I was able to use 13.4 under Windows 8. 13.9 broke me, and I had to do a recovery to get things working again. Have not tried 13.5-13.8.

Anybody got it working under 8.1 yet?

Nope. Have win8.1 here... can only run clLucas. I believe Bdot has told AMD of the issue(s).

I think I found workarounds for the abort and the high CPU-load issues. At least as far as I could reproduce the issues, I'm good now. After all selftests finished successfully here (halfway through), I could use volunteers to try the new version on their various driver and OS versions - who would be willing to help?

I'm still puzzled by the calculation error that make VectorSize=1 fail.

AMD still tries to reproduce the problems (i.e. run the test cases I provided) :rolleyes:

I suppose I could help test it. Windows 8.1, 13.11 beta Catalyst drivers.
