Slurm API(3) Slurm job step initiation functions Slurm API(3)
NAME
slurm_free_job_step_create_response_msg, slurm_job_step_create - Slurm job step initiation functions
SYNTAX
#include <slurm/slurm.h>
void slurm_free_job_step_create_response_msg (
job_step_create_response_msg_t *slurm_step_alloc_resp_msg_ptr
);
int slurm_job_step_create (
job_step_create_request_msg_t *slurm_step_alloc_req_msg_ptr,
job_step_create_response_msg_t **slurm_step_alloc_resp_msg_pptr
);
ARGUMENTS
slurm_step_alloc_req_msg_ptr
Specifies the pointer to the structure with job step request specification. See slurm.h for full details on the data structure's
contents.
slurm_step_alloc_resp_msg_pptr
Specifies the double pointer to the structure to be created and filled with a description of the created job step: node allocation,
credentials, etc. See slurm.h for full details on the data structure's contents.
DESCRIPTION
slurm_free_job_step_create_response_msg Release the storage generated in response to a call of the function slurm_job_step_create.
slurm_job_step_create Initialize a job step including the allocation of nodes to it from those already allocate to that job. Always release
the response message when no longer required using the function slurm_free_job_step_create_response_msg. The list of host names returned
may be matched to their data in the proper order by using the functions hostlist_create, hostlist_shift, and hostlist_destroy.
RETURN VALUE
On success, zero is returned. On error, -1 is returned, and Slurm error code is set appropriately.
ERRORS
SLURM_PROTOCOL_VERSION_ERROR Protocol version has changed, re-link your code.
ESLURM_INVALID_JOB_ID the requested job id does not exist.
ESLURM_ALREADY_DONE the specified job has already completed and can not be modified.
ESLURM_ACCESS_DENIED the requesting user lacks authorization for the requested action (e.g. trying to delete or modify another user's job).
ESLURM_DISABLED the ability to create a job step is currently disabled. This is indicative of the job being suspended. Retry the call as
desired.
ESLURM_INTERCONNECT_FAILURE failed to configure the node interconnect.
ESLURM_BAD_DIST task distribution specification is invalid.
SLURM_PROTOCOL_SOCKET_IMPL_TIMEOUT Timeout in communicating with SLURM controller.
NOTE
These functions are included in the libslurm library, which must be linked to your process for use (e.g. "cc -lslurm myprog.c").
