[Spread-users] Spread Configuration

[Wangbong Lee]

If you ran a daemon on every computer that had clients, then a clients send 
would translate to a single reliable broad/multicast sent between the
daemons. 
   All the client communication would be contained within the machines.

What do you mean by that?
You mean that the clients have to communicate each daemon for distributed
computing 
instead of connecting one daemon in its machine ?
Other question, is it possible to communicate between daemons ?

Thanks,

In general, running more daemons, so long as they are properly configured,
will 
increase performance.  Usually you should run a spread daemon on each of the

computers that will host client applications and have the clients connect to

their local daemon.  In the configuration file, all of the daemons that can 
communicate using 1-hop broad/multicast (e.g. - within a LAN) should be
listed 
in the same segment.

If you were to run a single daemon in a site and have clients connect
remotely 
to the daemon (say all join the same group), then each time a client sent a 
message it would translate into N + 1 unicasts of that message -- once to
the 
daemon and N times back to the clients.

If you ran a daemon on every computer that had clients, then a clients send 
would translate to a single reliable broad/multicast sent between the
daemons. 
   All the client communication would be contained within the machines.

Cheers!
