SAS, the statistical software, and much more, frequently used in the social sciences, is available on the High Performance Academic Computing Cluster. It is not a parallel version of SAS, but we do offer an unlimited campus wide license for Teaching and Research.

SAS is typically invoked in batch mode by submitting a script (*.sas text file). SAS will generate a log file (*.log) and a listing file (*.lst). The former shows you what is going on, the latter contains the output of invoked procedures.

SAS can be invoked in interactive mode on the head node for debugging and code development if needed. However, this is not supported on compute nodes. Hence if you need to generate graphical output you will have to use SAS/Graphics or the Output Delivery System (SAS/ODS). Examples of code can be found at a variety of locations:

• at sas.com http://support.sas.com/kb/?ct=51000&col=suppprd
• SAS/ODS examples http://sas.wesleyan.edu/statgraphs/
• SAS/Graphics examples Data Driven Images, Code

• A tutor is available at http://sas.wesleyan.edu/SASOnlineTutor/sot91/index.htm

So lets generate a little SAS program using a Unix editor like vi/vim, emacs or pico.

• First we generate the input data file test.dat

1234567890
0987654321
2468097531

• Next a simple SAS file test.sas which does the obvious

options nocenter;
filename test './test.dat';

data one;
  infile test;
  input @2 x 3.1 @6 y 3.1;
  total = x * y;
run;

proc print; run;

• Lets test it by submitting on head node

[root@greentail sas]# ll
total 8
-rw-r--r-- 1 root root  33 Dec 21 10:16 test.dat
-rw-r--r-- 1 root root 140 Dec 21 10:22 test.sas
[root@greentail sas]# sas test
[root@greentail sas]# cat test.lst
