On of the things with the C set is they didn't use Intel's icc. On our main application (which involved a lot of heavy duty number crunching) it speeds up our application by 100% over the best we can get out gcc.
- fnord123 9y agoI've seen 20% speedups with icc over gcc; but not a doubling. Is this including mkl over some other numeric library as well?
- danieltillett 9y agoNo nothing extra. The code does vectorise well. But even if the result is 20%, it would make quite a bit of difference to the results presented in this paper.
