21) Message boards : Number crunching : PS3 preliminary crunching numbers (Message 41798) Posted 3 Jun 2007 by Jack Shaftoe Post: Thanks for the post. I think we will see some scientific crunching on the Xbox 360, it will be interesting to see which project. Sorry to rain on your parade, but... I'm willing to bet you won't see many 360 owners crunching for science because the console is plagued with so many hardware failure problems compared to PS3. Much of it is related to heat. There are lots of angry 360 owners and lots of dead consoles going to Microsoft in a "coffin" to get replaced by a refurb. I've been very frustrated with Microsofts lack of attention to this issue, as I was hoping to get a 360 this year and get Halo 3. (sigh) If I somehow find $600 in my sock drawer and get a 360 and 1 or 2 games - I have to admit I won't crunch for science. It's too risky on that console... I'll stick with my computers, which are better designed for reliability.
22) Message boards : Number crunching : AMD's 65nm CPU's - Any Thoughts? (Message 41649) Posted 30 May 2007 by Jack Shaftoe Post: Dont know how good the 4000+ will crunch tho, a friend of mine had a 4400+ (socket 939) running rosetta, and it was returning 2 times ~30 credits in 3 hours, so far from beeing a crunching monster. I have one of these, and was really frustrated when AMD went to socket AM2 shortly after I bought it. Not really any upgrade paths without replacing the board now. grr... Still, it's a good chip for the money. Runs a little hot though.
23) Message boards : Number crunching : AMD's 65nm CPU's - Any Thoughts? (Message 41648) Posted 30 May 2007 by Jack Shaftoe Post: I'm guessing the original poster doesn't want to have to upgrade the motherboard, so it's not just the cost of the processor that they are concerned with... Yes - I will get a new MB. There is no way for me to upgrade without doing so. Looks like there is a lot coming up, so I will probably re-evaluate at the end of the summer. Regarding the quad cores. My E6600 is giving me ~900 credits per day. The quad core at the same frequency (2.4 GHz) gives another team member ~1400 per day. I found that kinda disappointing, but it will still be good for under $300 later this summer. I was hoping it would at least push out 1500 - 1600. Thanks for the replies.
24) Message boards : Number crunching : AMD's 65nm CPU's - Any Thoughts? (Message 41550) Posted 28 May 2007 by Jack Shaftoe Post: I realize that C2D is generally the consensus for performance per $$, but some of the AMD CPU's are very cheap and I am on a tight budget for upgrading one of my crunchers this summer from a Sempron 2500+. Does anyone have any experience or thoughts regarding the 65nm X2's (Brisbane)? The 4000+ is only $100 right now... Are they significantly cooler than the 90nm choices? Thanks for any opinions,
25) Message boards : Number crunching : turn off hyperthreading? (Message 37960) Posted 18 Mar 2007 by Jack Shaftoe Post: I can't believe that people still think that they can produce more with HT turned off. Sad. Hmm... If it's such a good thing, why wasn't it included with the C2D's??? Confused.
26) Message boards : Number crunching : Sony plugs PS3 into folding@home (Message 37959) Posted 18 Mar 2007 by Jack Shaftoe Post: Wow, this is very cool. Congrats to F@H! Good press for DC projects in general. I wish I had an option to do this with Rosie...
27) Message boards : Number crunching : 80 cores, not science fiction ... it is real! 1.2 TERA! (Message 37639) Posted 9 Mar 2007 by Jack Shaftoe Post: Can t wait to see the productization of all those great discoveries. I imagine it will be a long time before average Joe's can consider owning something like this. We need to buy our way through the current chips so Intel can make as much money as possible off all of this.
28) Message boards : Number crunching : Best CPU for a silent cruncher? (Message 35623) Posted 27 Jan 2007 by Jack Shaftoe Post: If someone already has a pointer to a review/report site that includes power-under-load as part of the analysis (for CPUs, or better yet mini-ITX, micro-ATX, and other similar small-form-factor systems), I'd appreciate any help. Thanks! I don't have a link, but I can offer some experience from a similar project I completed. -- I recently built a living room mediacenter desktop that sits in my stereo shelf system and gets used as a jukebox and gets plugged into the projector to play movies. It's not too low-profile, as the case is a bit taller than the rest of the components, but it fits right in. http://www.newegg.com/Product/Product.asp?Item=N82E16811112082 I went with a Core 2 E6600 @ 2.4Ghz and I used the stock heatsink. I even gave it a modest bump to 2.66Ghz, and the whole system (which runs BOINC 24/7) is still quieter than the cable box with DVR that we got from Comcast. It's not even noticeable in my opinion. I was very happy with the result. The E6600 gives me a really nice amount of credits too. :) HTH P.S. I should mention that the plastic internal 3.5" drive bays they used are the only downside of the above case. Other than that, it's great.
29) Message boards : Number crunching : Strange Computers (Message 34540) Posted 11 Jan 2007 by Jack Shaftoe Post: I'm sure if you looked at our department account (housing and food services), and probably this account, there are thousands of 'computers'. In our public labs we use a bit of software called deep freeze. Upon reboot, it deletes all changes a user has made to the system since the last restart. I didn't do a great job building the image deployed to the lab computers, so each time the machines restarted it had to reattach to Boic creating a new host ID. I wish all schools attached their computer labs to Rosie. :)
30) Message boards : Number crunching : BOINC backing off too long (Message 32991) Posted 20 Dec 2006 by Jack Shaftoe Post: So what BOINC version is doing that? The version is 5.4.9. You might try 5.4.11 Gerry and see if the problem persists.
31) Message boards : Number crunching : Over night, The Dual Xeon 5335 will pass RAC=3000 :) (Message 32890) Posted 19 Dec 2006 by Jack Shaftoe Post: why don't you come here, the Rosetta cause is very noble, and we need more people processing here. Hear hear! :-) What do you say XS VS?
32) Message boards : Number crunching : Putting Servers back to work (Message 31807) Posted 29 Nov 2006 by Jack Shaftoe Post: I had pulled some servers into another project. The project was causing me a lot of issues, so I moved them back to here. It should be a decent bump in RAC over the next day or so. Damn! There goes my chance to sneak away from you. It's gonna be a race! Look out dag! Lean into the curve!
33) Message boards : Number crunching : Report problems with Rosetta version 5.36 (Message 30950) Posted 11 Nov 2006 by Jack Shaftoe Post: > ...another "disk space exceeded" error Same here, 3 straight WU's, plenty of disk space. Darnit! For what it's worth, they are all FRA_t369 tasks. Something is wrong with those WU's. I've lost every single one of them with this error - about 15 so far. I'm aborting the remaining 8 in queue.

35) Message boards : Number crunching : credit/hour how much is possible?? (Message 30611) Posted 4 Nov 2006 by Jack Shaftoe Post: E6600 @ 2.63ghz = 22.18 c/h/core 4400+ Toledo @ 2.42ghz = 14.25 c/h/core Xeon 5160 @ 3.0ghz = 20.14 c/h/core Relatively small sample of 8 workunits at 8 hours each.
36) Message boards : Number crunching : HUGE WU's (Message 28771) Posted 30 Sep 2006 by Jack Shaftoe Post: 3 MEG ??????? This is worse that SIMAP ! Not so, I joined SIMAP for a month until I noticed I was sending/recieving over 3GB of data per day! (Holy smokes!) Now that I'm back here it's down to a more manageable 300 - 400 MB's. If you want to reduce the bandwidth I think setting up one of your machines as a proxy would help you as the files would only need to be downloaded once each no matter how many clients were using them. A good idea, although I'm not sure that will work for the WU's. As was said earlier - another trick is to increase your WU time so it runs them longer. If you use 12 hour WU's you should see a lot fewer 3MB WU's than the standard 3 hour setting. Welcome back Kevin!
37) Message boards : Number crunching : More checkpoints please. (Message 27182) Posted 17 Sep 2006 by Jack Shaftoe Post: On a Windows system I run, I just opened BOINC Manager to see what was happening with the current tasks. I have 6 hour WU's, and the current WU was just over 4 hours done - plenty of pending work, seems to be working well. Then I make a mistake, and instead of closing BOINC Manager by hitting the X in the top right, I accidently go File > Exit. Oops! I've done this with BOINC a few times over the past couple months, so I know I'm going to lose some work for it (because it kills the app). Unfortunately I dropped back 3 hours to just over 1 hour completed. Please include more checkpoints in the next release - every 1 hour would be great. Leaving the app in memory is not an option for a fair of my machines since I don't want Rosetta eating up resources while other users need the hardware. I hate seeing that much work wasted! Thanks for reading. ST. (back on Rosetta now that it has cooled off around here)
38) Message boards : Number crunching : Bye bye Rosetta (Message 25447) Posted 29 Aug 2006 by Jack Shaftoe Post: Hi Administrator and John, please refrain from personal attacks against each other. What would help is not allowing normal folks to use forum handles like "Administrator". It's confusing and disruptive - this is what John was saying prior to the verbal garbage that got directed at him and forced him to retire. I fully agree. Ignore this board. Perhaps this is better advice. Count me in, good luck Rosetta. I'll still crunch for you (with a lower resource share), but I've had enough with the icor on the boards. For what it's worth, I don't blame the project or the forum mods for what has happened here over the last 2 weeks. I agree it would have been better if they had spent more time working with the community to prepare us and include us, but they are not responsible for what everyone else posts here.

40) Message boards : Number crunching : Report Problems with Rosetta Version 5.25 (Message 24264) Posted 22 Aug 2006 by Jack Shaftoe Post: he has moved all of his machines to WCG Yesterday. Sorry we couldn't have helped sooner. It's good to know another project that uses Rosetta will benefit from the extra work. Ethan - could you please elaborate on this? Does WCG crunch Rosetta too? If so, cool!
