DESCRIPTION
The drmaa_strerror() function returns a message text associated with the DRMAA error number, drmaa_errno. For invalid DRMAA error codes ’NULL’ is returned.
drmaa_get_contact()
The drmaa_get_contact() returns an opaque string containing
contact information related to the current DRMAA session to
be used with the drmaa_init(3) function. The opaque
string contains the information required by drmaa_init() to
reconnect to the current session instead of creating a new
session. drmaa_init(3) function.
The drmaa_get_contact() function returns the same value before and after drmaa_init(3) is called.
drmaa_version()
The drmaa_version() function returns into the integers
pointed to by major and minor, the major and
minor version numbers of the DRMAA library. For a DRMAA 1.0
compliant implementation ’1’ and ’0’
will be returned in major and minor,
respectively.
drmaa_get_DRM_system()
The drmaa_get_DRM_system() function returns into
drm_system up to drm_system_len characters of
a string containing Grid Engine product and version
information.
The drmaa_get_DRM_system() function returns the same value before and after drmaa_init(3) is called.
drmaa_get_DRMAA_implementation()
The drmaa_get_DRMAA_implementation() function returns into
drm_system up to drm_system_len characters of
a string containing the Grid Engine DRMAA implementation
version information. In the current implementation, the
drmaa_get_DRMAA_implementation() function returns the same
result as the drmaa_get_DRM_system() function.
The drmaa_get_DRMAA_implementation() function returns the same value before and after drmaa_init(3) is called.
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_get_contact(), drmaa_version(), and drmaa_get_DRM_system() 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_get_contact(), drmaa_version(),
drmaa_get_DRM_system(), and drmaa_get_DRMAA_implementation()
can fail with:
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_MEMORY
Failed allocating memory.
The
drmaa_get_contact() and drmaa_get_DRM_system() can fail
with:
DRMAA_ERRNO_NO_ACTIVE_SESSION
Failed because there is no active session.
