AC account setup

You will be provided with your AC cluster username and password in class.  
Log in to ac.ncsa.uiuc.edu through an ssh program.  
The major details of system usage are included in /usr/local/share/ac.readme


To set up your CUDA sdk, copy 
/usr/local/cuda/cuda-sdk-linux-2.10.1215.2015-3233425.run 
to your local directory, change the permissions to allow execution, and run it.  
The install will prompt you for the installation location you prefer.  
Once extracted, cd into the sdk/common directory and run the commands
make
make dbg=1
This will build the release and debug version of the cutil libraries.  
The MPs will be tailored to be built within the CUDA SDK environment.  

Although the login node does contain CUDA cards to allow CUDA program 
execution, it is strongly recommended that you primarily use the queue 
submission script to use the entire cluster and prevent excessive load on the 
head node for CUDA jobs that may take longer than a few seconds.  
Information for how to use the qsub system in in the ac.readme file, 
but here are the basic details.  

qsub -I will let you log in to one of the AC cluster nodes directly and execute 
programs on it.  The walltime option is recommended for courtesy's sake.  Please 
do most of your development on the head node to not tie up cluster resources excessively.  

qsub with a script instead of -I will let you provide an executable script that will 
be run when the job reaches your intended node.  The stdout stream will be returned in a file.
