NAME

pvm_mstat - Returns the status of a host in the virtual machine.

SYNOPSIS

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)

DISCUSSION

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
PvmSysErr
pvmd not responding.
PvmNoHost
giving a host name not in the virtual machine.
PvmHostFail
host is unreachable (and thus possibly failed).
