pvm_delhosts
DELHOSTS(3PVM) PVM Version 3.4 DELHOSTS(3PVM)
NAME
pvm_delhosts - Deletes hosts from the virtual machine.
SYNOPSIS
C int info = pvm_delhosts( char **hosts, int nhost, int *infos )
Fortran call pvmfdelhost( host, info )
PARAMETERS
hosts An array of pointers to character strings containing the names of the machines to be deleted.
nhost Integer specifying the number of hosts to be deleted.
infos Integer array of length nhost which contains the status code returned by the routine for the individual hosts. Values less than
zero indicate an error.
host Character string containing the name of the machine to be deleted.
info Integer status code returned by the routine. Values less than nhost indicate partial failure, values less than 1 indicate total
failure.
DESCRIPTION
The routine pvm_delhosts deletes the computers pointed to in hosts from the existing configuration of computers making up the virtual
machine. All PVM processes and the pvmd running on these computers are killed as the computer is deleted. If pvm_delhosts is successful,
info will be nhost. Partial success is indicated by 1<= info < nhost, and total failure by info < 1. The array infos can be checked to
determine which host caused the error.
The Fortran routine pvmfdelhost deletes a single host from the configuration with each call.
If a host fails, the PVM system will continue to function and will automatically delete this host from the virtual machine. An application
can be notified of a host failure by calling pvm_notify. It is still the responsibility of the application developer to make his applica-
tion tolerant of host failure.
EXAMPLES
C:
static char *hosts[] = {
"sparky",
"thud.cs.utk.edu",
};
int status[2];
info = pvm_delhosts( hosts, 2, status );
Fortran:
CALL PVMFDELHOST( 'azure', INFO )
ERRORS
These error conditions can be returned by pvm_delhosts
PvmBadParam
giving an invalid argument value.
PvmSysErr
local pvmd not responding.
