parallel processing with JAVA

Question

I have a project and the task of the project is implementing matrix multiplication in respective parallel distributed environment (at least on 2 computers). I want to solve my problem in JAVA. There is no problem with matrix multiplication, just don't know which technology to use for running it in parallel distributed environment. What do you suggest? Thanx :)

Answer 1

The Akka actor library has excellent support for remote actors which transparently handle data serialization. If you can decompose your matrix multiplication to use actors, you can then later configure your actors to run in the distributed environment quite easily using Akka.

Answer 2

Hadoop is one of most widely used distributed computing tool. Though your computing requirement is not very intensive, its a good good tool to explore.

Answer 3

I've worked with Hazelcast before. Very easy and straightforward. Just be careful with parallel processing. The job needs to be big enough with a small data footprint, else you're going to be tied down by network communication.

i.e. multiplying matrices may be faster on a sinlge processor; but a hard genetic algorithm works great as each cpu can be an island as a islandic ga implementation. Network communication will be limited to emigration strategies.

good luck!
