SAS is a commercial integrated system for statistical analysis, data mining, and graphics as well as many enterprise oriented additional features. SAS cost and the breadth of SAS features means that both a significant monetary investment and a substantial time investment are required to master it. SAS 9.3 Documentation is vast. For research purposes the SAS 9.3 User's Guide is a thorough reference for the functions and procedures you may need to do the statistical analysis using SAS.

How To Run


SAS has a number of options:

Batch Submission

To do a batch submission of a SAS script use the -sysin command line option and write all of your SAS commands in a file. In this way you can submit jobs to the batch queue system to run your jobs on the cluster.

-work directory

SAS is a mature product with a long history behind it. In a modern high-performance environment it means that additional actions need to be taken to mitigate potential issues stemming from SASs focus on filesystem I/O instead of using memory.

Interactive Use

To connect to a test node, for example test01, where you can run the graphical interface to SAS use the following or a similar command on a linux or MacOS X system:

ssh USER@test01.ufhpc -o ForwardX11=yes -o ForwardX11Trusted=yes -o ProxyCommand='ssh USER@submit.hpc.ufl.edu exec nc test01 %p'

or add the following to your ~/.ssh/config file:

Host test01
   User USER
   KeepAlive yes
   ProxyCommand ssh USER@submit.hpc.ufl.edu exec nc test01 %p
   ForwardX11 yes
   ForwardX11Trusted yes

where USER is your username. After editing ~/.ssh/config you can just run the following command to connect:

ssh test01

Once connected run

module load sas
