If you are old enough to remember the time when the first distribute computers appeared on the scene, this is a deja-vu. Developers used to program on shared memory ( mostly with directives) were complaining about the new programming models ( PVM, MPL, MPI). Even today, if you have a serial code th

They hear great success stories (which in reality are often prototype implementations that do one carefully chosen benchmark well), then look at the API, look at their existing code, and postpone the start of their project until they have six months spare time for it. And we know when that is.

I was recently given a copy of "GPU Computing Gems" to review. It is basically research quality NVidia success stories, some of which are quite impressive. I got to thinking about how others are fairing (or not) with GP-GPU technology. I put up a simple poll on ClusterMonkey to help get a general
