2) Message boards : Project Staging Area : PRPNet April - the dual Sierpinski problem (Message 35477)
Posted 2950 days ago by Profile Sideshow_LarryProject donor
Conan, same thing happened to me too.
One of my cores was assigned a wu that was showing up as being processed by a different person (sent out a few min earlier). I aborted my wu and was assigned a new one, which was listed properly.

Just thought I'd share... I wonder if this is happening more frequently?
It was just by chance that I individually checked the wu's assigned to the detailed stats page.


I've noticed, when I check for in-progess times on the various cores that some are not showing up in the listing. They appear to crunch normally and when they cycle through appear to be accepted when they finish.

I just figure that the next one will be OK even if this one doesn't take.

@Rroonnaalldd

@Larry
Gigabyte had in the past ever a hidden Bios menu. Try CTRL+F1 after entering the Bios...


I went back into BIOS and managed to go about 2 levels further down than I was looking previously and got to three items that seem to answer your earlier question.

item [setting]
Intel Turbo boost Tech. [AUTO]
CPU cores enabled [ALL]
CPU Multi-thread [ENABLED]
===> with a note to the side indicating that CPU hyper-threading is enabled.

So I am interpreting that as HT is enabled in the original BIOS that comes with the motherboard since I just put all the parts together and if it runs when I push the button I'm happy.

Do you really have to shut off HT? Can't you just run boinc/prpnet to use the real cores?
So if you have an i7 with 4 cores and 8 threads, set boinc to use 50% of the processors. This is what I do on my rig and I see no issues with it.


brinktastee:
I agree, since I have boinc set to 38% to get 3 cores and then was running a single instance of PRPclient.

Rroonnaalldd, even after looking in the bios setting screens at start up I can't really tell if HT is set on or off. Gigabyte seems to have a different language describing what the choices are there (at least to me). They list turbo at 29xx mhz while what I take to be normal as 2798 mhz (the xx is me not remembering what it was exactly). So even if it was kicking in the difference from 2.8 ghz to 2.9 ghz seems minimal.

Larry, was HT on or off?


I'm thinking on since I've never made any attempt to figure out how to enable/disable it. I was also running BOINC on 3 cores, but that should still have kept things so HT could kick in. In any case it was a constant since that's how I have been running both machines.

Per Rroonnaalldd's observation I ran CPU comparison to the earlier GPU tests.

CPU=i7 860 (2.8 ghz) on both machines, same motherboard.

OK, here's my 2 data points:

GTX460SE
i7-860 (2.8 gHz)
Vista-64

9999*2^458051+1 is prime! Time : 285.964 sec.

3*2^7033641+1 is prime! Time : 47063.063 sec. (Edit: Oops, ignore this one, Vista took a nap sometime overnight and I didn't notice for a while so the time is not comparable)


GTX260-192core

I ran off 5 port 12007 wu's before I figured out I needed to run the tests first and they didn't seem particularly fast around 15 minutes (IIRC) on the GTX460SE

I'm wondering how/if llrCUDA will run GFN524288 wu?

Updated to driver 260.99 seems to be working now. I'm at client 4.1.1c.

Can someone confirm that my GTX260 216 core is not a double precision capable card?
I've managed to get my GTX460SE to work but keep getting the is genefer broken error message on the 260 (Win7-64).

Oops, that should be 1.28 dollars per euro.
Sorry.

I just used paypal, had to look up euros per dollar before hand (was 1.28) but when I charged it to my credit card it was converted to dollars so I knew how much the contribution was before finalizing the transaction. Kind of far into the process to realize that the amount was more than intended but before getting into trouble because of it.
