DESCRIPTION

The drmaa_allocate_job_template() function allocates a new DRMAA job template into jt. DRMAA job templates describe specifics of jobs that are submitted using drmaa_run_job(3) and drmaa_run_bulk_jobs(3).
drmaa_delete_job_template(): The drmaa_delete_job_template() function releases all resources associated with the DRMAA job template jt. Jobs that were submitted using the job template are not affected.
drmaa_set_attribute(): The drmaa_set_attribute() function stores the value under name for the given DRMAA job template, jt . Only non-vector attributes may be passed.
drmaa_get_attribute(): The drmaa_get_attribute() function returns into value up to value_len bytes from the string stored for the non-vector attribute, name, in the DRMAA job template, jt.
drmaa_set_vector_attribute(): The drmaa_set_vector_attribute() function stores the strings in value under name in the list of vector attributes for the given DRMAA job template, jt . Only vector attributes may be passed. The value pointer array must be NULL terminated.
drmaa_get_vector_attribute(): The drmaa_get_vector_attribute() function returns into values a DRMAA attribute string vector containing all string values stored in the vector attribute, name. The values in the DRMAA values string vector can be extracted using drmaa_get_next_attr_value(3). The caller is responsible for releasing the DRMAA values string vector returned into values using drmaa_release_attr_values(3).
drmaa_get_next_attr_value(): Each time drmaa_get_next_attr_value() is called it returns into value up to value_len bytes of the next entry stored in the DRMAA values string vector, values. Once the values list has been exhausted, DRMAA_ERRNO_NO_MORE_ELEMENTS is returned.
drmaa_get_num_attr_values(): The drmaa_get_num_attr_values() returns into size the number of entries in the DRMAA values string vector. This function is only available in the 1.0 implementation.
drmaa_release_attr_values(): The drmaa_release_attr_values() function releases all resources associated with the DRMAA values string vector, values.

ENVIRONMENTAL VARIABLES

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.

RETURN VALUES

Upon successful completion, drmaa_allocate_job_template(), drmaa_delete_job_template(), drmaa_set_attribute(), drmaa_get_attribute(), drmaa_set_vector_attribute(), drmaa_get_vector_attribute(), and drmaa_get_next_attr_value() 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_allocate_job_template(), drmaa_delete_job_template(), drmaa_set_attribute(), drmaa_get_attribute(), drmaa_set_vector_attribute(), drmaa_get_vector_attribute(), and drmaa_get_next_attr_value() functions 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_set_attribute() and drmaa_set_vector_attribute() will fail if:
DRMAA_ERRNO_INVALID_ATTRIBUTE_FORMAT: The format for the attribute value is invalid.
DRMAA_ERRNO_INVALID_ATTRIBUTE_VALUE: The value for the attribute is invalid.
DRMAA_ERRNO_CONFLICTING_ATTRIBUTE_VALUES: The value of this attribute is conflicting with a previously set attributes.; The drmaa_get_attribute() and drmaa_get_vector_attribute() will fail if:
DRMAA_ERRNO_INVALID_ATTRIBUTE_VALUE: The specified attribute is not set in the DRMAA job template.; The drmaa_get_next_attr_value() will fail if:
DRMAA_ERRNO_INVALID_ATTRIBUTE_VALUE: When there are no more entries in the vector.
