NAME
pvm_mstat - Returns the status of a host in the virtual machine.
SYNOPSIS
C int mstat = pvm_mstat( char *host )
Fortran call pvmfmstat( host, mstat )
PARAMETERS
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)
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).
