Dunnington, 24 Cores in Action

[Vinvin]

The new monster tested : http://it.anandtech.com/IT/showdoc.aspx?i=3414&p=4

It's still some problems with some applications that doesn't use more than16 threads, but they should be corrected soon ...

Hi, the article states it has six cores not twenty-four can you help me to understand, Thank you.

4 slots with one 6-core processor per slot...

So a motherboard that has for slots that can hold four 6-core CPUs, got it.

I think Windows Vista 64 recognizes each CPU individually and can handle up to 2-CPUs. So under Windows the best you can attain is 12-cores, still quite powerful, but far short of 24-cores.

Cordially,

Use Windows 2008. For some versions, good up to 64 cpus:

At 6 cores each that would give 384 threads of execution. But 8 cores will be out soon, giving 512 threads of execution. I guess that most SMP chess programs would need a special compile to handle that.

Presumably this is a Windows restriction rather than applying generally to other (more capable) operating systems.

Hmm, never seen that restriction mentioned anywhere. Vista 64 has memory limits depending on which exact version you are using (Home, Business, etc) but I don't see anything about cpus and/or cores though I assume there are some limits somewhere.

Sean is right. Vista (depending on version) limits you to 1 or 2 CPUs. If you want more than that, you need to get Windows Server 2008, which (depending on version) supports up to 64 CPUs.

Or just get a Linux version that does the same thing for a lot less cash.

Now I find it - buried in the license agreement (of course, what an obvious place to put a restriction like that). Actually Microsoft's definition is a little more generous than certain vendors (IBM) in that it doesn't treat each core as a separate CPU.

Thanks for the info.

Andy.

Looks like a half-baked hybrid...

Why not 29 Cores?
