I've been wracking my brain, but for the life of me can't recall the exact program name, but back when I managed a HPCC, there was a tool that would let you restrict a running process to X number of CPUs/Cores natively. I keep thinking it was MPC, but nothing googles on that. Regardless, that might be a better way of running Sybase, as a container may not be beefy enough to handle the load Sybase is likely to generate.
Yeah, mpich, I think - one of my users uses that; on our other clusters, we've been using torque, though we're slowly moving to slurm.
I agree with you though, I don't know that doing it that way will work - I think Sybase *looks* at the number of cores it can see, probably some of the license info it uses.

Hi, folks,
We would like to run a container on a server, the reason being the COST of a Sybase license (it's by core), and what we can afford is a 4-core license. Now, the server's a nice Dell w/ 32 cores, so, ideally, what we want to do is set up containers, then, in one container, *only* have it see 4 cores, while the rest of the server, including (possibly) other containers, can see the other 28. The first try seems to have disabled *all* the cores other than those four.
Is it possible to do what we want, and if so, some pointers would be most appreciated.
