Thanks for the quick answer! That's my problem. I will try to re-explain :
I have to initialize these variables (SLURM_JOB_ID, SLURM_NNODES, SLURM_NODEID
& SLURM_LOCALID) but without using srun command. My client still wants to use
his API to execute mulithreaded jobs on cluster environments. He just wants to
replace some of his functionnalities with SLURM ones.
For example, to get the job id :
void get_job_id(int * job_id) {
sprintf(getenv("SLURM_JOBID"), "%d", *job_id);
}
To do that, I need to initialize all the environment variables, but without
using srun. I think I have to use the initialize_and_process_args function, but
it is not in SLURM's includes (/usr/local/slurm-2.2.4/include).
More clear?
Best regards

I am not certain that I understand your question, but there are SLURM
environment variables set with the information that you describe. See the
section "OUTPUT ENVIRONMENT VARIABLES" in the srun man page.

Subject: [slurm-dev] Link SLURM with an other API
Hi all,
I am new to SLURM, and I hope my question is not stupid.
My client had developed his own API to manage processes and resources in a
multithreading context on clusters environment. Now he wants to replace some
modules by opensource ones as SLURM.
More precisely, he wants to use some SLURM functionnalities : query job id,
rank node, etc. To do that, I need to init correctly all my structures, but
functions I need are not in SLURM includes (slurm.h & cie). I precise the API
must be linked with SLURM, and must not use SLURM sources.
So, how can I initialize job id, nodes & processes ranks, nodes & processes
number, … ?
Thanks for your help.
