PCJ is a library for Java language that helps to perform parallel and distributed calculations. The current version is able to work on the multicore systems connected with the typical interconnect such as ethernet or infiniband providing users with the uniform view across nodes.
Download PCJ library (jar file of 29.02.2019 ver. 5.0.7) Latest (improved IDE support)!
Download PCJ manual (pdf) for PCJ 5 New!
The PCJ library can be used with no cost at BSD license. It requires Java 8 and no additional tools or comilers. The PCJ library for Java 7 is available in the dowload section.
The source code is available at GitHub: https://github.com/hpdcj/pcj
Version 5 introduces asyncPut() and asyncGet() methods; put() and get() methods are now synchronous. There is new handling of shared variables. The code developed for PCJ 4 hast to be modified. For details please reffer to the JavaDoc file.
