NAME¶
slurm_init_job_desc_msg, slurm_init_update_step_msg, slurm_update_job,
slurm_update_step - Slurm job and step update functions
SYNTAX¶
#include <slurm/slurm.h>
void
slurm_init_job_desc_msg (
job_desc_msg_t *
job_desc_msg_ptr
);
void
slurm_init_update_step_msg (
step_update_request_msg_t *
step_msg
);
int
slurm_update_job (
job_desc_msg_t *
job_msg
);
int
slurm_update_step (
step_update_request_msg_t *
step_msg
);
ARGUMENTS¶
- job_msg
- Specifies the pointer to a job descriptor. See slurm.h for full details on
the data structure's contents.
- step_msg
- Specifies the pointer to a step descriptor. See slurm.h for full details
on the data structure's contents.
DESCRIPTION¶
slurm_init_job_desc_msg Initialize the contents of a job descriptor with
default values. Execute this function before issuing a request to submit or
modify a job.
slurm_init_update_step_msg Initialize the contents of a job step update
descriptor with default values. Execute this function before issuing a request
to modify a job step.
slurm_update_job Update a job with the changes made to the data structure
passed as an argument to the function.
slurm_update_step Update a job step with the changes made to the data
structure passed as an argument to the function.
RETURN VALUE¶
On success, zero is returned. On error, -1 is returned, and the Slurm error code
is set appropriately.
ERRORS¶
SLURM_PROTOCOL_VERSION_ERROR Protocol version has changed, re-link your
code.
ESLURM_ACCESS_DENIED The requesting user lacks authorization for the
requested action (e.g. trying to modify another user's job).
ESLURM_INVALID_JOB_ID Invalid job or step ID value.
ESLURM_INVALID_TIME_VALUE Invalid time value.
EXAMPLE¶
#include <stdio.h>
#include <slurm/slurm.h>
#include <slurm/slurm_errno.h>
int main (int argc, char *argv[])
{
job_desc_msg_t update_job_msg;
step_update_request_msg_t update_step_msg;
slurm_init_job_desc_msg( &update_job_msg );
update_job_msg.job_id = 1234;
update_job_msg time_limit = 200;
if (slurm_update_job (&update_job_msg)) {
slurm_perror ("slurm_update_job error");
exit (1);
}
slurm_init_update_step_msg( &update_step_msg );
update_step_msg.job_id = 1234;
update_step_msg.step_id = 2;
update_step_msg time_limit = 30;
if (slurm_update_step (&update_step_msg)) {
slurm_perror ("slurm_update_step error");
exit (1);
}
exit (0);
}
NOTE¶
These functions are included in the libslurm library, which must be linked to
your process for use (e.g. "cc -lslurm myprog.c").
