pvm_mstat - Returns the status of a host in the virtual machine.
C int mstat = pvm_mstat( char *host ) Fortran call pvmfmstat( host, mstat )
host Character string containing the host name. mstat 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)
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.
C: mstat = pvm_mstat( "msr.ornl.gov" ); Fortran: CALL PVMFMSTAT( 'msr.ornl.gov', MSTAT )
These error conditions can be returned by pvm_mstat PvmSysErr pvmd not responding. PvmNoHost giving a host name not in the virtual machine. PvmHostFail host is unreachable (and thus possibly failed).
