Java In Parallel

Zen alsory · 09-15-2009, 01:37 PM

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 how to use it ...But I'm still hesitant .
Should I use JMPI 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 .

I want to rewrite the code to be able to run (work) on my cluster .(then the code will be distributed ,and each node of the cluster will execute a certain piece of the java code ).

Hi...
I think I explained my idea well ..!
I'm asking about using MPI (Message Passing Interface )with Java like using JMPI or mpiJava ...?
I didn't talk any thing about threading ....anyway my code was built as Java Threads , but threads aren't good enough for clusters ..They are more suitable for SMP (Symmetric multi processors) .

Thank you very much ...smeezekitty
I have read about JPPF before , and i know how it works ..
But what i need is suggestions from one who has an experience ...anyway i chose mpiJava because i think it is good enough for my problem ...!
