Hi Chuck,
I found a kind of workaround. If I start the clusterServer's with info
log level turned on it seems to work fine don't ask me why need to debug
this could be a timing problem?
I executed the following in three different cygwin shells on one computer:
shell1: export OSG_LOG_LEVEL=info ; ./testClusterServer.exe -w
-g320,200,0,0 pipe0
shell2: export OSG_LOG_LEVEL=info ; ./testClusterServer.exe -w
-g320,200,320,0 pipe1
shell3: ./testClusterClient.exe -m pipe0 pipe1
Hi Marcus,
The -M option triggers creation of a MultiDisplayWindow for the cluster window
on the client. Looking at the code more carefully I
see that in testClusterClient this is the default, and so not required.
Your comment on the -m option on the servers has me puzzled, though. The
ClusterServer constructor requires a connection type,
which in testClusterServer is by default StreamSock.
yes but the server receives the connection type also from the client and
adjusts it internally.
Andreas
Thanks,
Chuck

multicast works fine with OpenSG. Most problems came form
wrong configured
networks. Some problems are:
try to set OSG_LOGLEVEL to debug and run clients and servers.

What does -M?

Remove the -m option. The client defines the kind of network
connection.

It was a test to do frame parallel renering on a ES machine.
I'm not sure
if it is still usable. I wouldn't use it.
