Hey,
I'm trying to run benchmark on dula E5-2697V2 (24 physical cores / 48 HT).
Benchmark summary shows:
Intel Xeon E5-2697 v2 @ 2.70 GHz
2 processors, 24 cores, 32 threads
Why not all 48(HT) cores are being utilized?

Regards
Raf

   Hi Raf,

   I'm sorry for the delay in getting back to you.

   We're aware of an issue that causes Geekbench 3 to only run on 32 cores on systems with more than 32 cores. We're actively investigating the issue and I will let you know when we have a fix in place.

   Let me know if you have any other questions and I'd be happy to help out.

   Best,
   John

   Hello,
   Thanks for the reply. Do you have any idea when you might get this fixed?
   Do you know any other benchmarking tool ideal for high spec server?

   Regards
   Raf

   Hi Raf,

   We're hoping to have a build ready in the next week or two. The only other benchmark tools I'm aware of for servers are from SPEC and I believe they're only available in source code form.

   Best,
   John

   Hello,
   Do you have any info about ETA of the new version supporting 32+ threads?

   Hi Raf,

   We believe we've isolated the code that's causing the problem and we're working on a patch that disables the code. We should have a build ready in the next couple of days.

   Best,
   John

   Hi Raf,

   I've uploaded a build that might fix the issue you are encountering with 32+ core support. Could you download the following build and let me know how it works for you?

   http://geekbench.s3.amazonaws.com/beta/Geekbench-3.1.2-WindowsSetup...

   Thanks,
   John

    John,

    I'm having the same issue. I downloaded the version at the link you gave Raf but it didn't make any difference. Have there been any further updates?

    Thanks
    Chris

    Hi Chris,

    Unfortunately we don't have any updates at this time. We're still waiting on hardware so that we can reproduce this problem in our test lab, so for now we're limited to making educated guesses as to the source of the problem.

    I'll see if there are any other changed we can make that might address the problem. If there are, I'll post here with a link to the new build.

    Thank you for your patience.

    Best,
    John

    John,

    I have an update on this issue for you that could possibly be helpful in your efforts to troubleshoot this problem. I noticed that Adobe After Effects was having a similar issue and only using 32 of the 40 available cores. I posted the issue on the Adobe site and they found the problem for After Effects. Perhaps it is a similar issue for Geekbench. The gist of it is this:

    "Yep. There's a bug. In the code where we're querying for the number of processors, the wrong data type is being used. After Effects is using the number of slots set to 1 in a bit-field (a vector) to determine the number of cores. But the vector is being truncated at 32." - Todd Kopriva

    The full thread is here:

    Hope this helps.
