21) Questions and Answers : GPU applications : Why does a GPU uses more FLOPS then a CPU, for the same job? (Message 984636) Posted 28 Mar 2010 by popandbob Post: I believe the reason behind it is the CPU can do some calculations in a single calculation which the GPU has to do in a couple. It would be like asking the CPU to do 2x2 it would figure it out with one calculation of 2x2=4 where as the GPU would have to 2x2= 2 groups of 2 means 2+2=4 (2 calculations) That's obviously not a true case but I'm sure you get the idea.

Do you think you could get around to it sometime? Cheers, Bob

24) Message boards : Number crunching : New feature request...New Button (Message 982210) Posted 21 Mar 2010 by popandbob Post: It would also help other projects because you could tell boinc to not try and get GPU work from a project which doesn't have a GPU app. Bob

You only receive other emails if you become a member. If they do start to send other emails most email accounts have a method of blocking senders.
26) Message boards : Number crunching : Petition For Seti@Home and Arecibo Funding (Message 950818) Posted 29 Nov 2009 by popandbob Post: I would sign a petition, but I don't want to sign up for the service included with the signature, and according to the terms of service, there is no way to opt out. -Dave What service is that? I don't think you have to sign up for anything if you sign.

I was going to start this a couple years ago but never finished it until now. http://www.thepetitionsite.com/1/SETI-at-Home Bob

Eric was going to do an official post about this but never got around to doing it. Bob.
29) Message boards : Technical News : Back and Forth (Oct 28 2009) (Message 945390) Posted 6 Nov 2009 by popandbob Post: The latest version of MS FSX doesn't work virtualized, but I wonder if an older version would work? X-plane has a linux and mac version... I dont think its as good as FSX but its better than older MSFS versions. Bob
30) Message boards : Number crunching : Reached Daily Quota??????? (Message 928737) Posted 26 Aug 2009 by popandbob Post: I've just seen this limit as well... Maybe there is a problem with a config somewhere... I have a quad with a gtx260 and its only letting me have 200/day Bob
31) Questions and Answers : GPU applications : CUDA locking up my computer (Message 923263) Posted 3 Aug 2009 by popandbob Post: I've had this error in the past but upgrading to cuda 2.3 seems to have stopped the problem. Bob
32) Message boards : Number crunching : What's NVIDIA feeding those CUDA 2.3 DLL's? (Message 922942) Posted 1 Aug 2009 by popandbob Post: 7/31/2009 11:43:07 PM SETI@home [error] File cudart.dll has wrong size: expected 192512, got 285696 i replaced the old files with the ones from luna, nd it gives me this.. boinc 6.6.38 and vista 32 bit. That would mean your not using an app_info Using an app_info.xml is required for these dll's Bob
33) Message boards : SETI@home Staff Blog : If fire insurance were like health insurance. (Message 922884) Posted 1 Aug 2009 by popandbob Post: Lets look at defense spending, for this year it was 651.2 Billion dollars. I went to a large airshow last week-end and saw the new F-22 Raptor in action. It is quite the awesome machine (bring ear-plugs) To bad Canada does'nt have any, but then, you will not need any, because Canadians know that if anything really bad happens, we will protect you, we always have. Lets not forget Europe, people from Europe fall into 2 catagories, those whose ass we saved and those whose ass we kicked. Except Great Britain of course (they can take care of themselves. There has been no war that the Americans have protected the Canadians. You have a very sad knowledge of Europe. There are hundreds of countries in europe... How many were defeated with the help of the USA? Three. Germany, Italy, and Austria-Hungary. The US has NEVER defeated anyone without help. Its funny you should mention defence spending... The USA spends lots more on its Military but how much of a deficit do they have? How much is that deficit growing each year thanks to the huge military spending? Bob
34) Questions and Answers : GPU applications : CUDA 2.3 and bigger MB (Message 922208) Posted 29 Jul 2009 by popandbob Post: It is very task specific. I am getting about 10 credits per minute with the majority of tasks taking just over 10 min. Bob
35) Message boards : Number crunching : geforce 260 question (Message 921569) Posted 26 Jul 2009 by popandbob Post: The GTX 260 is now capable with CUDA 2.3 dll's + drivers to get over 10000 RAC Huge speedup with 2.3 (I'd estimate 12k-14k RAC if left on 24/7 and with minimal problems and slowdowns) Bob
36) Questions and Answers : GPU applications : Help with overclocking 9800GX2 (Message 921098) Posted 24 Jul 2009 by popandbob Post: Your overclock is too high and they are having errors. Expect 11-16 min with a high OC. Also Memory overclock doesn't help reduce times. Bob
37) Questions and Answers : GPU applications : CUDA RT2.3 available - upgrade highly recommended (Message 921060) Posted 24 Jul 2009 by popandbob Post: Thats just the CPU time... Check out the difference in elapsed time (wall clock) It is 1.8x-2x faster :) Bob
38) Questions and Answers : GPU applications : CUDA RT2.3 available - upgrade highly recommended (Message 920887) Posted 24 Jul 2009 by popandbob Post: looking at your pending tasks your seeing about double the time I am? unless those weren't done as 2.3's? Bob
39) Questions and Answers : GPU applications : How to install CUDA 2.3? (Message 920885) Posted 24 Jul 2009 by popandbob Post: You need the Drivers (190.38+) from nVidia and the DLL's from lunatics to use Cuda 2.3. The drivers will tell the hardware what it can do and how to do it, the DLL's tell the app this is what to tell the GPU. (or at least that's the analogy I'm using) Bob
40) Message boards : Number crunching : Longer MB tasks are here (Message 920881) Posted 24 Jul 2009 by popandbob Post: zpm if your using 2.3 dll's you have about a 2x speed up so you wont see a difference. Bob Edit: for the GTX260
