AVX Optimized App Development

PatrickV2:
I will have an Ivy Bridge i7-3770 based PC (Z77 mainboard) available for a (short) while in the near future.

Is there any interest in running this benchmark/test-tool on that config?

Regards, Patrick.

Josef W. Segur:
Yes, please! The broader the range of systems tested the better. If you'd run both the J45 test attached to message 37870 and whatever the latest Chirponly version is at that time, it would be a help.

Josef W. Segur:
The FMA4 a variant produced about a 5% speedup by reducing the number of floating point instructions in the inner loop by ~11%. That's good, but confirms that getting the data transferred still needs improvement. For J51 I'm trying the TLB priming again, but without block prefetching. The i variant for AVX is modified from the h variant, and the changes were merged to the b variant for AVX+FMA4.

Edit: Attachment removed, see later post for current version
