Signaling

  • int pvm_sendsig( int tid, int signum )

Sends a signal to one more PVM process. tid is task identifier of PVM process to receive the signal. The signum is the signal number.

  • int info = pvm_notify( int what, int msgtag, int cnt, int *tids )

PvmTaskExit

Task killed or is exits.

PvmHostDelete

Host is crashes or deleted.

PvmHostAdd

msgtag is message tag to be used in notification. cnt For PvmTaskExit and PvmHostDelete, states the length of the tids array. For PvmHostAdd states the number of times to notify.
