Introduction to Fortran Welcome to IT’s seminar on Fortran Sam Gordji, Weir 107

List of Statistical Packages  SPSS  SAS  Mathematica  MathWorks (Matlab)

General Information  SAS performs statistical analysis  SPSS also 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

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 $200 per copy per year (starting Aug. 09)  To obtain a copy of SAS please 

List of Statistical Packages Mathematica  A free copy is available for faculty, staff, and students. To obtain a copy of Mathematica please visit: php?pagename=mathematica.inc

List of Statistical Packages  Matlab is available on willow and sweetgum  Fortran is available on willow, mimosa, redwood and sweetgum  Fortran is the oldest program that solves engineering problems

General Information  contact – your questions to  To download this and other materials visit: pagename=marcamp09.inc pagename=marcamp09.inc  Please fill out the performance report and leave your address so we may contact you for follow up questions

General Information  This seminar covers Fortran on willow, redwood and sweetgum  We’ll take a look at a few short examples of Fortran  MCSR has several examples of Fortran

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 to Sam Gordji at or

Accessing Fortran on Willow, sweetgum or redwood  To run a Fortran job on willow, redwood 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:

Accessing Fortran on Willow 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 –Click “Secure Shell Client”

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

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

Accessing Fortran on Willow (Cont.)  Enter your password  Click “OK”

Running Fortran on Willow  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 Fortran program, enter: f77 file-name.f

Running Fortran on Willow  Creating or downloading a simple Fortran Program  Running a few Fortran Programs on willow (test.f,chen99.f, newton.f)  Looking at some aspects of Fortran  Running Fortran programs from sweetgum  Running fortran example “rawls.f” from path: fortnon

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  F to compile a Fortran programs  To attend a Unix seminar, please contact

Example of test.f  c to run this program on willow enter: f77 test.f, which is the name of this program. BLUE LINES ARE COMMENTS  x=1.0  w=4.*x  y=2.0  z=x+y  c open statement below creates an output file called 'output'.  open(6,file='output')  write(6,100)x,y,z,w  c write statement writes the values of x,w,y, and z.  100 format(2x,4f10.2)  stop  end
