1) Message boards : Number crunching : Can't change computing preferences (Message 970208) Posted 13 Feb 2010 by A-D Post: I couldn't see any local preferences to change, but hadn't tried the "Clear" function. That appears to have done it. Thanks.

2) Message boards : Number crunching : Can't change computing preferences (Message 970192) Posted 13 Feb 2010 by A-D Post: Nothing seems to happen when I change my computing preferences on the SETI website and then update BOINC. I've been fiddling with the "number of processors," "percent of processors," and "percent of time" settings. No matter what I set these to, BOINC always runs all cores/threads, 100%. I have an i7 CPU and run the optimized apps.

3) Message boards : Number crunching : How hot do you let your i7 get? (Message 963934) Posted 16 Jan 2010 by A-D Post: Until it dies.................. Was this directed at me? Why am I any more likely to kill my CPU than anyone else here? I don't even overclock (other than the TurboBoost thing), and have been quite aggressive at keeping my temps down.

4) Message boards : Number crunching : How hot do you let your i7 get? (Message 963895) Posted 16 Jan 2010 by A-D Post: I run my i7 860 at 100%, all cores, with both HT and TurboBoost (= 2.94Gz). RealTemp reports my core temps range from mid-40s to low 50s. Cooling: case completely open and upside down (CPU on bottom); PSU outside case; Thermalright Ultra 120 Extreme (w/LGA1156 adapter) with two 120mm Noctua fans at ~800rpm.[/img]

7) Questions and Answers : GPU applications : Quadro NVS as dedicated CUDA card? (Message 932039) Posted 9 Sep 2009 by A-D Post: A separate question, obviously, would be whether this card could do enough to make it worth the trouble...

8) Questions and Answers : GPU applications : Quadro NVS as dedicated CUDA card? (Message 932017) Posted 9 Sep 2009 by A-D Post: This may be a stupid question for any number of reasons. I have a GTS 250, which I use because it's the best card that can be (practically) passively cooled. I'm looking at the PCI-E x1 slots on my board and wondering: what would happen if I stuck an NVS 295 in there -- as in, not connected to any display, just there as a co-processor? Does anyone know if this would work? Would BOINC just see this as another CUDA device available for crunching? Would it screw up anything in Windows?

9) Questions and Answers : Windows : Should i get a Quadro (workstation) card. (Message 931984) Posted 8 Sep 2009 by A-D Post: I'm wondering about this too, but for an additional dedicated CUDA card, not for graphics. I have a GTS 250. Could I stick an NVS 295 into a PCI-Ex1 slot and have it available just for BOINC? The card has only 256MB memory, but then that would not have to be shared with graphics. I'm sure there's some reason why this wouldn't work.

10) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 931363) Posted 6 Sep 2009 by A-D Post: The heatsink is a Thermalright Ultra 120 Extreme. I'll do the razor blade test when I next have the system apart. Assuming the base looks fine, I'll turn the heatsink 180 degrees and note whether anything changes.

11) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 931024) Posted 4 Sep 2009 by A-D Post: My concern wasn't so much the absolute magnitude of my temps, even that of Core 0. It was the 7 degree disparity I was wondering about. I was interested in setting BOINC to use three cores regardless, in part so I might back off on my fan RPMs a bit, and I just figured that if there were a way to force BOINC always to use Cores 1-3 and not 0, that would be the thing to do.

12) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 931017) Posted 4 Sep 2009 by A-D Post: Ah, there we go. I didn't realize what "Affinity" was. So now I have Cores 1-3 at max and Core 0 idling. I think something may be screwy with the Core 0 sensor, since it now shows Cores 0, 2, and 3 about the same, and Core 1 a few degrees cooler. So Core 0 is the same temp idling that the others are at max. I'll re-seat the heatsink next week anyway, but surely I have a sensor anomaly. Edit: Cores 0, 2, and 3 at about 55. Core 1 at about 51. Edit 2: Core 0 would be around 60 if it were at max.

13) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 931006) Posted 4 Sep 2009 by A-D Post: That is weird. I changed Preference to use 25% of processors. I have one WU crunching, but Task Manager shows all cores busy and no one core at max. Core 0 is at about 60%, and Cores 1-3 are at about 15%. Not surprisingly Core 0 still shows several degrees hotter than the others. zpm above seemed to indicate there was a way to force a core assignment "manually." Unless I misunderstood. I still see no way to do this.

14) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 930989) Posted 4 Sep 2009 by A-D Post: I'm going to do that next week when I install a new PSU. However, the rig is quite new. I spent a great deal of time lapping the base of my heatsink, and use Tuniq TX-2 thermal grease, so this is irritating. I don't have the courage to lap the CPU heat-spreader.

15) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 930974) Posted 4 Sep 2009 by A-D Post: Thanks. I would be interested to see what if any difference it makes. I cannot see even how to set this manually in Task Manager. It shows core usage. There is an option for shifting tasks among the cores?

16) Message boards : Number crunching : Any way to control which cores BOINC uses? (Message 930967) Posted 4 Sep 2009 by A-D Post: Using RealTemp with my Q9550. It consistently reports Core 0 to be about 7 degress hotter than Cores 1-3. I changed the "use ___% of processors" option in Preferences to 75%. It began using Cores 0, 1, and 3. Does anyone know any way I can specifically instruct BOINC to use Cores 1-3 and not Core 0?

18) Message boards : Number crunching : CLOSED (Message 274752) Posted 3 Apr 2006 by A-D Post: Personally I feel that it should not stop at $750,000 or March next year we will be faced with the same issue... Uh, well, they are calling this an "annual fundraising drive," and the e-mail says that "we will need to raise about $750,000 to pay for these new capabilities and to keep SETI@home operating for the next year." It sounds as though the project will be in perpetual fundraising mode unless it finds some serious backers. Or am I missing something?

19) Questions and Answers : Windows : BOINC / S@H on a 64-bit machine? (Message 81300) Posted 20 Feb 2005 by A-D Post: > As far as I know there isn't one in 64-bit!

I am in the process of upgrading to Windows X64 with an Athlon64, too. I get the impression that running in 64 bits would make more of a difference for some BOINC projects than for others, but I'm very anxious to see what those differences are. There must be an increasing number of people with 64-bit processors running 64-bit operating systems. So I have a couple questions: 1) Is it just BOINC for which a 64-bit version has to be developed, or each BOINC project (I run them all), or both? 2) I haven't the faintest idea how to compile my own versions for 64-bit operation. Surely there must be 64-bit releases in the works by now, no? Has anyone heard anything?
