Description Paolo Pedroni 2010-09-24 08:23:52 UTC

Version 26.2 of sci-mathematics/gimps is available for download at the URL
above.

This is a beta for the new version. It contains mainly performance improvements. There are some minor bug fixes and features too. 
 
From the included whatsnew.txt file:
 
 1) Faster FFTs for most SSE2-capable CPU architectures.
 2) More FFT lengths supported.
 3) Some of the new, faster FFTs don't let us do as much error checking on each iteration. If you don't want to lose this error checking, choose "SUM(INPUTS) error checking" from the Options menu. This will slow down your tests by about 2-5%.
 4) When a possible hardware error occurs during a test, the error message would likely scroll off the screen unnoticed. Now, all future progress updates to the screen will be followed by a message containing a count of the errors that have occurred during the test.
 5) Worker Windows now stagger their starts. This improves timings for some
 CPUs and operating systems. See undoc.txt to control this feature.

This is not a candidate for stable (unless upstream deems it so), but it would be nice to have it in ~arch (or even package.mask'ed) for beta-testing.
