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 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.

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.
