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.
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
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.
