TOP500 machines probably have CPU features that could help with that. But yeah, afaik arbitrary precision on GPUs isn't possible with reasonable performance.

- ars 15y agoI don't think he means arbitrary precision, I think he means fixed point. And to answer him: Some programs can use it, some can't. IMO every program that can should, not not all do.
- nl 15y agoTop500 machine CPUs are usually your standard Intel or AMD CPUs[1]. In the current top 10, 5 are Intel, 4 are AMD (and 1 SPARC64). Many have Nvidia GPU co-processors. The only slightly exotic architecture in the top 10 is number 10, which supplements its AMD CPUs with Cell co-processors.
