The Potential of Science With the Cell Processor 176

prostoalex writes "High Performance Computing Newswire is running an article on a paper by computer scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory. They have evaluated the processor's performance in running several scientific application kernels, then compared this performance against other processor architectures. The full paper is available from Computer Science department at Berkeley."

Flawed AMD Chip Can Lead To Data Corruption 203

Brandonski writes "Apparently AMD allowed some flawed chips to slip through their detection grid. The problem affects only a small number of chips and only single core 2.6 and 2.8 GHz CPUs." From the article: "It is believed that the glitch is triggered when the affected chip's FPU is made to loop through a series of memory-fetch, multiplication and addition operations without any condition checks on the result of the calculations. The loop has to run over and over again for long enough to cause localized heating which together with high ambient temperatures could combine to cause the result of the operation to be recorded incorrectly, leading to data corruption."
