A*x=lambda*x Fourier transforms and time series analysis Interpolation, approximation, data smoothing Least squares solutions of A*x=b, data fitting Linear systems: solution of A*x=b, matrix factors, inverse or determinant Minimization of a scalar function f(x) of one or many variables Nonlinear equation solution, f(x)=0 for one or many variables and equations. Quadrature or Approximate Integration Special Functions (Bessel, Error, Gamma) Statistics and Probability (Regression, Correlation, Variance) Some general libraries at the PSC include: BCSLIB, CALMATH, CMLIB, HARWELL, IMSL11, MATHLIB, NAG13, RECIPES, SLATEC31, Very brief comments about some of the libraries follow: BCSLIB - Boeing Computer Services library Outstanding vectorization on Cray YMP. Good documentation, available from vendor. Some online. All routine names being with H. An error flag IER is always used. IMSL11 - International Mathematics and Statistics Library Very widespread package, available even on PC's. Excellent documentation, available for $15 at some bookstores. Interactive documentation program available. NAG13 - Numerical Algorithms Group British origin. Good algorithms, more aggressive optimization than other libraries. Excellent documentation, not widely available. Interactive documentation program available. Routine names begin with a letter, then 2 digit number. SLATEC31 - Sandia/Livermore/Air Force Technical Exchange Collection National Laboratory software, source code freely available. Swallowed whole many famous packages (LINPACK, EISPACK, MINPACK, others). Interactive documentation, but NO hardcopy available! 8.0 Vendor Supplied Scientific Libraries Vendors simplify the use of supercomputers by providing a scientific library. The library can carry out common mathematical tasks for the user, while accessing the computer in a highly optimized way. Such a library allows beginning users to achieve high performance with little training. There are two such libraries available at the PSC: SCILIB for the Cray YMP, CMSSL for the Connection Machine. 8.1 SCILIB SCILIB is a built in library provided by Cray Research, Inc. The routines in SCILIB were intended to supply a solid base of popular routines that had been well optimized for the Cray. It was NOT the intent of CRI to supply a full mathematical library. SCILIB includes three linear algebra packages: BLAS Basic Linear Algebra Subprograms. EISPACK The standard eigenvalue package. LAPACK New linear algebra library, superior to LINPACK and EISPACK. LINPACK The standard linear algebra package. Aside from these packages that SCILIB swallowed wholesale, there are also: Fast Fourier Transforms Matrix-vector and matrix-matrix multiplication "Recursion" or "Recurrence" algorithms Vector search Sorting Vectorized random number generation VAX/Cray binary data conversion CHARACTER string manipulations Timing routines: real time, CPU time, clock cycles SCILIB is partially written in CAL, and optimized for the Cray. This means that SCILIB can be faster than a user program written in FORTRAN because a CAL program can specify that certain operations be done in a certain order, that certain vectors be kept in a local register, and so on. For example, to compute the matrix-vector product x=A*y, the following FORTRAN code might be used: DO 10 J=1,N DO 20 I=1,N X(I)=X(I)+A(I,J)*Y(J) 20 CONTINUE 10 CONTINUE which will read and write each element of X N times. If a SCILIB routine (MXVA in this case) is used, the Cray can use registers and other tricks to cut down on the I/O while getting the same result more quickly. SCILIB is fully documented in SCILIB.BIG. For your convenience, we've installed a FORTRAN version of SCILIB on ULTRIX and VMS. This version has been extended at the PSC to include more of the UNICOS SCILIB routines. 8.2 CMSSL CMSSL is the Connection Machine Scientific Software Library. This library is supplied by Thinking Machines Corporation, the vendor of the Connection Machine. It is a library of subroutines for solving certain common mathematical problems. It contains well written algorithms for solving mathematical problems that are ideally suited for treatment on the Connection Machine. The algorithms have been carefully implemented for superior performance. CMSSL version 2.2 now supports both the slicewise and Paris models of the CM Fortran compiler. For more information on the slicewise model, see SLICEWISE.DOC. CMSSL can be linked with code written in C*, C/Paris, CM Fortran, Fortran/Paris, *Lisp or Lisp/Paris. CMSSL offers routines for the following operations: Broadcast of data from CM arrays to all processors; Fast Fourier transforms (powers of 2 only); Histogramming (data counting) routines; Linear equation solution, square matrix A, A*x=b: for a dense matrix A, using Gauss-Jordan or QR algorithm; for a triangular matrix A; for a tridiagonal matrix A, using cyclic reduction; Matrix inversion; Matrix-matrix and matrix-vector multiplication, A*B, A*x, or x*A; QR factorization and solution of rectangular linear systems; Random number generation (uniform); Sparse matrix vector product; For details, see the document CMSSL.DOC. 9.0 Special purpose software Some scientific and engineering fields are well enough understood that executable programs are available to solve a wide range of problems. The user has only to prepare a data file describing the particular problem. This is quite a different approach than that required when building a program by calling library routines. 9.1 Engineering Programs Sometimes called "finite element" programs, this category includes fluid flow and structural mechanics. Well known programs available at the PSC include the structural programs ABAQUS, ANSYS, BOPACE and SAP4, the fluid programs FIDAP and FLOW3D, the electronic circuit program SPICE, and the internal combustion modeler KIVA. Moreover, the PSC has the whole series of dynamics codes from Livermore labs, including DYNA and NIKE. Versions of these programs were used, for instance, to model the deformation of aluminum cans under a crushing force by users from ALCOA. Some of these programs may not be used without permission. In that case, you must send mail to REMARKS requesting access. 9.2 Computational Chemistry The one program that accounts for the most usage at the PSC is the "Gaussian" quantum chemistry program. This is an "ab initio" package that computes the properties of atoms and molecules from basic theory. Gaussian is maintained at the PSC by Doug Fox, one of the members of the team that developed the program. The PSC sponsors workshops on Gaussian and on computational chemistry. Gaussian is documented in "GAUS90.DOC". Other packages available include AMBER, AMPAC, CADPAC40, CHARMM, GAMESS90, MOPAC, and POLYRATE. 9.3 Biomedical software The PSC has received a grant from the NIH to foster biomedical supercomputing. To that end, the PSC has collected many databases, and installed or adapted or created software to query those databases, to do sequence alignment and biomedical modeling. The databases available include GenBank and EMBL. Software includes RNAFOLD and RANFOLD, for structure prediction, SEQA/SEQH/SEQHP sequence alignment programs, and the XPLOR modeling program. The MAXSEGS sequence alignment program is available on both the Cray and the Connection machine. The PSC has a staff of three full time biomedical specialists who work with users and develop software. 10.0 Exercises Most of these exercises may be carried out on the Cray YMP, the VAX/VMS system, or the ULTRIX front end machines. If you are using the Cray, you will have to get documents out of CFS before reading them. You should not send mail, since you can't receive it. If you are using the VAX, you should probably run programs by submitting them to the Cray over the station. 10.1 Online help A) Get online help for the PSC installed program ANSYS, using MAN on UNICOS or ULTRIX, or HELP or MAN on VMS. B) Repeat this test, using redirection on UNICOS or ULTRIX, or the "HELP/OUTPUT" or "MAN -O" commands on VMS, to store the information into a file. C) Get online help for the UNICOS or ULTRIX system command CD, using MAN. If you are on VMS, try getting help on CD using the HELP command. You won't get it. But you will get something else. What's the problem? On VMS, try again using the MAN command. 10.2 Online documents A) If you are using ULTRIX or VMS, search all documents whose first name begins with "g" for the string "external". This is something you can't easily do on UNICOS! (Because the files are in CFS). B) Then search the document CHRPAK.DOC for the string "reverse". On UNICOS, you will have to retrieve the file from CFS first, and you should include the switch "-i" in the GREP command. C) Find, in the document CHRPAK.DOC, the documentation for subroutine CHRREV, which explains the arguments for the routine. Save these lines to a file. On VMS, you may run into a file protection problem if you type "EDIT PSCDOC:CHRPAK.DOC". Use "EDIT/READ" instead. 10.3 Examples A) Get the YMP example job for BAILEY: On VMS, you will need to type "SETUP EXAMPLES" first. Get the YMP examples. The file you are interested in is ""BAILPRB.JOB". On UNICOS, you will need to retrieve each file one at a time out of CFS. Just get "bailprb.job". On ULTRIX, just type "examples", and specify the machine (YMP) and package. You want to copy "bailprb.job". B) Run the BAILEY example: On VMS, you can type "CRAY" to setup the connection between the Cray and the VAX, insert the correct information in the first line of "BAILPRB.JOB", type "CSUBMIT BAILPRB" The job will be sent to the Cray, and you will be notified by a message on the screen when the results come back in the file "BAILPRB.CPR". On UNICOS, to run in batch mode, type "qsub bailprb.job". Your job results will come back in two files, bailprb.e1234 and bailprb.o1234 ("1234" will actually be some other random four digit number!). The second file contains the interesting output! On ULTRIX, copy the file "bailprb.job" from the examples directory for the YMP. You will need to use the PSCSUB command to submit jobs. Please read the online documentation for PSCSUB, since you will need to set up special permission files on ULTRIX and UNICOS. Once you've done that, send the job to the Cray using the PSCSUB command "pscsub bailprb.job". 10.4 Source code A) Get the source code for the C LINPACK benchmark code "LBENCHC". If you do not want to touch a C program, then carry out this exercise using the FORTRAN version of the LINPACK benchmark code, "LBENCH". Use the MAN program to find out where the source code is. If you are on VMS, you will need to submit a job to the Cray to get the source code. If you are on ULTRIX, you will have to use the TELNET program to log in to the YMP, and the FTP program to send the file back to ULTRIX. B) Compile and run the source code using these commands: On UNICOS or ULTRIX: cc lbenchc.c a.out or on VMS: $ CC/NOLIST LBENCHC.C $ SETUP C $ LINK LBENCHC $ RUN LBENCHC 10.5 Using PSC executable programs A) Run the FORTRAN LINPACK benchmark programs. On VMS, you can run the local version, or submit a station job to run the Cray version. On ULTRIX, you'll have to run the local version. On UNICOS, there are two versions: LBENCH and LBENCHSCI. LBENCH uses FORTRAN versions of LINPACK routines, but LBENCHSCI uses the Cray SCILIB versions. Notice the difference in speed! B) Try to preserve the output of LBENCH in a file: On UNICOS or ULTRIX, use redirection: lbench > lbench.out On VMS, try using one of these assignments: $ ASSIGN/USER LBENCH.OUT SYS$OUTPUT $ RUN PSC$LIB:LBENCH 10.6 Using PSC library programs: A) Compile this program, link it with CHRPAK, and run it: PROGRAM TEST CHARACTER STRING*30 STRING='A man, a plan, a canal - Panama!' WRITE(*,'(1X,A30)')STRING CALL CHRREV(STRING,0) WRITE(*,'(1X,A30)')STRING STOP END B) Take a look at what's in the compiled CHRPAK library: On UNICOS or ULTRIX, use the "ar" command to get a list of what's in the library file "/usr/local/lib/libchrpak.a": ar t /usr/local/lib/libchrpak.a On VMS, use the command "LIBRARY/LIST PSC$LIB:CHRPAK.OLB" command to get a list of what's in the CHRPAK library. 10.7 Using mathematical libraries This exercise will help you get a feeling for the strengths and personalities of each of the PSC's mathematical libraries. For this exercise, we suggest you compare the libraries BCSLIB, IMSL11, NAG13 and SLATEC31. You don't have to answer the questions below, but at least write down any comments suggested by the questions. You are a researcher with a set of 11 pairs of X, Y data values representing the value of a function at the points 0, 1, 2, ... 10. You need a subroutine that will interpolate this function so that you can request interpolated values at, say 3.7 or 9.6. A) For each library, does it take more than a minute to find the name of a subroutine to do this? (Use the online documentation or the documentation programs). HOW FAST DID I FIND THE SUBROUTINE? BCSLIB __________________________________________________ IMSL11 __________________________________________________ NAG13 __________________________________________________ SLATEC31 __________________________________________________ B) Assuming that you found a routine to do the job, glance over the documentation briefly. How many of the arguments do you think you understand? How many are confusing? Were there any arguments where you weren't sure if they were input or output? Were there any arguments whose type wasn't clear (REAL or INTEGER or COMPLEX or ...)? HOW EASY WAS THE DOCUMENTATION TO UNDERSTAND? BCSLIB __________________________________________________ IMSL11 __________________________________________________ NAG13 __________________________________________________ SLATEC31 __________________________________________________ C) Prepare a simple program to test the routines you found. Use as data the values X(I)=I, and Y(I)=X(I)**2 for I=0 to 10. Request that the program return the interpolated value of Y at X=2.5, which should be 6.25 if you are using quadratic or cubic interpolation. How hard was it to prepare this routine for each library? If you alter the data so that X(1)=X(2), this should cause an error. Does the program complain? Is the error message understandable? HOW HARD WAS IT TO WRITE A SIMPLE CALLING PROGRAM?
