DESCRIPTION

26       The  drmaa_job_ps()  function returns the status of the Grid Engine job
27       job_id into the integer pointed to by remote_ps. Possible return values
28       are
29
30              DRMAA_PS_UNDETERMINED        job status cannot be determined
31              DRMAA_PS_QUEUED_ACTIVE       job is queued and active
32              DRMAA_PS_SYSTEM_ON_HOLD      job is queued and in system hold
33              DRMAA_PS_USER_ON_HOLD        job is queued and in user hold
34              DRMAA_PS_USER_SYSTEM_ON_HOLD job is queued and in user and system hold
35              DRMAA_PS_RUNNING             job is running
36              DRMAA_PS_SYSTEM_SUSPENDED    job is system suspended
37              DRMAA_PS_USER_SUSPENDED      job is user suspended
38              DRMAA_PS_DONE                job finished normally
39              DRMAA_PS_FAILED              job finished, but failed
40
41       Jobs'  user  hold  and  user  suspend  states  can  be  controlled  via
42       drmaa_control(3).  For affecting system hold and system suspend  states
43       the appropriate Grid Engine interfaces must be used.
44
45   drmaa_control()
46       The  drmaa_control() function applies control operations on Grid Engine
47       jobs.   jobid  may   contain   either   an   Grid   Engine   jobid   or
48       `DRMAA_JOB_IDS_SESSION_ALL'  to  refer to all jobs submitted during the
49       DRMAA session opened using drmaa_init(3).  Legal values for action  and
50       their meanings are:
51
52              DRMAA_CONTROL_SUSPEND        suspend the job
53              DRMAA_CONTROL_RESUME         resume the job,
54              DRMAA_CONTROL_HOLD           put the job on-hold
55              DRMAA_CONTROL_RELEASE        release the hold on the job
56              DRMAA_CONTROL_TERMINATE      kill the job
57
58       The  DRMAA  suspend/resume operations are equivalent to the use of `-sj
59       <jobid>' and `-usj <jobid>' options  with  Grid  Engine  qmod(1).   The
60       DRMAA  hold/release operations are equivalent to the use of Grid Engine
61       qhold(1) and qrls(1).  The DRMAA terminate operation is  equivalent  to
62       the use of Grid Engine qdel(1).  Only user hold and user suspend can be
63       controlled via drmaa_control(3).  For affecting system hold and  system
64       suspend states the appropriate Grid Engine interfaces must be used.
65

ENVIRONMENTAL VARIABLES

67       GE_ROOT        Specifies  the location of the Grid Engine standard con‐
68                      figuration files.
69
70       GE_CELL        If set, specifies the default Grid  Engine  cell  to  be
71                      used. To address a Grid Engine cell Grid Engine uses (in
72                      the order of precedence):
73
74                             The name of the cell specified in the environment
75                             variable GE_CELL, if it is set.
76
77                             The name of the default cell, i.e. default.
78
79
80       GE_DEBUG_LEVEL If set, specifies that debug information should be writ‐
81                      ten to stderr. In addition the level of detail in  which
82                      debug information is generated is defined.
83
84       GE_QMASTER_PORT
85                      If set, specifies the tcp port on which ge_qmaster(8) is
86                      expected to listen  for  communication  requests.   Most
87                      installations  will  use a services map entry instead to
88                      define that port.
89

RETURN VALUES

91       Upon successful completion, drmaa_job_ps(), and drmaa_control()  return
92       DRMAA_ERRNO_SUCCESS.   Other   values   indicate   an   error.   Up  to
93       error_diag_len characters of error  related  diagnosis  information  is
94       then provided in the buffer, error_diagnosis.
95

ERRORS

97       The drmaa_job_ps(), and drmaa_control() will fail if:
98
99   DRMAA_ERRNO_INTERNAL_ERROR
100       Unexpected or internal DRMAA error, like system call failure, etc.
101
102   DRMAA_ERRNO_DRM_COMMUNICATION_FAILURE
103       Could not contact DRM system for this request.
104
105   DRMAA_ERRNO_AUTH_FAILURE
106       The  specified request was not processed successfully due to authoriza‐
107       tion failure.
108
109   DRMAA_ERRNO_INVALID_ARGUMENT
110       The input value for an argument is invalid.
111
112   DRMAA_ERRNO_NO_ACTIVE_SESSION
113       Failed because there is no active session.
114
115   DRMAA_ERRNO_NO_MEMORY
116       Failed allocating memory.
117
118   DRMAA_ERRNO_INVALID_JOB
119       The specified job does not exist.
120
121       The drmaa_control() will fail if:
122
123   DRMAA_ERRNO_RESUME_INCONSISTENT_STATE
124       The job is not suspended. The resume request will not be processed.
125
126   DRMAA_ERRNO_SUSPEND_INCONSISTENT_STATE
127       The job is not running and thus cannot be suspended.
128
129   DRMAA_ERRNO_HOLD_INCONSISTENT_STATE
130       The job cannot be moved to a hold state.
131
132   DRMAA_ERRNO_RELEASE_INCONSISTENT_STATE
133       The job is not in a hold state.
