Hi,
I've been playing with allocating GPUs using gridengine and am wondering
if I'm trying to make it too complicated.
We have some 24 core, 128G RAM machines, each with two K80 GPU cards in
them. I have a little client/server program that allocates named cards to
jobs (via a starter method and the handy job gid).
What's left is the most important question: how do users request these
resources?
I'm worried that, if I ask them to specify all the job's resources, a
mouthful like "-pe smp 12 -l h_rt=1:0:0,h_vmem=64G,k80=1", just to get one
card, could all too easily result in a K80 sitting idle if the numbers are
tweaked a little.
Instead, I'm wondering if I should encourage users to request a number of
cards and then we allocate a proportion of cpu and memory based on that
(via per-slot complex, JSV and starter method).
Is that too simplistic, or would it be a welcome relief? What does the
qsub command line look like at other sites for requesting GPUs?
Mark
