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.
