Intel® Parallel Studio Service Pack 1 is now available, adding support for Windows* 7. SP1 is well worth downloading and installing - here are some of the reasons: Parallel Inspector and Parallel Amplifier can be driven (for automating test suites) from the command line now. Bug fixes - of course - not many issues needed fixing, but you [...]

Once again I would like to discuss the issue of using magic constants in code. We can eternally repeat that one should use sizeof() operator for correct calculation of the size of memory being allocated. But both this knowledge and correct writing of a new code will not help you detect an error already existing in the maze of the old code in large projects.

This morning, I took a rare break, and attended a tutorial at Supercomputing.  I'm glad I did. The tutorial looked at the pros and cons of mixing MPI and OpenMP in a single program, and was taught by Rolf Rabenseifner (University of Stuttgart), Georg Hager (University of Erlangen) and Gabriele Jost (Texas Advanced Computing Center/Naval Postgraduate School). Not too [...]

During his tech session on Wednesday at Microsoft Tech-Ed Europe 2009 Rami Radi from Intel showed a very compelling demonstration how Intel's sampling and profiling tool VTune Performance Analyzer can help .NET developers to multi-thread their applications in order to make them run faster on multicore machines. So we asked Rami to show us this [...]

The first session during Day Four at Microsoft Tech-Ed Europe 2009 was held by Ralf Westphal, a German software developer, speaker, expert, whatever. He is a real good guy who knows a lot about (parallel) programming topics. So it was no surprise that he talked about asynchronous parallel programming in a very lively and comprehensive manner.  His [...]

Now I know at least what "Birds-of-a-feather" discussion means: many interested people come together in a medium sized room, listening to a well-educated guy talking about his favorite topic. And right after the start of the session there is a lively discussion going on where you hear a lot of new and some known things. That's [...]
