pvm_halt Scilab // Group Scilab function pvm_halt
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
