Intel Xeon Phi Jobs¶
RCC’s Midway1 compute cluster contains two nodes with Intel Phi co-processor (also known as Xeon Phi Knights Corner) cards. Each Phi compute node contains dual 8-core intel Sandy Bridge processors, and two Intel Phi devices.
The Phi nodes are contained in the mic
partition. To compile software that interacts
with the Phi cards, you must use the Intel compilers available through these software
modules on Midway1:
intelmpi/5.0+intel-15.0
Here is a basic quickstart using interactive mode that will execute the samples provided with the intel compiler suite:
sinteractive -p mic --exclusive
module load intelmpi/5.0+intel-15.0
cp -r /software/intel/composer_xe_2015/Samples/en_US/C++/mic_samples/intro_sampleC ~/mictest
cd ~/mictest
make mic
./intro_sampleC.out
It is also possible to submit jobs via sbatch to the mic
partition. To do so,
the --partition=mic
option must be included in your submission script.
It should also be possible to compile and run OpenCL on the Phi cards without any additional configuration. Use this sample zip from Intel to verify that OpenCL is working
The Phi cards also mount the filesystem locally via NFS and it is possible to create an SSH connection into the cards from an interactive session on the node.
