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 )

ERRORS

       The following error conditions can be returned

       PvmDupHost
              A pvmd is already running.

       PvmSysErr
              The local pvmd is not responding.
