pvm_halt(1) Scilab function pvm_halt(1)
NAME
pvm_halt - stops the PVM daemon
CALLING SEQUENCE
[info] = pvm_halt()
PARAMETERS
info : integer, status code returned by the routine. Values less than zero
indicate an error.
DESCRIPTION
pvm_halt kills all PVM tasks, all the remote daemons, and the local daemon.
If the master pvmd is killed manually it should be sent a SIGTERM signal to
allow it to kill the remote pvmds and clean up various files.
The pvmd can be killed in a manner that leaves the file /tmp/pvmd.uid
behind on one or more hosts. Uid is the numeric user ID (from
/etc/passwd) of the user. This will prevent PVM from restarting on that
host. Deletion of this file will fix this problem:
rm `( grep $user /etc/passwd || ypmatch $user passwd )
| awk -F: '{print "/tmp/pvmd."$3; exit}'`
For example:
-->pvm_halt()
ans =
0.
-->pvm_halt()
ans =
- 14.
Error -14 means: pvm_halt(): Can't contact local daemon
