: name of the hostfile describing the configuration for each host of the
12
info : integer, status code returned by the routine. Values less than
13
zero indicate an error.
16
pvm_start starts the Pvmd3 which is a daemon process which
17
coordinates unix hosts in a virtual machine. One pvmd3 must run on
18
each host in the group. They provide the communication and process
19
control functions needed by the user's PVM processes. The local and
20
remote pvmds can also be started from the PVM console program pvm. The
21
optional parameter is the name of a host file. See pvmd3 for more details
22
on the host file format. If no argument is given to pvm_start, but the
23
variable PVM_ROOT is set, scilab will try to load the file
24
$HOME/.pvmd.conf. If this file does not exist, or the variable PVM_ROOT
25
is not set, scilab will try to load the default file $SCI/.pvmd.conf. In
26
all other cases, scilab will supposed that PVM and scilab are in
27
standard place on your net. Note that, to be able to start a PVM
28
daemon, scilex must know the place to find both scilex and pvmd.
29
Normally, scilex will start a new PVM daemon by using rsh. See the help
30
on pvmd3 and pvm for more detail on how to start/stop pvm. For example:

Error -28 means: pvm_start_pvmd(): Duplicate host
