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.  Note the effect of
       the SGE_DRMAA_ALLOW_JOB_ERROR_STATE environment variable, as below.

   drmaa_run_bulk_jobs()
       The drmaa_run_bulk_jobs() submits a Grid Engine array job very much as
       if the qsub(1) 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 qsub(5) -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 drmaa_get_next_job_id(3).  The number of
       identifiers in the job id string vector can be determined using
       drmaa_get_num_job_ids(3).  Note that this function is only available in
       the 1.0 implementation.  The caller is responsible for releasing the
       job id string vector returned into jobids using
       drmaa_release_job_ids(3).

   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.  Once the job ids list has been exhausted,
       DRMAA_ERRNO_NO_MORE_ELEMENTS is returned.

   drmaa_get_num_job_ids()
       The drmaa_get_num_job_ids() returns into size the number of entries in
       the DRMAA job ids string vector.  This function is only available in
       the 1.0 implementation.

   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 sge_qmaster(8)
                      is expected to listen for communication requests.  Most
                      installations will use a services map entry instead to
                      define that port.

       SGE_DRMAA_ALLOW_JOB_ERROR_STATE
                      If set, in case of job errors the job will enter the
                      error state.  By default DRMAA jobs are not allowed to
                      enter the job error state since an error state does not
                      exist in DRMAA, so jobs with, say, a wrong input path
                      specification, must fail when doing drmaa_wait().


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()
       functions can fail with:

       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 can fail with:

       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() function can fail with:

       DRMAA_ERRNO_INVALID_ATTRIBUTE_VALUE
              When there are no more entries in the vector.
