ADDHOSTS (3)
Add hosts to the virtual machine.
SYNOPSIS
B
C int info = pvm_addhosts( char **hosts, int nhost, int *infos )
Fortran call pvmfaddhost( host, info )
PARAMETERS
An array of strings
naming the hosts to be added.
Pvmd must already be installed and
the user must have an account on the specified hosts.
Integer specifying the length of array hosts.
Integer array of length
nhost
which returns the
status for each host.
Values less than zero indicate an error,
while positive values are TIDs of the new hosts.
Character string naming the host to be added.
Integer status code returned by the routine.
Values less than nhost indicate partial failure,
and
values less than 1 indicate total failure.
DESCRIPTION
The routine
pvm_addhosts
adds the computers named in
hosts
to the configuration of computers making up the virtual machine.
The names should have the same syntax as lines of a pvmd hostfile
(see man page for pvmd3):
A hostname followed by options of the form xx=y.
If pvm_addhosts is successful,
info
will be equal to
nhost.
Partial success is indicated by 0 < info < nhost,
and total failure by info < 1.
The array
infos
can be checked to determine which host caused the error.
The Fortran routine
pvmfaddhost
adds a single host to the configuration with each call.
info
will be 1 if successful or < 0 if error.
