New Nehalem box installed & crunching today!

[Wiz]

The task manager looks pretty cool with the 16 processors all pegged at 100%.

It's a bit misleading though since there's two physical CPU's installed, Nehalem 5520's.
Each is quad core and HT is turned on so the system sees 16 processors, and so does Seti@Home. I've got the Win 64 AlexK loaded up for SSE 4.1 and the thing is crunching along respectably.

I'll leave it run over the weekend and see what kind of numbers it puts out over that time.

It's this one (if this works...)

Fun!

Nice one Wiz!

Number of processors 16
impressive

Looks very nice - 16WUs at a time, reasonably short crunching times - this is a great producer! Congrats! :sun:

 

[dajeepster]

what graphics card are you running?

 

[Wiz]

I haven't spent much quality time with the system yet, but it looks like an Nvidia Quadro 250 (something).

Rough numbers after a weekend - the dual Nehalem system running 16 processes is accumulating credit at about 4x the rate of my core 2 duo system.
That was with Vista Business x64 SP1. I've loaded up SP2 this morning to see if that makes any difference.
So far I am impressed, the Nehalem system has accumulated 1/4 the credit of my core 2 duo in a weekend and the core 2 system has been running for about 44 days.

Soon I will have to nuke Vista and install Windows Server 2008 R2.

oh yeah - the core 2 is 2.8 ghz running 2 processes and the Nehalem is 2.27Ghz.

Top Seti System with your processor!

Go get 'em, Wiz. :beer:

 

[Wiz]

Nice output on his rig - looks like he's got a couple video cards crunching as well?

Wonder if I can do that with the video card installed in this box?

Nvidia Quadro NVS 295

 

[petrusbroder]

Hmmm, I do not really know, but looking quickly at the drivers' specs I do not see any support for CUDA, which is a requirement for crunching e.g. seti@home with the GPU.
But I may be wrong ...

 

[Wiz]

Thanks, I will see if I can get it going. Thanks also for your other response!

 

[Wiz]

I got the driver for Vista 64 and now it's running!

Congrats! that looks very nice!

Thanks, I agree

How do you find out if it is doing any CUDA units?
Anyone here doing them?

 

[petrusbroder]

You see in BOINC-manager. In the status-column it says "0.07 CPU" and "CUDA".

 

[Wiz]

Curious as to why I could see the line about it finding a CUDA devices in the Messages area and yet was not processing any CUDA units I finally read the FAQ:

Q) Does SETI@home run GPU and CPU versions simultaneously?

No.

If BOINC determines your CPU is capable of running the CUDA version, only the CUDA version of SETI@home will run. One copy will run on each GPU you have installed. If you want to keep your CPUs occupied at the same time, you can join another BOINC project. The BOINC developers expect the capability to run CPU and GPU jobs simultaneously for the same application will be added in the next couple months.

I've already got 16 CPU processes running so I figure that's probably better than running the CUDA GPU on one card -

Agree / disagree??

Oh - I bumped it up from 2GB to 36GB memory thins morning...
