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 and

  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 The caller is responsible for releasing the DRMAA values string vector returned into values using

  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. With the DRMAA 1.0 library, once the values list has been exhausted, DRMAA_ERRNO_NO_MORE_ELEMENTS is returned. With the DRMAA 0.95 library, once the values list has been exhausted, DRMAA_ERRNO_INVALID_ATTRIBUTE_VALUE is returned. In order to use the DRMAA 0.95 library, you must define the DRMAA_95 macro, either in your application directly or through a compiler flag, such as -DDRMAA_95.

  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 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_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.
