chsh on Forge with no passwords?

2011-10-17T20:35:26Z

Hi, I seem to be spamming the forum with questions today.

I would really like to change my login shell on Forge to /bin/bash rather than the default /bin/tcsh. However, Forge seems to allow only password-less login, so I can't figure out how to use chsh since it asks for a password. Is there some trick to do this?

Is an entire node on Forge the minimum allocation?

Hi, after looking through the Forge users guide, I had one question:
When submitting a job, is the minimum resource allocation always an entire node (16 CPU cores + 6 CUDA devices)? (I see that the charging formula is in units of nodes, not CUDA devices.)

We typically run our software locally in a mode where a job only uses 4 CPU cores and 1 CUDA device, but if the Forge scheduler is reserving an entire node for a job, our code will tremendously underutilize the hardware. We could adjust things to use multiple CUDA devices per job without too much trouble, however. Should we go that direction?

Hi, I recently received an allocation on the new Forge GPU cluster. I can't seem to find a user's guide for that cluster, however.

I'm looking for information on how the batch queue system works, what filesystems I should use for programs vs. data, and how the CUDA device allocation works for batch jobs.

Any pointers?
