Got some benchmark data for the new Intel Woodcrest processor, running CFX 11 Preview 4 64-bit under Linux. This is for the Benchmark.def file in the installation examples directory. The CFX Community Forum has a lots of data for running this case to compare to. Serial: Total wall clock time = 1 min 33 seconds 2-way Local: Total wall clock time = 48 seconds

That's about twice as fast previous best results... nice! Stumpy

Just what I needed ... I'm designing a new cluster. Thanks for the info.

You forgot the most important thing though ... what is the clock rate of your Woodcrests?

Some details on the ram spec and motherboard used would be handy as well ...

PS: For comparison, my Opteron 275s on Linux 64 bit are almost precisely double your times.

Woodcrests are the bargain of the century considering how much cheaper they are than Opeterons.

To elaborate on the ram spec ... are your FBDIMMs in a quad channel configuration?

Have you compared the benchmark with CFX 10 on this Woodcrest? Maybe it is to ascribe partial to the new solver. But anyway very interesting.

Yes I ran it on 10. 10->11 would never result in 100% performance improvement, 5% maybe but not 100%

That's right. But on my old Smithfield with win32 there was a performance improvement of 30% from cfx10 to 11. But as I told: woodcrest benchmark is interesting at all.

Perhaps Stumps could re-run on CFX 10.

A bit more info on the system... CPU clock speed is 3.0GHz It's a 4 socket machine with 8GB RAM

Sorry, thats all - I don't have much access to this system. Stumpy

A 4 socket Woodcrest mobo? AFAIK that doesnt exist... 2 socket max.

I presume you mean 2 sockets x 2 dual core Woodcrests = 4 cores?

Yes, sorry. The OS sees 4 CPU's. I presume it's 2 dual cores. Stumpy

And how many partitions did you run?

1 and 2. The case is too small to get meaningfull results with 3 or 4 partitions.

Have you done any comparison with single-core processor?

Hi Longbow

There is extensive data on comparative benchmarks on all sorts of CPUs on the CFX Community page, under the solver discussion group.

But as Stumpy says, his reported serial speed is half the time of the previously best reported serial run (on a 3+GHz P4 with 2MB cache).

Impressive!!!

By the way, is there any comercial woodcrest workstation or cluster available now? Where can I buy one?

In my opinion the doubled cache might be an explanation for a halv solving time...
