CUDAの使い方

GPUを使用するジョブのGrid Engineへの投入方法

GPUを使用するジョブを投入する場合、-l gpuオプションの他-l cuda=n(nは使用するGPU数を指定。上限は4)オプションを付与します。"-l cuda=n"オプションを付与しない場合、ジョブはgpu.qに投入されますが、GPUは使用できません。

例えば2つのGPUを使用する場合、以下のように指定します。

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

GPUはジョブから、cuda=nで指定した数だけ参照可能です。

[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
