CUDA

How to submit jobs that uses GPU to Grid Engine​

When submitting jobs that uses GPU, use the -l cuda=n (n specifies the number of GPUs to use. The upper limit is 4.) option in addition to the -l gpu option. If the "-l cuda=n" option is not used, the job will be submitted to gpu.q, but no GPUs can be used.

For example, when you use two GPUs, specify as follows.

[username@at027 ~]$ qsub -l gpu -l cuda=2 gputest.sh
Your job 10000 ("gputest.sh") has been submitted

The GPU can be referenced from the job by the number specified by cuda = n.

[username@at027 ~]$ cat gputest.sh
#!/bin/bash
#$ -S /bin/bash

nvidia-smi
[username@at027 ~]$ qsub -l gpu -l cuda=1 gputest.sh 
Your job 10001 ("gputest.sh") has been submitted
[username@at027 ~]$ qsub -l gpu -l cuda=2 gputest.sh 
Your job 10002 ("gputest.sh") has been submitted
[username@at027 ~]$ qsub -l gpu -l cuda=4 gputest.sh 
Your job 10003 ("gputest.sh") has been submitted
[username@at027 ~]$ cat gputesh.sh.o10001
