#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 ); int drmaa_get_num_job_ids( drmaa_job_ids_t* values, int *size ); void drmaa_release_job_ids( drmaa_job_ids_t* values );
drmaa_run_job() submits an Sun 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 Sun 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 Sun Grid Engine array job tasks.
SGE_ROOT Specifies the location of the Sun Grid Engine standard configuration files. SGE_CELL If set, specifies the default Sun Grid Engine cell to be used. To address a Sun Grid Engine cell Sun 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.
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.
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.
