I think this may be more on how you are calling mpirun and the mapping of processes. With the "--exclusive" option, the processes are given access to all the cores on each box, so mpirun has a choice. IIRC, the default is to pack them by slot, so fill one node, then move to the next. Whereas y

Hi, Thanks, so I have to install and enable the client part of slurm (slurmd) on the manager host along side with slurmctld. Regards. Le mar. 30 juil. 2019 à 14:23, Daniel Letai a écrit : > Yes, just add it to the Nodes= list of the partition. > > You will have to install slurm-slurmd on it as

Yes, just add it to the Nodes= list of the partition. You will have to install slurm-slurmd on it as well, and enable and start as on any compute node, or it will be DOWN. HTH, --Dani_L. On 7/30/19 3:45 PM, wodel youchi wrote:

Hi, I am newbie in Slurm, All examples I saw when they declare the Partition, only compute nodes are used. My question is : can I use the manager or the slurmctldhost (the master host) as a compute node in and extended partition for example? if yes how? Regards.

[slurm-users] Unexpected MPI process distribution with the --exclusive flag

2019-07-30 Thread CB
Hi Everyone, I've recently discovered that when an MPI job is submitted with the --exclusive flag, Slurm fills up each node even if the --ntasks-per-node flag is used to set how many MPI processes is scheduled on each node. Without the --exclusive flag, Slurm works fine as expected. Our system i
