I haven’t written about Java for some time but InfoQ has published an interesting interview with Billy Newport, distinguished engineer at IBM software group. The interview is available in video, MP3 and text transcription formats, so that it’s easy for everyone to access. It focuses on the parallel programming challenge in Java, and surveys some [...]
Last week, Microsoft shipped Visual Studio 2010. At ISTEP 2010 in Barcelona, Steve Teixera outlined some of the key features and the vision for the leading development environment. “We only ship a new release of Visual Studio every two to three years,” he said, “so it’s a big deal when we ship.” He started by [...]
Building a parallel application is, for most developers, highly reliant on the tools, libraries and other software used in the process. Even where a single company, such as Intel, is producing or involved in creating a whole range of developer technologies, it’s not always clear which is best to use. Intel is one company with a [...]
Waiting for parallel execution needs no stuff like Callbacks or WaitHandles

Thus , they are allowing developers to follow one of the eight rules for multicore programming written by James Reinders a few years ago . I’m specifically talking about rule 3 : Program in tasks chores not threads cores James suggests that you should leave the mapping of tasks to hardware threads as a distinctly separate operation in your code . When you create tasks using an efficient task based programming model , you can create as many as you can without worrying about oversubscription . Of course , you still have to pay attention to the introduced overheads . In fact , tasks also introduce an overhead and it is always important to measure . speedups Tasks consume software threads using many different techniques to
