This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Some of us have been working with multiple processors for years (SunFire T2000's at my current employer). Most Java programmers are probably writing desktop or web applications and don't need more concurrency options than threads. For that .1% that are sequencing a genome or rendering a CGI movie, I don't think it is a stretch to use Java's integral networking capabilities to stitch together a grid (though there may be better languages). It looks like the Java Parallel Processing Framework is pretty active. [ February 15, 2007: Message edited by: Joe Ess ]
