Perpetual benchmark thread... - Page 53

4x AMD Opteron 6176 (4x 12 cores - 4x 32 Go DDR3)

http://pastebin.com/MZdGjv8A (too long to post it here)

I get every time a Segmentation fault at 8K FFT on 17 threads.
Does anyone have the same issue?

I get every time a Segmentation fault at 8K FFT on 17 threads.
Does anyone have the same issue?

Is it possible that the way the ffts are divided something as small as 8K can only be divided into <=16?
Does anything smaller work with 17 threads?

As you can see 4K, 5K and 6K worked without any problem...

Sorry I hadn't looked at the link.
The times for less than 8k seem pretty constant as if only one core is used. 8k actually slows down significantly with 16 threads. 8k is probably just the first multithreaded run(i.e. the first test with >16 cores). I would suggest pming prime95 in case he hasn't already seen this yet.

Works fine for me too, but not for the Benchmark.
I'm using a i7-3770 (4Cores+HT) with

AffinityScramble2=02461357

setting using only four cores for Prime. Hence don't touching the HT cores.
That works fine for 2 treads per test by under 10ms/Iteration for 51.5nn.nnn exponents.

But when running the benchmark, Core 1,2,5,6 are used. So 4 Threads on 2 Cores are used.
The Affinityscramble seems to [EDIT] spoil the benchmark. I'll have to comment it out to run it on core 1,,3, 5, 7.

Kyle Nov 2012 2×3² Posts	4x AMD Opteron 6176 4x AMD Opteron 6176 (4x 12 cores - 4x 32 Go DDR3) http://pastebin.com/MZdGjv8A (too long to post it here) I get every time a Segmentation fault at 8K FFT on 17 threads. Does anyone have the same issue?

henryzz Just call me Henry "David" Sep 2007 Cambridge (GMT/BST) 2×3³×109 Posts	Sorry I hadn't looked at the link. The times for less than 8k seem pretty constant as if only one core is used. 8k actually slows down significantly with 16 threads. 8k is probably just the first multithreaded run(i.e. the first test with >16 cores). I would suggest pming prime95 in case he hasn't already seen this yet.
