Sun Grid Engineを使用して、サブミットスクリプトqsub内のマスターノードでコマンドを実行する方法はありますか？ qsubスクリプト内から/bin/hostnameを実行した場合、私はすでにマスターノードではなくキューコンピュータの1台にいます。要するに、私はちょうど私がちょうど自動的に提出した仕事にqstatを実行したいです。 qstatをワーカーノードの1つとして実行しようとすると、ワーカーノードが送信または管理ホストではないというエラーメッセージが表示されます。qsubサブミットスクリプトからマスターノードでコマンドを実行する
私はqsubスクリプトの外からこれを行うことができるとわかりましたが、スクリプトはジョブ名やsgeジョブIDなどの多くの有用な変数を定義しています。
クライアントコマンドは、ジョブが実行されているノードからアクセスできる必要があります。 qstatへのフルパスを入力してみてください。ヘッドノードにある場所と一致する可能性があります。見つからなければ、計算ノードにインストールするか、管理者に依頼してください。
編集：一部の管理者は、 "qstatスパム"が十分なシステムでサーバーに過負荷を与える可能性があるため、これを許可したくありません。 がに電話できる場合は、数秒ごとに呼び出すのではなく、丁寧に考えてください。
提出されたジョブの詳細を取得するだけであれば、送信するクライアントによって提供される環境変数を使用する方がよい場合があります。 qsubのマニュアルページ（man qsub）の環境変数セクションを参照してください：
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 address a Sun Grid Engine cell qsub,
qsh, qlogin or qalter use (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 com-
munication requests. Most installations will
use a services map entry for the service
"sge_qmaster" instead to define that port.
DISPLAY For qsh jobs the DISPLAY has to be specified
at job submission. If the DISPLAY is not set
by using the -display or the -v switch, the
contents of the DISPLAY environment variable
are used as default.
In addition to those environment variables specified to be
exported to the job via the -v or the -V option (see above)
qsub, qsh, and qlogin add the following variables with the
indicated values to the variable list:
SGE_O_HOME the home directory of the submitting client.
SGE_O_HOST the name of the host on which the submitting
client is running.
SGE_O_LOGNAME the LOGNAME of the submitting client.
SGE_O_MAIL the MAIL of the submitting client. This is
the mail directory of the submitting client.
SGE_O_PATH the executable search path of the submitting
client.
SGE_O_SHELL the SHELL of the submitting client.
SGE_O_TZ the time zone of the submitting client.
SGE_O_WORKDIR the absolute path of the current working
directory of the submitting client.
Furthermore, Sun Grid Engine sets additional variables into
the job's environment, as listed below.
ARC
SGE_ARCH The Sun Grid Engine architecture name of the
node on which the job is running. The name is
compiled-in into the sge_execd(8) binary.
SGE_CKPT_ENV Specifies the checkpointing environment (as
selected with the -ckpt option) under which a
checkpointing job executes. Only set for
checkpointing jobs.
SGE_CKPT_DIR Only set for checkpointing jobs. Contains
path ckpt_dir (see checkpoint(5) ) of the
checkpoint interface.
SGE_STDERR_PATH
the pathname of the file to which the stan-
dard error stream of the job is diverted.
Commonly used for enhancing the output with
error messages from prolog, epilog, parallel
environment start/stop or checkpointing
scripts.
SGE_STDOUT_PATH
the pathname of the file to which the stan-
dard output stream of the job is diverted.
Commonly used for enhancing the output with
messages from prolog, epilog, parallel
environment start/stop or checkpointing
scripts.
SGE_STDIN_PATH the pathname of the file from which the stan-
dard input stream of the job is taken. This
variable might be used in combination with
SGE_O_HOST in prolog/epilog scripts to
transfer the input file from the submit to
the execution host.
SGE_JOB_SPOOL_DIR
The directory used by sge_shepherd(8) to
store job related data during job execution.
This directory is owned by root or by a Sun
Grid Engine administrative account and com-
monly is not open for read or write access to
regular users.
SGE_TASK_ID The index number of the current array job
task (see -t option above). This is an unique
number in each array job and can be used to
reference different input data records, for
example. This environment variable is set to
"undefined" for non-array jobs. It is possi-
ble to change the predefined value of this
variable with -v or -V (see options above).
SGE_TASK_FIRST The index number of the first array job task
(see -t option above). It is possible to
change the predefined value of this variable
with -v or -V (see options above).
SGE_TASK_LAST The index number of the last array job task
(see -t option above). It is possible to
change the predefined value of this variable
with -v or -V (see options above).
SGE_TASK_STEPSIZE
The step size of the array job specification
(see -t option above). It is possible to
change the predefined value of this variable
with -v or -V (see options above).
ENVIRONMENT The ENVIRONMENT variable is set to BATCH to
identify that the job is being executed under
Sun Grid Engine control.
HOME The user's home directory path from the
passwd(5) file.
HOSTNAME The hostname of the node on which the job is
running.
JOB_ID A unique identifier assigned by the
sge_qmaster(8) when the job was submitted.
The job ID is a decimal integer in the range
1 to 99999.
JOB_NAME The job name. For batch jobs or jobs submit-
ted by qrsh with a command, the job name is
built as basename of the qsub script filename
resp. the qrsh command. For interactive jobs
it is set to `INTERACTIVE' for qsh jobs,
`QLOGIN' for qlogin jobs and `QRLOGIN' for
qrsh jobs without a command.
This default may be overwritten by the -N.
option.
JOB_SCRIPT The path to the job script which is executed.
The value can not be overwritten by the -v or
-V option.
LOGNAME The user's login name from the passwd(5)
file.
NHOSTS The number of hosts in use by a parallel job.
NQUEUES The number of queues allocated for the job
(always 1 for serial jobs).
NSLOTS The number of queue slots in use by a paral-
lel job.
PATH A default shell search path of:
/usr/local/bin:/usr/ucb:/bin:/usr/bin
SGE_BINARY_PATH
The path where the Sun Grid Engine binaries
are installed. The value is the concatenation
of the cluster configuration value
binary_path and the architecture name
$SGE_ARCH environment variable.
PE The parallel environment under which the job
executes (for parallel jobs only).
PE_HOSTFILE The path of a file containing the definition
of the virtual parallel machine assigned to a
parallel job by Sun Grid Engine. See the
description of the $pe_hostfile parameter in
sge_pe(5) for details on the format of this
file. The environment variable is only avail-
able for parallel jobs.
QUEUE The name of the cluster queue in which the
job is running.
REQUEST Available for batch jobs only.
The request name of a job as specified with
the -N switch (see above) or taken as the
name of the job script file.
RESTARTED This variable is set to 1 if a job was res-
tarted either after a system crash or after a
migration in case of a checkpointing job. The
variable has the value 0 otherwise.
SHELL The user's login shell from the passwd(5)
file. Note: This is not necessarily the shell
in use for the job.
TMPDIR The absolute path to the job's temporary
working directory.
TMP The same as TMPDIR; provided for compatibil-
ity with NQS.
TZ The time zone variable imported from
sge_execd(8) if set.
USER The user's login name from the passwd(5)
file.
SGE_JSV_TIMEOUT
If the response time of the client JSV is
greater than this timeout value, then the JSV
will attempt to be re-started. The default
value is 10 seconds, and this value must be
greater than 0. If the timeout has been
reached, the JSV will only try to re-start
once, if the timeout is reached again an
error will occur.
