Parallel programming in Java

Question

How can we do Parallel Programming in Java? Is there any special framework for that? How can we make the stuff work?

I will tell you guys what I need, think that I devel

Answer 1

You might try Parallel Java 2 Library.

Fast forward to 2013, when I started developing PJ2. Parallel computing had expanded far beyond what it was a decade earlier. Multicore parallel computers were equipped with many more CPU cores and much larger main memory, such that computations that used to require a whole cluster now could be done on a single multicore node. New kinds of parallel computing hardware had become commonplace, notably graphics processing unit (GPU) accelerators. Cloud computing services, such as Amazon's EC2, allowed anyone to run parallel programs on a virtual supercomputer with thousands of cores. New application areas for parallel computing had opened up, notably big data analytics. New parallel programming APIs had arisen, such as OpenCL and NVIDIA Corporation's CUDA for GPU parallel programming, and map-reduce frameworks like Apache's Hadoop for big data computing. To explore and take advantage of all these trends, I decided that a completely new Parallel Java 2 Library was needed.

In early 2013 when PJ2 wasn't yet available (although an earlier version was), I tried Java Parallel Processing Framework (JPPF). JPPF was okay but at first glance PJ2 looks interesting.
