DESCRIPTION
The drmaa_job_ps() function returns the status of the Grid Engine job job_id into the integer pointed to by remote_ps. Possible return values are listed below. See for the correspondence between them and the Grid Engine status.
-
DRMAA_PS_UNDETERMINED job status cannot be determined DRMAA_PS_QUEUED_ACTIVE job is queued and active DRMAA_PS_SYSTEM_ON_HOLD job is queued and in system hold DRMAA_PS_USER_ON_HOLD job is queued and in user hold DRMAA_PS_USER_SYSTEM_ON_HOLD job is queued and in user and system hold DRMAA_PS_RUNNING job is running DRMAA_PS_SYSTEM_SUSPENDED job is system suspended DRMAA_PS_USER_SUSPENDED job is user suspended DRMAA_PS_DONE job finished normally DRMAA_PS_FAILED job finished, but failed
Jobs' user hold and user suspend states can be controlled via For affecting system hold and system suspend states the appropriate Grid Engine interfaces must be used.
drmaa_control()
The drmaa_control() function applies control operations on Grid Engine jobs. jobid may contain either an Grid Engine jobid or `DRMAA_JOB_IDS_SESSION_ALL' to refer to all jobs submitted during the DRMAA session opened using Legal values for action and their meanings are:
-
DRMAA_CONTROL_SUSPEND suspend the job DRMAA_CONTROL_RESUME resume the job DRMAA_CONTROL_HOLD put the job on-hold DRMAA_CONTROL_RELEASE release the hold on the job DRMAA_CONTROL_TERMINATE kill the job
The DRMAA suspend/resume operations are equivalent to the use of -sj jobid and -usj jobid options with Grid Engine The DRMAA hold/release operations are equivalent to the use of Grid Engine and The DRMAA terminate operation is equivalent to the use of Grid Engine Only user hold and user suspend can be controlled via For affecting system hold and system suspend states the appropriate Grid Engine interfaces must be used.
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.
-
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_job_ps(), and drmaa_control() 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_job_ps() and drmaa_control() functions may 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 was 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.
- DRMAA_ERRNO_INVALID_JOB
- The specified job does not exist.
The drmaa_control() function may fail with:
- DRMAA_ERRNO_RESUME_INCONSISTENT_STATE
- The job is not suspended. The resume request will not be processed.
- DRMAA_ERRNO_SUSPEND_INCONSISTENT_STATE
- The job is not running and thus cannot be suspended.
- DRMAA_ERRNO_HOLD_INCONSISTENT_STATE
- The job cannot be moved to a hold state.
- DRMAA_ERRNO_RELEASE_INCONSISTENT_STATE
- The job is not in a hold state.
