if i install windows on it i doubt i can use all the processor cores in the machine

I have a dual CPU Z800 MB that ran SETI under Win 7 with dual quad core CPUs, and with HT turned on, it happily ran 16 threads. I am sure it will work OK with dual hex core with HT turned on (24 threads). After all, HP sells them in the dual hex configuration running Windows...

well these are real 24 cores no hyperthreading 4x6 i think the real core limit on win 7 is 8 per core and a 2 socket limit

Yes, consumer versions of Windows only support up to two sockets. You would have to buy Windows Server to make use of all 4 sockets. Of course, spending $300-$600 on Windows Server probably doesn't appeal to hobbyists, so getting it to work on Linux would be your best bet on saving money.

heh i got a win server 2003 license somewhere but i see no point to slow down the machine with a completely overloaded os and a gui :)

i have to see if it is possible to gpu crunch on linux again ...i know there where some issues with it and finding a good guide is hard

I came down with a bad case of i don't give a crap

You can probably get some help here. There's some very knowledgeable Linux people on these forums. I know ML1 (Martin) is quite knowledgeable in Linux, perhaps he can help give some pointers?

I'd love to switch all my machines to linux and gpu crunch ...would make the whole thing a lot easier for me . maybe someone can chime in and maybe get something going

Windows licensing is by socket only. The number of cores per CPU is not a factor. Windows 7, any version, is limited to 2 CPU sockets. Any Standard edition of Windows Server allows up to 4 CPU sockets.
The only core limits are by platform for Windows. A 32-bit OS only supports up to 32 cores cores per CPU & a 64-bit OS supports up to 256 cores per socket.

I am surprised to hear you can't use all the cores in windows as a user here has 2 xexon machines and I'm shore he has all 24 cores running with 2 750 GPU's in them both !

yeah thats it i knew it was something around that i never cared too much about the limits since i never had a machine with more then 2 sockets

ops I was to quick Thanks Hal for the info clears that up

You can use all cores on Windows, but you are limited by the number of CPU sockets in use.

There are a few threads around here on crunching with Linux. In fact, I bought my 750Ti with Ubuntu in mind. It just made a stop in my Mac and got waylaid. Look at this machine, http://setiathome.berkeley.edu/results.php?hostid=7598775&offset=200
That looks almost identical to my Mac. He is using the App from here, setiathome_x41zc_x86_64-pc-linux-gnu_cuda60.7z
The thread, http://setiathome.berkeley.edu/forum_thread.php?id=77018

well i guess i use a 560ti and a core2 duo to try it out

My machine is not in the same league as yours but I am running SETI on a Linux (Slackware) server (Xeon E3-1230 v3) using HT with a Nvidia 750-TI GPU crunching both MBs and APs. If there is any information that I can provide, I would be glad to do so.

That would be nice i'm trying to get it running on ubuntu server 14.04
I got the parts together for a test machine and i will assemble it tomorrow

I also have a 24 core xeon machine. Comparing your APR of 9.78 GFLOPS to my hosts APR of 11.76 GFLOPS does seem that far off when you compare the CPU specs.

well i was hoping for a lil more oomph from these processors but i guess that is all i'm gonna get out of them unless i shove 7 video cards in it which brings me back to linux and gpu crunching which i think is a problem to get working if you even can get it working

if i install windows on it i doubt i can use all the processor cores in the machine

What are you using to monitor your CPUs? boincmgr (if you can get it working on your particular Linux...) will show how many jobs are running; top shows how many jobs are running and what the instantaneous CPU usage is; gkrellm will show graphs of CPU usage (I usually set mine to 300 secs history) and if you set up lm_sensors you can monitor temperatures and fan speeds, etc, as well (there's a plugin to show CPU speeds, too). gnome-system-monitor also shows individual CPU usage, but overlaid on one graph, so not ideal for a 24-core machine.

Yep I got htop cricket graphs and remote boinc manager on it
