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).
