Messaging Middleware

Hi,

I need to exchange data between two or more process.
Each process could be on a different computer.

Is there any middleware to do this?

Actually I use RPC + message queue, I'd like something like a "remote" message queue.

I don't want to use MPI (don't ask me why...it's complex).

In alternative I can use socket...is there any higher level alternative?

Thank you
Luca

If the processes can be on different computers, then I bet the sockets are your best option.
