man pvm_start_pvmd () - Starts new PVM daemon.
NAME
pvm_start_pvmd - Starts new PVM daemon.
SYNOPSIS
C int info = pvm_start_pvmd( int argc, char **argv, int block )
Fortran call pvmfstartpvmd( args, block, info )
PARAMETERS
- argc
-
Number of arguments in argv.
- argv
-
An array of arguments to the executable.
- args
-
A character string containing the arguments to the executable.
- args
-
A character string containing the arguments to the executable.
- block
-
Integer specifying whether to block until startup of all hosts complete
or return immediately.
- info
- Integer returning the error code.
DESCRIPTION
The routine pvm_start_pvmd starts up a pvmd3 process, the master of a new virtual machine. It returns as soon as the pvmd is started and ready for work. If the block parameter is nonzero and a hostfile is passed to the pvmd as a parameter, it returns when all hosts marked to start have been added. pvm_start_pvmd returns zero on success.
If PVM is compiled to allow running more than one pvmd per host, a task calling pvm_start_pvmd before any other pvm functions will connect to the pvmd that it starts. pvm_start_pvmd sets environment variable PVMSOCK to the address printed by the pvmd as it starts up.
EXAMPLES
C:
static char *argv[] = {
"-d41",
"/u/jones/pvmd_hosts",
};
argc = 2
info = pvm_start_pvmd( argc, argv, block );
Fortran:
CALL PVMFSTART_PVMD( '-d41 /u/jones/pvmd_hosts', BLOCK, INFO )
EXAMPLES
C:
static char *argv[] = {
"-d41",
"/u/jones/pvmd_hosts",
};
argc = 2
info = pvm_start_pvmd( argc, argv, block );
Fortran:
CALL PVMFSTART_PVMD( '-d41 /u/jones/pvmd_hosts', BLOCK, INFO )
ERRORS
The following error conditions can be returned
- PvmDupHost
- A pvmd is already running.
- PvmSysErr
- The local pvmd is not responding.
