PARAMETERS

17
18       argv    An array of arguments to the executable.
19
20       args    A character string containing the arguments to the executable.
21
22       args    A character string containing the arguments to the executable.
23
24       block   Integer  specifying whether to block until startup of all hosts
25               complete or return immediately.

DESCRIPTION

31       The routine pvm_start_pvmd starts up a pvmd3 process, the master  of  a
32       new  virtual  machine.   It  returns as soon as the pvmd is started and
33       ready for work.  If the block parameter is nonzero and  a  hostfile  is
34       passed  to the pvmd as a parameter, it returns when all hosts marked to
35       start have been added.  pvm_start_pvmd returns zero on success.
36
37       If PVM is compiled to allow running more than one pvmd per host, a task
38       calling  pvm_start_pvmd  before any other pvm functions will connect to
39       the pvmd that it starts.  pvm_start_pvmd sets environment variable PVM‐
40       SOCK to the address printed by the pvmd as it starts up.
