61) Message boards : Number crunching : Many .01 Results (Message 30797) Posted 8 Nov 2006 by BennyRop Post: 0.01 rmsd results only show up on 2 of the WUs I've turned in; one of which was my 0.01; although someone else had a better (lower) energy than my result. It does seem like the rmsd calculations are broken.
62) Message boards : Number crunching : Low Scores Anyone? (Message 30405) Posted 1 Nov 2006 by BennyRop Post: Give 5.36 a try, and if you get equally bad results, then Rhiju's changes to 5.36 didn't cure the issue for your machine. Post a message in the 5.36 error thread. We don't always get personalized replies here. I may have got a few - but most of them were (Your message has been moved to another thread because it was off topic.) grin
63) Message boards : Number crunching : CPU Time not accurate? (Message 30324) Posted 30 Oct 2006 by BennyRop Post: http://boinc.bakerlab.org/rosetta/results.php?userid=38837 I'm still reporting about 86,400 seconds of crunching around every 86,400 seconds. (Losing about 5 mins a day?) Where are you seeing that Rosetta is only getting 1min 30 seconds of cpu time every 30 mins? Is that from Boinc, from windows task manager, or some other program? And if you pull up the windows task manager.. what process or processes is/are getting the most cpu time?
64) Message boards : Number crunching : High Scores Anyone? (Message 30252) Posted 29 Oct 2006 by BennyRop Post: http://boinc.bakerlab.org/rosetta/result.php?resultid=44436068 http://boinc.bakerlab.org/rosetta/result.php?resultid=44392864 328 and 545 points for 18? seconds seems a bit out of line. :)
65) Message boards : Number crunching : Report problems with Rosetta version 5.34 (Message 30193) Posted 28 Oct 2006 by BennyRop Post: If hardware tests come back saying the hardware is fine; connecting systems with high error rates to Ralph (at least giving them some time on Ralph) will help track down the source of the higher than average errors showing up on some systems.
66) Message boards : Number crunching : Low Scores Anyone? (Message 30145) Posted 27 Oct 2006 by BennyRop Post: Someone last night mentioned having a few WUs turned in that were given much lower credits and blamed it on 5.34. They were getting around what they asked for by 5.34 until they started running WUs that were similar to this: 1hz6A_BOINC_NATIVEJUMPS_CLOSE_CHAINBREAKS_VARY_ALL_BOND_ANGLES_SAVE_ALL_OUT__1306_8456_0 and then they were suddenly getting 1/3rd of the their claimed credit. You're doing much better in that regard; getting 44 and 48 when asking for about 60. (Although one didn't get to the 25k second range.). With the large range of problems with your winxp machine, would you mind trying to diagnose the problems? Rule out hardware problems on your end by testing the ram with Memtest86+, some type of HD check - (windows checkdisk is a start - but the diagnostics from your HD's manufacturer would be better second test.) And if those don't help identify the problem, perhaps turning off the Rosetta screensaver and seeing if it is contributing to the problems on your system. (By eating up more ram than usual, it may be causing the main Rosetta application to use defective ram that hasn't been used on other projects or WUs that didn't have an error.)
67) Message boards : Number crunching : Edwins' issues (Message 30141) Posted 27 Oct 2006 by BennyRop Post: If the hardware (ram and hard drive tests) passes, there was mention of the screen saver having problems with some systems. (It'd help to identify your video card and video driver version if that ends up being the problem.)
68) Message boards : Number crunching : OT: A closer look at Folding@home on the GPU (Message 30088) Posted 27 Oct 2006 by BennyRop Post: One model of the new G80s was listed as having 96 shaders, and the top end was listed as having 128 shaders in the german review I read.
69) Message boards : Number crunching : OT: A closer look at Folding@home on the GPU (Message 30068) Posted 26 Oct 2006 by BennyRop Post: If you've been following the F@H GPU saga for the past few years, you'll remember that it started with nVidia cards - which were considered the most powerful at the time. They finally abandoned nVidia development and went ATI due to cards like the x1800 being setup with enough shader engines with 32 bit precision to make the job relatively easy. Mr. Houston also mentioned that nVidia is using a technique to hide latency that also caused problems for the GPU code. When nVidia switches approaches - then we'll likely see the latest nVidia cards being supported. If Intel can switch from Speed-at-all-costs to multiple cores at reasonable speeds with higher instructions per clock - following AMD's lead, then there's hope for nVidia's following ATI's lead. And yes, I, too, am an nVidiot, not a fanATIc. :)
70) Message boards : Number crunching : 0 credit work unit? (Message 30026) Posted 26 Oct 2006 by BennyRop Post: For the validate section of each of those.. #1 says "invalid" #2 says "valid" #3 (Matt's) says "workunit error - check skipped." is that the normal message for a WU turned in after a valid WU?
71) Message boards : Number crunching : Report problems with Rosetta version 5.32 (Message 29981) Posted 25 Oct 2006 by BennyRop Post: One of the systems having continuous errors lately ended up being a problem with bad ram. Perhaps others having a high failure rate could test out their system with memtest86+ from http://www.memtest.org/. I remember some of the errors that popped up with Distributed Folding actually telling us to test our systems with memtest86 to verify that our memory was okay.
72) Message boards : Number crunching : Report problems with Rosetta version 5.32 (Message 29914) Posted 24 Oct 2006 by BennyRop Post: http://boinc.bakerlab.org/rosetta/result.php?resultid=43235925 http://boinc.bakerlab.org/rosetta/result.php?resultid=43309102 http://boinc.bakerlab.org/rosetta/result.php?resultid=43333974 http://boinc.bakerlab.org/rosetta/result.php?resultid=43586861 Are these errors pointing to Rosetta client issues, WU issues, or possible client software/hardware issues?
73) Message boards : Number crunching : why is this machine failing so much? (Message 29913) Posted 24 Oct 2006 by BennyRop Post: Have also started to get more failing wu's. Is there a running log kept of failures to identify a pattern in the making? Your system seems to be getting more and more failing WUs for each page of 20 results. Running the same hardware tests that were recommended to Zombie67 would help rule out your system as the source of the problem. We can also post the errors in the "Report problems with 5.32" thread.
74) Message boards : Rosetta@home Science : Profiling cancer tumors for best treatments (Message 29912) Posted 24 Oct 2006 by BennyRop Post: Full article here. WASHINGTON (Reuters) -- A new test that looks at genetic material from a patient's tumor is 80 percent accurate in predicting which drugs would be most effective against that particular cancer, U.S. researchers reported Sunday. The test can be used to predict not only whether a single drug can work to stop a tumor but whether a specific combination of drugs will work, the team at Duke University in North Carolina reported. Writing in the journal Nature Medicine, the researchers said they used a "gene chip" made by Affymetrix as the basis of the test, done in lab dishes using tumor samples from several hundred different patients with leukemia and ovarian, breast and lung cancers. Interesting way to choose the most effective treatments for your tumors. How much study for other illnesses before a similar approach will work for them?
75) Message boards : Number crunching : OT: A closer look at Folding@home on the GPU (Message 29905) Posted 23 Oct 2006 by BennyRop Post: The G80 had 96 shaders for some models, and 128 shaders for the high end part in the german review I read. Hopefully, they've ironed out the other issues that caused the nVidia chips to perform so poorly over at FaH. With the competition to provide better crunching between ATI and nVidia, it'll hopefully make any portion of the Rosetta app that is ported to a GPU client just scream along.. if the Rosetta Team gets a GPU coding guru on staff.
76) Message boards : Number crunching : why is this machine failing so much? (Message 29904) Posted 23 Oct 2006 by BennyRop Post: Remove the Ram and retest one stick at a time. Stop on the first failure. That module is bad on that particular motherboard. Test any remaining sticks. Seti, etc must have a smaller memory footprint, and not touch the affected memory area that is bad. We ran into problems like this when people started working with memory hog software after using their system problem free for a year.
77) Message boards : Number crunching : why is this machine failing so much? (Message 29893) Posted 23 Oct 2006 by BennyRop Post: Once should be enough to catch the memory errors; but I leave it running overnight to verify that there aren't any intermittent errors. With the number of errors your WUs are having in less than 3 hours, 1 pass should be enough.
78) Message boards : Number crunching : why is this machine failing so much? (Message 29862) Posted 23 Oct 2006 by BennyRop Post: Where does one get Memcheck86+? [...]This is a linux box, will it run on linux? Argh. It would help if I used the right name for the program. (Memtest86+). I've always used the iso from the linked web page for bootable cds, or floppies. So it doesn't care what OS you have installed on your HD. It's also included on The Ultimate Boot CD 3.4 (although there's probably a newer version out by now.)
79) Message boards : Number crunching : why is this machine failing so much? (Message 29818) Posted 22 Oct 2006 by BennyRop Post: Have you tested the hardware with Memcheck86+ and a HD diagnostic from the manufacturer of the HD.. (the whole collection of current manufacturer's HD diagnostics are on the Ultimate boot CD). And temporarily setting up a clean install of the OS on another HD, install Boinc and let it load a fresh copy of Rosetta - to see if the problem disappears with a clean install?
80) Message boards : Number crunching : Dedicated 3.2GHz HT P4 with 25.25 RAC? (Message 29715) Posted 20 Oct 2006 by BennyRop Post: Since it's getting about 1/10th of what it used to - I'd check for the system going into hibernation mode after 2 hours. Right click on the desktop, choose "properties", choose screen saver, choose advanced, and make sure the hard drive shutdown and system hibernation is set to "never".
