Well, it's clear that the software prefetching is doing some good though not clear why the more distant prefetch works slightly better on the 8 core Bulldozers even when BOINC is active. Getting those details pinned down can wait for final tuning though.

With AVX chirping times at ~80% of SSE3 chirping on Bulldozer but ~50% on Sandy Bridge, I'm looking for something with larger effects. One faint possibility is that the way the input and output test buffers are allocated in J48 and earlier might possibly cause L1 cache thrashing. I don't think that's likely, but am attaching J48a. The allocations are revised but functions being tested are unchanged.

Edit: Attachment removed, see later posts for current test.

Thanks, it's good to be sure the test allocations weren't causing the problem.

For J49 I've collapsed the f subvariants back to a single with the same prefetch as a through e (4 cache lines ahead). Even though that may not be the best, it makes comparison easier.

Added test g, which loads data in two 128 bit chunks rather than full 256 bit chunks. That's a technique some Intel documents recommend, though it's not expected to make a large difference.

Added test h, which does TLB priming to eliminate delays crossing page boundaries, and prefetches a whole page sized block at once, like the Astropulse TWINDECHIRP. I have hopes that might make a significant difference.

The sse3_ChirpData_ak8 variant didn't have prefetch, so was often slower than sse2_ChirpData_ak8. I've put the prefetch in.

Although I've reviewed the changes to the AVX routines several times, they're significant enough there's some risk of crashing if I missed something. I hope not.

Indeed not, and these ~2% differences simply prove I haven't yet found what I'm looking for. Having the h test go the wrong way may be more revealing if I can correlate it with BD features.

Trying to find the strengths of Bulldozer, I've added a chirp variant using both AVX and FMA4 in J50. It does reduce the number of instructions in the loop by 8 or more so should have some measurable effect, though it still has to load and save just as much data. Other than the FMA4 changes, it's like the g AVX version.

If I have everything right, it ought to show as unsupported on Sandy Bridge and run on Bulldozer. If not, anything might happen.
