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.
