NAME
drmaa_run_job, drmaa_run_bulk_jobs, drmaa_get_next_job_id, drmaa_release_job_ids - Job submission

SYNOPSIS
#include "drmaa.h"

int drmaa_run_job(
    char *job_id,
    size_t job_id_len,
    drmaa_job_template_t *jt,
    char *error_diagnosis,
    size_t error_diag_len
);

int drmaa_run_bulk_jobs(
    drmaa_job_ids_t **jobids,
    drmaa_job_template_t *jt,
    int start,
    int end,
    int incr,
    char *error_diagnosis,
    size_t error_diag_len
);

int drmaa_get_next_job_id(
    drmaa_job_ids_t* values,
    char *value,
    int value_len
);

void drmaa_release_job_ids(
    drmaa_job_ids_t* values
);

DESCRIPTION
drmaa_run_job() submits an Grid Engine job with attributes defined in the DRMAA job template, jt. On success up to job_id_len bytes of the job identifier are returned into the buffer, job_id.

  drmaa_run_bulk_jobs()
The drmaa_run_bulk_jobs() submits a Grid Engine array job very much as if the option `-t start-end:incr' had been used along with the additional attributes defined in the DRMAA job template, jt. The same constraints regarding value ranges are also in effect for the parameters start, end, and incr as for -t. On success a DRMAA job id string vector containing job identifiers for each array job task is returned into jobids. The job identifiers in the job id string vector can be extracted using The caller is responsible for releasing the job id string vector returned into jobids using

  drmaa_get_next_job_id()
Each time drmaa_get_next_job_id() is called it returns into the buffer, value, up to value_len bytes of the next entry stored in the DRMAA job id string vector, values.

  drmaa_release_job_ids()
The drmaa_release_attr_job_id() function releases all resources associated with the DRMAA job id string vector, values. This operation has no effect on the actual Grid Engine array job tasks.

ENVIRONMENTAL VARIABLES

SGE_ROOT
    Specifies the location of the Grid Engine standard configuration files.

SGE_CELL
    If set, specifies the default Grid Engine cell to be used. To address a Grid Engine cell Grid Engine uses (in the order of precedence):

        The name of the cell specified in the environment variable SGE_CELL, if it is set.

        The name of the default cell, i.e. default.

SGE_DEBUG_LEVEL
    If set, specifies that debug information should be written to stderr. In addition the level of detail in which debug information is generated is defined.

SGE_QMASTER_PORT
    If set, specifies the tcp port on which is expected to listen for communication requests. Most installations will use a services map entry instead to define that port.

RETURN VALUES
Upon successful completion, drmaa_run_job(), drmaa_run_bulk_jobs(), and drmaa_get_next_job_id() return DRMAA_ERRNO_SUCCESS. Other values indicate an error. Up to error_diag_len characters of error related diagnosis information is then provided in the buffer error_diagnosis.

ERRORS
The drmaa_run_job(), drmaa_run_bulk_jobs(), and drmaa_get_next_job_id() will fail if:

  DRMAA_ERRNO_INTERNAL_ERROR
Unexpected or internal DRMAA error, like system call failure, etc.

  DRMAA_ERRNO_DRM_COMMUNICATION_FAILURE
Could not contact DRM system for this request.

  DRMAA_ERRNO_AUTH_FAILURE
The specified request is not processed successfully due to authorization failure.

  DRMAA_ERRNO_INVALID_ARGUMENT
The input value for an argument is invalid.

  DRMAA_ERRNO_NO_ACTIVE_SESSION
Failed because there is no active session.

  DRMAA_ERRNO_NO_MEMORY
Failed allocating memory.

The drmaa_run_job() and drmaa_run_bulk_jobs() functions will fail if:

  DRMAA_ERRNO_TRY_LATER
The DRM system indicated that it is too busy to accept the job. A retry may succeed, however.

  DRMAA_ERRNO_DENIED_BY_DRM
The DRM system rejected the job. The job will never be accepted due to DRM configuration or job template settings.

The drmaa_get_next_job_id() will fail if:

  DRMAA_ERRNO_INVALID_ATTRIBUTE_VALUE
When there are no more entries in the vector.
