Integer returning machine status:

	value	MEANING
	PvmOk	host is OK
	PvmNoHost	host is not in virtual machine
	PvmHostFail	host is unreachable (and thus possibly failed)

Overview

The routine pvm_mstat returns the status mstat of the computer named host with respect to running PVM processes. This routine can be used to determine if a particular host has failed and if the virtual machine needs to be reconfigured. The function pvm_notify() can also be used to notify the caller that a host has failed.

Examples

C:
	mstat = pvm_mstat( "msr.ornl.gov" );

Fortran:
	CALL PVMFMSTAT( 'msr.ornl.gov', MSTAT )

Errors

These error conditions can be returned by pvm_mstat
