pbsdsh - distribute task to nodes under pbs
pbsdsh [-c copies] [-o] [-s] [-u] [-v] program [args]
pbsdsh [-n node] [-o] [-s] [-u] [-v] program [args]
pbsdsh [-h nodename] [-o] [-v] program [args]
Executes (spawns) a normal Unix program on one or more nodes under control of
the Portable Batch System, PBS. Pbsdsh uses the Task Manager
API, see tm_spawn(3), to distribute the program on the allocated nodes.
When run without the -c or the -n option, pbsdsh will spawn the program
on all nodes allocated to the PBS job. The spawns take place concurrently -
all execute at (about) the same time.
Users will find the
PBS_NODENUM , and the
PBS_VNODENUM environmental variables useful. They contain the TM task id, the node
identifier, and the cpu (virtual node) identifier.
The program is spawned on the first
nodes allocated. This option is mutual exclusive with -n.
The program is spawned on one node which is the
node allocted. This option is mutual exclusive with -c.
The program is spawned on the node specified.
Capture stdout of the spawned program. Normally stdout goes to the jobs output.
If this option is given, the program is run in turn on each
node, one after the other.
The program is run once on each node (unique). This ignores the number
of allocated processers on a given node.
Verbose output about error conditions and task exit status is produced.
The first operand,
is the program to execute.
are passed as arguments to the program.
The pbsdsh command will write a diagnostic message to standard error for
each error occurrence.
Upon successful processing of all the operands presented to the command, the
exit status will be a value of zero.
If the pbsdsh command fails to process any operand, or fails to contact the
MOM daemon on the localhost the command exits with a value greater than zero.
