Re: [slurm-users] [External] Proposal for new TRES - "Processor Performance Units"....

Another option might be to estimate lifetime cost (purchasing price + average power consumption + maintenance) of each type of node and then base multipliers on that. Not all workloads correlate well with linpack. Many teaching institutions also give students some amount of core hours per month

Hi, Many MPI implementations will have some sort of core binding allocation policy - which may impact such node sharing. Would these only be limited to single CPU jobs? Can users request a particular core, for example for a GPU based job some cores will have better memory transfer rates to the

May be some aspects outside of slurms control that are tied to the machine you are using which require a specific way of handling environment variables. You might try the following: #!/bin/bash #SBATCH --job-name=my_job #SBATCH —time=01:00:00 for A in 1 2 do time ./my_code.o -a ${A} done On
