Hello,
With Slurm, you can use "salloc --gpus=12" to allocate 12 GPUs, and Slurm will automatically allocate the number of nodes needed to satisfy the 12 GPU requirement. For example, if each GPU node has 4 GPUS, then "salloc --gpus=12" will automatically allocate 3 nodes, since (3 nodes x 4 GPUs each) = 12 GPUs total.
It this possible with PBS? I tried "qsub -l ngpus=12 ...", but "qstat" reports:
Can Never Run: Insufficient amount of resource: sales_op (none != )
I don't want to have to specify "-l nodes=" or "-l select=", since I would solely like the number of nodes that PBS allocates to be based on the number of GPUs requested.
Any suggestions on how to do this with PBS would be greatly appreciated.
Thank you.
