[slurm-users] gres definitions

Hi, I have gres defined in my partition name. If I assign some bogus gres to a node, the partition stops working. Somehow Slurm and the OS agree on the gres installed. How do I find out all the named gres in my system, e.g. specific cpu types, not just "cpu". Thanks, John

[slurm-users] slurmctld daemon error

Re: [slurm-users] slurmctld daemon error

What does your ‘slurmctld.service’ look like? You might want to add something to the ‘After=’ section if your service is starting too quickly. e.g. we use ‘After=network.target munge.service’ (see here

[slurm-users] Scripts run slower in slurm?

Hi, I made a short script in python to test if slurm was correctly limiting the number of CPUs available to each partition. The script is as follows: import multiprocessing as mp import time as t def fibonacci(n): n = int(n) def fibon(a,b,n,result): c = a+b result.append(c
