Is there any library for distributed in-memory cache, distributed tasks, publish/subscribe messaging? I have used Hazelcast in Java, I would like something similar.
I know that Memcached is an in-memory cache and even distributed, but it is missing the messaging and remote task.
I just need something to coordinate a cluster of server without using traditional RPC and socket programming.
MPI might be what you want: http://en.wikipedia.org/wiki/Message_Passing_Interface
There are C++ hooks available in boost: http://www.boost.org/doc/libs/1_39_0/doc/html/mpi.html
Here is an informative podcast about Open-MPI, which is an implementation of MPI: http://twit.tv/floss50
