Salut Sutaru!

I use my workstation for Webmaster work. Some of my applications like Photoshop use a lot of memory and CPU.

I tried 4 cores and the mouse movement was a bit erratic and slow with my computer. With 3 cores, it's like S@H is not even running. Don't notice at all.

My computer is a low price Dell - it's nice, but not a super high ATX model.

You seem like an old pro already. Glad you found what works for you.

Thank you Hiamps.

I'm a bit confused about the various flavors of these optimized apps.

My processor supports up to SSE4.2 but I don't know how to benchmark the various differences between them so I went with SSSE3 since I have a lower-end PC with less cache than the i7 processor.

Edit: Spelling

As I remember, there is very little improvement with the sse4.2 over the ssse3 Opt-apps so you should be fine with that.

PS: watching your RAC climb every time I check in to a thread you have posted in. Will be very happy to see you zoom right on past my little machine. Don't forget to honk on the way by!

AFAIK, there is max. a SSE4.1 opt. app.

You can make a test if SSSE3x or SSE4.1 would be faster on your Core i5.
Normally the SSE4.1 app is only faster on Core2 DUO.





EDIT: BTW. The same AR can vary ~ 5 % in calculation time.

Salut Perryjay,

Don't fold the tent and go home just yet :-) I'm only running 3 cores with no CUDA. I think you may put up a pretty good fight.

I've been looking at other computers in the Statistics -> Top Computers pages to see if anyone else is using an i5 with no CUDA.

I like Intel but the top computer is an AMD and he has 1 less GPU than the #2 guy with the i7. There you go! Vyper's got over 8,400 WUs on that 1 computer!

Vyper had 4x GTX295 in his PC case.
The RAC is decreasing since he took one and now two GTX295 out of his box.

The first two AMDs in the top_host_list crunching only CUDA. Nothing on the CPU for max. GPU performance.

Hi Niko.
I'm on the Intel side also... you can't beat a Core i7!. Never really tried AMD enough to like it.

Just be careful with the GPU column in the statistics page. There is a slight mishap/bug at the moment which displays the main card in the column only, i.e. someone could be running 1x GTX295 and 3x GT8800. And if the main "default" card is set as the GTX295, it will display as 5x GTX295 (because of the 3x 8800GT & the GTX295 which is actually 2 GPUs, as Fred and Sutaru kindly pointed out... thanks guys ;), while in reality, it isn't that simple!

Also, welcome to S@H... :)

... it will display as 4x GTX295, while in reality, it isn't that simple!

It would actually report as 5 x GTX295 since the 295 has 2 GPU's.

Then it would displayed 5x GTX295..

1x GTX295 -> 2 GPUs


The top_host_#2 have 2x GTX295 and 1x GTX260-192

EDIT: Fred W was faster..

It also takes Vyper 10 days to get around to doing a workunit. I'm waiting on two or three with him as my wingman! :-)

Sutaru,
I have a similar setup to your smaller machine, but I'm stuck at 8500/9000 rac. This machine is only used for email or occasional web searches, so its not stressed at all. I'm running the optimized apps, CUDA 191 with 2.3 dlls. Am pulling my hair out to get this one crunching faster. I also have another machine i7-860 with gtx 275 that is only approaching 10000 rac. These both appear to be only 50% of their capacity.

Alex, you let run your CPUs/GPUs at stock speed or you overclock?

The Core i7 860 @ 3.36 GHz ?
GTX275 @ 1575 MHz shader ?
..both OCed.

The Q9300 @ 2.50 GHz ?
GTX260-216 @ 1485.862 MHz shader ? (little strange, normally the last three are 000)
Only GPU OCed.

Correct?


The CUDA calculation time of the GTX260 look well.
The GTX275 look little bit slow, compared to your GTX260.
Maybe because of the other CPU. Don't know. I guess you would see faster GTX275 if you let run only 4 threads on Core i7 (HT off).

~ same AR WU:
GTX260:
[http://setiathome.berkeley.edu/result.php?resultid=1440998936]
Run time 651.90625
CPU time 58.79688

GTX275:
[http://setiathome.berkeley.edu/result.php?resultid=1450438967]
Run time 907.875
CPU time 259.3594


For a stable RAC you need to let run the PCs 24 hours/day and around 1 month.
They are online like this?

You let run TThrottle, or let one CPU-Core idle?
8x CPU (Core i7) and 4x CPU (Q9300) tasks?

Also you could look if the SSSE3x or the SSE4.1 app is faster on your PCs.
If Core i7 OCed, I guess SSSE3x is faster.
Q9300 @ stock, then maybe SSE4.1 .


Other can also jump in for their experiences, opinions..

If nVIDIA_driver_190.38 the GPU shader speed isn't correct detected/shown with opt._MB_6.08_CUDA_V12_app.
(+ ~ 6 - 12 MHz)

There are two reasons *not* to run the optimized applications:

1) Availability. Some machines do not run optimized applications well (or at all).

2) Responsibility. If you load an optimized application, you have to watch to make sure you manually update it when the "stock" application is updated.

For the hundreds of thousands of crunchers who are producing useful work, but don't frequent the forums, #2 represents a lot of dedication.

Especially if they have a bunch of machines.

... and yes, I do run optimized apps.

---

So why not to make BOINC smart?
That the client can update (DL) the (full) opt. apps automatically?

Maybe if not with automatically CPU-Z function.
Then maybe with some buttons (MMX, SSE, SSE2..) for to choose the extensions of the CPU.

---

seti/boinc allows the 3rd party apps. However they are 3rd party apps and Seti would be required to write more code so that the proper apps got to the proper machines SSE SSE2 SSE3 etc would all have to be coded in and then you'd have to hope that seti sent you the correct app. This would be a very low priority considering all thats been going on.
