  1. Introduction to IMSL and VNI Welcome to IT’s seminar on Visual Numerics Inc (VNI) package Sam Gordji, ccsam@olemiss.edu Weir 107

  2. List of Statistical Packages • SPSS • SAS • Mathematica • MathWorks (Matlab) • VNI (IMSL, PV-WAVE)

  3. General Information • SAS performs statistical analysis • SPSS performs statistical analysis and is similar to SAS • Mathematica’s main function is to perform mathematical operations including statistics • MathWorks is similar to Mathematica and is available on willow and sweetgum

  4. Statistical Package:SAS/PC (cont.) • 50 copies are available for faculty use • For each copy purchased, a faculty member can get a free copy (to be installed on a student PC) • The cost is $100 per copy per year • To obtain a copy of SAS please email • ccsam@olemiss.edu • assist@mcsr.olemiss.edu

  5. List of Statistical Packages Mathematica • Mathematica (free copy for faculty, staff, and students). To obtain a copy of Mathematica please visit: http://www.mcsr.olemiss.edu/appssubpage.php?pagename=mathematica.inc

  6. List of Statistical Packages Matlab • Matlab (available on willow and sweetgum) • VNI is the parent company of JMSL, IMSL, PV-WAVE etc.

  7. List of VNI Packages IMSL • IMSL for Fortran is a comprehensive package containing Math, stat., and special functions • IMSL for C++ is a comprehensive package containing Math, stat., and special functions • IMSL is available only on sweetgum • IMSL is a set of subroutines called by a Fortran, c or a Java program

  8. General Information • Email contact • Email your questions to assist@mcsr.olemiss.edu • To download this and other materials visit: http://www.mcsr.olemiss.edu/educationsubpage.php?pagename=sepcamp08.inc • Please fill out the performance report and leave your email address so we may contact you for follow up questions

  9. General Information • This seminar covers IMSL and Fortran • We’ll look at a few short IMSL examples

  10. General Information • IT staff will assist users to access these packages. We also assist users to find the proper procedure to analyze their data. If you need assistance please send an email to Sam Gordji at ccsam@olemiss.edu, assist@mcsr.olemiss.edu , or mathadm@olemiss.edu

  11. Accessing Fortran on willow and on sweetgum • Willow and sweetgum are Unix server housed in the data center building • Willow’s operating system is Sun Solaris (Solaris 10) • Willow and sweetgum are the primarily used by researchers that have large number crunching programs • Limited knowledge of Unix system is needed to run Fortran and IMSL

  12. Fortran on willow may be accessed from the network. Steps to access willow from a Windows PC: Request a willow account from the IT Helpdesk. Download/Install SSH Secure Shell Client from http://www.mcsr.olemiss.edu/appssubpage.php?pagename=ssh2.inc Click “Secure Shell Client” Accessing Fortran on Willow

  13. Accessing Fortran on Willow (Cont.) Click “Quick Connect”

  14. Accessing Fortran on Willow (Cont.) • For this workshop, everyone can login as student • Fill in “Host Name” and “User Name” as above • Click “Connect”

  15. A Few Useful Unix Commands • cat --- for displaying a file • cd --- change directory • cd 1--- to move to sub-directory 1 & so on • cp --- for copying files • ls --- see what files you have • pwd --- find out what directory you are in • rm --- remove a file • pico --- a Unix editor • sas --- to activate and run SAS programs • To attend a Unix seminar, please contact assist@mcsr.olemiss.edu

  16. Running Fortran on Willow and sweetgum • Willow is ready to execute Fortran jobs • cd to the numbered directory assigned to you, e.g. cd 5 • pwd to print working directory • ls to list files in working directory • To view a program, enter: cat file-name.f • To launch a SAS program, enter: f77 file-name.f

  17. Accessing Fortran on Willow • To run a Fortran job on willow or sweetgum enter: F77 my.f, where “my.f” is the name of your Fortran program To obtain an account for willow contact Helpdesk at: 915-5222

  18. Topics of the Day • Creating a simple Fortran Program • Running a few Fortran Program with and without IMSL (nonlin.f,eign.f, test.f, newton.f) • Looking at some aspects of Fortran & IMSL • Download Fortran programs form sweetgum: /usr/local/apple/examples

  19. Running Fortran on sweetgum • To create executable on sweetgum enter: • f90 $F90FLAGS -o nonlin nonlin.f $LINK_F90 • To run an script called "nonlin", simply enter: • nonlin • Please note that the executable in this case is called "nonlin"

  20. JMSL • JMSL Numerical Library is the collections of Mathematical, statistical and financial routines • Combines the power of IMSL and uses Java • Link below explains IMSL Libraries ( Math, Stat. and Special Functions) http://www.vni.com/products/imsl/jmsl/jmsl.php
