OpenCL now Available on Dirac GPU Cluster

As requested by many Dirac users, NERSC is migrating Dirac to a newer Linux version to enable capabilities such as OpenCL. We aim to convert the whole Dirac system to Scientific Linux 6.3 by Mid-November. 
 
We have migrated the beta nodes to Scientific Linux 6.3. Please run some test jobs to make sure your code will work in the new system. In particular, please test your MPI+Cuda codes in a multi-node environment. 
 
You can get to one of these nodes with:
qsub -I -V -q dirac_int -l nodes=1:ppn=8:beta

Or to get 2 nodes:
qsub -I -V -q dirac_reg -l nodes=2:ppn=8:beta

Inside the job you need to load the latest cuda and SL6 flavor of gcc:
module unload cuda
module load cuda/5.5
module unload pgi
module load gcc-sl6

If you dont have access to Dirac you may request access:
