Java In Parallel

[Z-hh]

Hello All...
I have a Java Application and i want to run it in parallel .
I have a beowufl cluster consists of 5 computers with fedora 11 and I use MPICH2 for C/C++ programs .
I have read about JMPI and mpiJava and how to use them ...But I'm still hesitant .
Should I use JMPI or mpiJava or I have to think about others ways like JPPF ,RMI,.......?
I need your help to decide ...
I'm looking for your suggestions and your replies .

All depends I think. If you have and EJB application, jboss has built in support for distributed loads. For other application types, I ever used communication via sockets, is clean, simple and efficient but not transparent.

Perhaps you could use Threads in your application?

Hi..
Jamwa:
My code was built as Java Threads , but Java threads aren't good enough for clusters ..They are more suitable for SMP.

What do you mean by sockets ?? I don't know how to use sockets ...!
Thanks ...

Sockets is part of java.net package. You can learn with documentation from sun site. Sockets is a way of communication between applications using streaming. You can exchange data between applications while running. Not much sophisticated but is simple and worked fine for me at least with 2 machines running in parallel.
