Software Available on
VT ARC Sun Systems

This page lists software which is currently available for your use on the VT ARC Sun Systems (Styx and Dante); for a listing of additional research software available at Virginia Tech, see:

Application Software

MATLAB

provides an environment and collection of tools for visualization, computation, and mathematical analysis.

To invoke MATLAB interactively, enter:

/software/matlab/bin/matlab

Enter the command  quit  to exit from the MATLAB environment.

To invoke MATLAB to execute the MATLAB program file file_name.m, enter:

/software/matlab/bin/matlab <file_name.m

The SAS System

is a comprehensive collection of data analysis and report generation products produced by SAS Institute Inc in Cary, NC.

SAS Version 9 is currently installed only on the VT ARC system Dante and has been installed in the directory   "/software/sasv9".

You can invoke the SAS processor to execute SAS program code in the file   "sas_file_name.sas"   by entering the following command:

/software/sasv9/sas  sas_file_name.sas

The results of running your program will be saved in the file   "sas_file_name.lst"; the sas output log and error diagnostics will be saved in the file:   "sas_file_name.log".

Gauss

provides tools for mathematical and statistical analysis.

To use Gauss with the Korn or BASH shells to run the program contained in the file "gauss_test.txt" in the current directory and save the results in the file "gauss_test.log", enter the following sequence of commands:

TGAUSSHOME='/software/gauss'
LD_LIBRARY_PATH='/software/gauss'
export TGAUSSHOME LD_LIBRARY_PATH
/software/gauss/tgauss  -b gauss_test.txt  >gauss_test.log

    /software/R-2.5.1/bin/R  --vanilla <test.r >test.out

Compilers

The Sun ONE Studio Fortran and C Compilers (Forte Compiler Collection 7, formerly known as Forte Developer 7) are now available on Dante:

To compile the Fortran program "test_prog.f" using the f95 compiler from this collection, enter:

/opt/SUNWspro/bin/f95  test_prog.f

To compile the C Language program "test_prog.c" using the cc compiler from this collection, enter:

/opt/SUNWspro/bin/cc  test_prog.c

Note:  If you prefer to use the GNU C compiler, use   "/opt/sfw/bin/gcc"  instead of  "/opt/SUNWspro/bin/cc"  above.

Subroutine Libraries

The following subroutine libraries are currently installed on the system:

IMSL

The IMSL Version 5.5 Mathematics and Statistics Subroutine Libraries are now available on Styx and Dante; IMSL provides a collection of subroutines for Mathematical and Statistical computations;   for details regarding use of the IMSL routines, see IMSL Online Documentation.

Since Styx has a larger number and faster processors, it is recommended that you use Styx when using the IMSL subroutine library on the VT ARC systems. If you wish to use Dante, substitute  "/software/imsl5.5"  for  "/apps/vni"  in the examples below:

Prior to using the IMSL subroutine libraries, you must define a series of environmental variables which are required by IMSL. If you are using the Bourne or Korn shell, use the following commands:

. /apps/vni/CTT6.0/ctt/bin/cttsetup.sh

If you are using the C Shell, use the following commands:

source /apps/vni/CTT6.0/ctt/bin/cttsetup.csh

Once you have defined the environmental variables as described above, you can then use the following command to compile the C program t_imsl.c:

/opt/SUNWspro/bin/cc  -o test_imsl  $CFLAGS  t_imsl.c  $LINK_CNL

Note: Any C language program that uses functions from the IMSL C/Math/Library must contain the include directive  "include <imsl.h>";  any C language program that uses functions from the IMSL C/Stat/Library must contain the include directive  "include <imsls.h>".

In order to use the IMSL Version 5 Fortran libraries in the SUN environment, you must use the Sun ONE Studio Fortran compiler. For example, you could use the following command to compile the Fortran program test_imsl.f:

/opt/SUNWspro/bin/f90 -o test_imsl $F90FLAGS test_imsl.f $LINK_F90
