AVX Optimized App Development
Fredericx51:
Well, I do am (almost) daily looking at something interresting and/or new.
AVX, happens to be one of them ::)
I hope you'll be able to work out some usefull AVX configuration for Gauss Fit and other like triplets, pulses and spikes.
If it's usefull, I can run all 3 versions a few times, just ask cause the info might be needed(?)
And the Outage @ SETI@Home, began while I was posting :-\.
Wishing all a pleasent day, Fred.
B.t.w., when doing 2 on 1 GPU, screenlag is quite heavy, sometime all motion stops, screen no longer Refreshed.
Is ther something to change using the cmd-line parameters? (SETI Bêta rev177 (or newer, will have a look!)
Oh. boy, there might be some double attachments.(?) [Edit by Miep - I took the second instance of stderrftst_V7_J37_W32.rar out]

with OpenCL MB increase -period_iteration_num if it's laggy/ driver restarts.
with AP decrease -unroll and block sizes
I'd point you to my main post on that topic, but that's a tiny bit tricky during maintenance :)
Josef W. Segur:
Here's another test version. I've dropped the JS_AVX_b folding because that approach was a clear failure, but added JS_AVX_c folding which may do better. For the non_AVX side I did some minor cleanup, but don't expect any noticeable difference in results unless I made a typo or something.

Edit: Attachment deleted, newer version in later post.

once with boinc running, once without.

Here's the J43 run on my E8500 (5 runs with Boinc and apps running, 5 runs with Boinc and apps shut down)
