As part of my focus on software performance, I also support and consult on implementing scalable parallelism in applications.
The dust of SC’11 starts to settle and several announcements around OpenMP have been made in Seattle.
Just this past week, a senior radio telescope astronomer told me about the shift from C++ back to Fortran in his corner of the world. It is all about efficiency.
Ray-tracing is a classic example of an embarrassingly parallel algorithm; since each pixel is typically independent of the rest, theoretically every pixel can be done in parallel (given enough core
The N-Body problem is a classic example used frequently to demonstrate parallelization and how it improves performance.
Most modern threading platforms are already offering task based programming models.
