Smilei on Polaris (ALCF)

[MartaGalbi]

Hi,

to compile and run Smilei on Polaris, a machine with PBS scheduler, I need to modify Smilei.cpp in this way:

//local_rank_env = getenv("SLURM_LOCALID");

local_rank_env = getenv("PMI_LOCAL_RANK");

Can this be included in the code?

I provide below the scripts needed to compile and run the code.
I compiled the code on computing nodes using the script smilei.profile placed in $HOME to setup properly the environment. To run I need the script set_affinity_gpu_polaris.sh (placed in my $HOME) and I use the job script job.pbs.

smilei.profile
set_affinity_gpu_polaris.sh
job.pbs

Hi, thank you for this contribution.

We might include a test in Smilei.cpp, something akin to: if SLURM_LOCALID is not defined we could try with PMI_LOCAL_RANK perhaps. Some testing will be required.

We might also add a machine file Polaris_pbs that includes the environnement and keeps a trace of the way the affinity was set.
