#include "drmaa.h" int drmaa_job_ps( const char *job_id, int *remote_ps, char *error_diagnosis, size_t error_diag_len ); int drmaa_control( const char *jobid, int action, char *error_diagnosis, size_t error_diag_len );
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 sge_status(5) 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 drmaa_control(3). 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 drmaa_init(3). 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 qmod(1). The DRMAA hold/release operations are equivalent to the use of Grid Engine qhold(1) and qrls(1). The DRMAA terminate operation is equivalent to the use of Grid Engine qdel(1). Only user hold and user suspend can be controlled via drmaa_control(3). For affecting system hold and system suspend states the appropriate Grid Engine interfaces must be used.
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.
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.
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.
