There's the handy "nproc" command which will tell you how many cores you can actually use - it's cgroups aware so it won't just blindly report all the cores in the host. It's also part of coreutils so you should be able to rely on it being there. > Resubmitted the request asking for all CPU's and the job ran in the expected > amount of time. Great news!
