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.
