CIMS has two servers running that are are powering 4 AMD Fire GL V7800s that are allocated for OpenCL/AMD APP (Accelerated Parallel Processing) SDK usage.  Each system is connected to 2 GPUs.  These systems are capable of both single and double floating point precession calculations.

The hardware is available on opencl1.cims.nyu.edu and opencl2.cims.nyu.edu.  These machines are restricted to logins from within the Courant network, so if you are coming from outside of CIMS, you will have to first login to access.cims.nyu.edu, then use ssh to get to them.

Once logged in you can get setup running OpenCL/AMD APP code by following these instructions:

If using a bash/korn shell run:

export DISPLAY=:0

Else run:

setenv DISPLAY :0

Then test it out with:

mkdir amd-app-sdk
cd amd-app-sdk
cp -r /usr/local/pkg/amd-app-sdk/current/* ./
make
./bin/x86_64/clinfo
cd samples/opencl/bin/x86_64/
./HelloCL

See the AMD APP SDK doucmentation for  more information.

If you run into problems, please let us know as we'd like to try and get all the kinks worked out.
