This sort of thing is exactly what I wrote AsynCluster to do. See

Hello, I am relative new to twisted, though I have manage to make a
simple client server solution ( using perspective broker ) that I am now
try to refactor a little.
The solution is now something like :
Using perspective broker, clients connects to the server ( setting up a
remote reference to each other ).
Via a PB call, each client can request the server do some processing.
The result of the processing is distributed to each connected client -
and the client asking for the request gets a simple status report!
This solution works quite well, the only bottleneck is that all the
"thread-safe" processing on the server is done in the mainloop of the
server reactor. I want to do concurrent processing on the server!
The function doing the processing on the server, also distribute the
result to all the connected clients, and returns the result to the
klient asking for the request.
My question is :
If I just "defer" that function "toThread" ( like
threads.deferToThread( myServerProcessingFunction ) ). Do I have
potential problems, when several threads try to distribute its result to
the connecting clients???
If I have a problem:
Can I make a quick fix as follows: Within each thread ( started with
the threads.deferToThread function ), I do the distributing to the
clients by using the "reactor.callFromThread"
( like reactor.callFromThread( distributeToAllClient , myResult ) where
the function distributeToAllClient are using the remoteReference for
each client to send the "myResult" )
Or is the only solution, to let the myServerProcessingFunction returns
the "myResult" to be distributed to all connected clients, and do the
distribution in the reactor mainthread???
Thank you!
Brian
