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 function. The opaque string contains the information required by drmaa_init() to reconnect to the current session instead of creating a new session. function.The drmaa_get_contact() function returns the same value before and after 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 Sun Grid Engine product and version information.The drmaa_get_DRM_system() function returns the same value before and after 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 Sun 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 is called.
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.
- The name of the cell specified in the environment variable SGE_CELL, if it is set.
-
- 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_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() 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_MEMORY
Failed allocating memory.The drmaa_get_contact() and drmaa_get_DRM_system() will fail if:
DRMAA_ERRNO_NO_ACTIVE_SESSION
Failed because there is no active session.SEE ALSO
