drmaa_job_ps, drmaa_control, - Monitor and control jobs
const char *job_id,
const char *jobid,
The drmaa_job_ps() function returns the status of the Sun Grid Engine
job job_id into the integer pointed to by remote_ps. Possible return
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 Sun Grid Engine interfaces must be used.
The drmaa_control() function applies control operations on Sun Grid
Engine jobs. jobid may contain either an Sun 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 Sun Grid Engine qmod(1). The
DRMAA hold/release operations are equivalent to the use of Sun Grid
Engine qhold(1) and qrls(1). The DRMAA terminate operation is
equivalent to the use of Sun 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 Sun Grid Engine
interfaces must be used.
SGE_ROOT Specifies the location of the Sun Grid Engine standard
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.
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.
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() will fail if:
Unexpected or internal DRMAA error, like system call failure, etc.
Could not contact DRM system for this request.
The specified request was not processed successfully due to
The input value for an argument is invalid.
Failed because there is no active session.
Failed allocating memory.
The specified job does not exist.
The drmaa_control() will fail if:
The job is not suspended. The resume request will not be processed.
The job is not running and thus cannot be suspended.
The job cannot be moved to a hold state.
The job is not in a hold state.
