29.2 benchmark help

The windows version is complaining about a missing file "libhwloc-5.dll". It is included with the 29.1 version:
ftp://ftp.mersenne.org/gimps/p95v291.win64.zip

I'm still using 28.9, so I did not realize at first that the dll files comes with 29.x versions.

I did one already and e-mailed it. I'll also attach it to this post.

It's good that you're also doing one, though, because the data seemed a bit puzzling (to me at least), so it will be good to have a second benchmark and see if the results are consistent and reproducible.

In practice, as mentioned, the c4.large is much more relevant. I think it's worth running a separate benchmark for that too. Of course a c4.large shares a physical server with other Amazon customers, so 8 seconds might not be long enough to even out short-term effects.

Maybe the coffee hasn't kicked in yet, but I got results overnight and I can't see where to e-mail results?

For now, they're attached to this post.

3 results included:
E5-2683 v3 ES at 2.3 GHz all cores active, 2133 quad channel, single rank ram. HT was turned off.
Ryzen 1700 stock (3.2 GHz all cores active), 2666 dual channel, single rank ram. SMT on but not tested.
i5-6600k @ 4.2 GHz, 3000 dual channel, 2 rank ram. No HT.

More will follow as I switch from existing jobs.

It seems that your output format is different from mine. I'm not sure how to compare the results.

I just had mprime and prime.txt with 1 line (AllBench=1) in the folder, and I chose options 16 in the menu "Options/Benchmark" and then:

0 (for Throughput)
16
32768
Y (every FFT size)
N (1 core)
Y (all cores)
N (core combinations)
N (hyperthreading)
Y (1 worker)
Y (maximum workers)
N (worker combinations)
8 (seconds)
Y (accept answers)

Sounds the same as what I did, except I also chose to do every number of workers between 1 and maximum (1, 2, 3, .. 18). It ended up taking about 15 hours. I think the 2-worker case is pretty important here.

I also used the special executable George linked in this thread. You can get it on Linux using wget on the URL. Did you by any chance use the regular executable instead, or version 28?

wget -O mprime "https://www.dropbox.com/s/9n3cfkumuqykbbp/mprime?dl=0"
chmod +x mprime

Thanks all!!! I've got a lot of data to digest over the next few days.

I used the special 29.2 mprime. Mine took 14h15m for just 1 + all workers, so yours must have taken a lot longer than 15 hours.

Intel Ark doesn't list that CPU, apparently Intel only sells it to Amazon?
10 cores with such high frequency is rare to find on Xeons.

Yes, it's special for Amazon. Intel was willing to spec it with high clocks because Amazon could guarantee appropriate cooling.
