[OMPI users] Errors when compiled with Cygwin MinGW gcc

Re: [OMPI users] Slot count parameter in hostfile ignored

My best guess is that SLURM has only allocated 2 slots, and we respect the RM regardless of what you say in the hostfile. You can check this by adding --display-allocation to your cmd line. You probably need to tell slurm to allocate more cpus/node. > On Sep 7, 2017, at 3:33 AM, Maksym

[OMPI users] Slot count parameter in hostfile ignored

Hello, I'm trying to tell OpenMPI how many processes per node I want to use, but mpirun seems to ignore the configuration I provide. I create following hostfile: $ cat hostfile.16 taurusi6344 slots=16 taurusi6348 slots=16 And then start the app as follows: $ mpirun --display-map
