[QUOTE=Ken_g6;286248]People over there [url=http://www.primegrid.com/forum_thread.php?id=3933]are reporting problems[/url] with the AVX build on AMD Bulldozer-based processors. Any such problems over here with 27.2?[/QUOTE]

I'm not surprised. Version 27.1 did not work on Bulldozer.

We used [URL="http://ftp//mersenne.org/gimps/source272.zip"]http://ftp//mersenne.org/gimps/source272.zip[/URL] as source and use only the gwnum-folder.
After adding [QUOTE]OBJS = cpuid.o gwnum.o gwthread.o gwutil.o gwdbldbl.o giants.o ecmstag1.o [B]gwtables.o[/B][/QUOTE] ...to the gwnum-makefile, we could compile llr- and sllr-apps with AVX-support.

27.2 on Bulldozer doesn't work for me.

I just have a strange crash while testing R207

[code]
Base factorized as : 3^2*23
Base prime factor(s) taken : 23
Resuming N+1 prime test of 22394*207^17425-1 at bit 2 [0.00%]
Using AVX Core2 type-3 FFT length 18K, Pass1=384, Pass2=48, a = 3
[/code]LLR (cmd line version) crash (tried 2 times). once the line removed, it continued to crrunch happilly( i tested the 'offending' value with pfgw)
I tested it in pfgw, and it worked.
Win 7 home premium, using a i5-2500k at stock speed
more precision : only the llr avx console version seem to crash. gui-non avx do not crash. regular 3.8.6 doesn't either.
blame it on the llravx build found on primegrid.

Regular 3.8.6 and also 3.8.7 has no AVX-support. You need at least gwnum27.2 for AVX on an Intel cpu.
Win 7 without SP1 has no AVX-support. Linux supports AVX since kernel 2.6.30, released 2009-06-09...

If anyone is running llr + gwnum v27, please stop. gwnum v27 (and v27.2 specifically) has some bugs that cause incorrect results. Until Jean releases llr + gwnum v27.4, I strongly recommend that you run with his official release.
