21) Questions and Answers : Unix/Linux : \'crashing\' all projects (Message 11720) Posted 9 Apr 2005 by old_user248 Post: Are you still having this problem? From what I understand reading posts in the other forum, the Hadsm3*_4.11 model had some stability problems and that there was a new build, 4.13 available earlier this week. Do you have "Leave applications in memory while preempted?" on profiles page set to "yes"? This can have some effect on the stability of boinc in the M$ environment, I'm not 100% sure the effect in Linux. I take it that you have already tried checking the hardware stability aspects, any overclock still 100% stable, hard drives OK, ran Prime95 torture test, etc? CPDN seems to stress PCs more than most of the other porjects and due to the longer timeframe and interdependancy of caclulations it is very suseptible to caclulation errors. I am wondering about the "CPDN Monitor got quit request..." statement. I don't know much about the CPDN / boinc errors so don't know the whole origin of this, pehaps someone else does and can offer further guidance. Dave
22) Questions and Answers : Windows : Changing Profile on 4.19 (Message 11579) Posted 2 Apr 2005 by old_user248 Post: I am trying to change the profile in use on one of my PCs from home to School so that I can get this machine to run out of work and I can switch it to Linux totally. Changed the profile in use for the PC under my account / Computer summary on the CPDN site and tried to update the preferences from the boinc clinet. I seems forever stuck on the Home profile and will not update. It detects the change but stays there! On Linux this change was very easy. Any ideas? Dave PS cross posted to the CP php community forum
23) Questions and Answers : Windows : unrecoverable error for result (Message 10999) Posted 16 Mar 2005 by old_user248 Post: Your installation of the Climate Model is almost immediately crashing the models. After 2 downloads in one day with error results returned the server halts sending new models to the computer so that the PC doesn't chew through hundreds of models in one day and the operator can try and rectify the problem Can you give us some details on the specs of your PC and are you overclocking. Climate Prediction places a high demand on PCs and if there is any minor problems with the memory, CPU, harddrives, etc., it usually manages to find them and crash. Check out <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=2026">this</a> thread for some ideas on what and how to check your PC. Also, defrag the Harddrive without boinc running, use "Suspend" then "Exit"
24) Questions and Answers : Windows : Climate Crashing WinXP SP2 PC exit code -2 (0xfffffffe) (Message 10998) Posted 16 Mar 2005 by old_user248 Post: > The machines I run CP on are at work, and none of them are overclocked. > > My 2 home machines that are overclocked have no errors whatsoever in any of > the projects, Prime95 passed minimum of 24hrs. Another thing is to check the harddrive. The usual suspects: defrag, surface check, etc. Myself and others have also found that when a HD in a system starts to go it causes the model to crash.
25) Questions and Answers : Unix/Linux : out of disk space, why? (Message 10203) Posted 2 Mar 2005 by old_user248 Post: > Those da files are new to me. I don't have anything like that in the > dataout directory of my linux PC. Very odd. > My dataout directory doesn't contain those files either. Are you running the sulphur cycle or some other experiment? When running 4 concurrent models the maximum that CP took up was just over 3 Gb at the end. That includes new models for processing, etc. Once the 4 new ones started and I backed up the completed models it was back down to around 350 Mb. I think you need to know more from the core CP staff on this to figure out what is going on.
26) Questions and Answers : Windows : Error Code -5 keeps coming - Is CPDN suitable for me? (Message 9605) Posted 20 Feb 2005 by old_user248 Post: > I get this quite frequently, but only after I shut down BOINC, restart BOINC, > and then wait for CPDN to start. It doesn't sem to matter how long I wait for > CPDN to completely shut down. I suspect that there is a problem in the > checkpoint code. Checkpoints are saved at every 144 timesteps. Just to follow on to what mo.v said to ensure that in the boinc front end one suspends, then exit boinc. It does sound as if you are both trying to shut down properly but something is happening to the files being written. If you are having problems running CP one thing to check is the stability of your machine with software such as: <A HREF="http://www.memtest86.com/">Memtest86</A> and <A HREF="http://www.mersenne.org/freesoft.htm">Prime95</A> torture test. These software will test your system to help show if any problems exist. Your problems appear to be with the shut down phase though. Another think to check is that the hard drive is defragmented. To do this you should exit boinc first :) It could be a problem with some of the controling xml files or the restart information written by CP but I am out of my league there. If you have another PC that runs CP OK you could compare some of the files to see if you can find a problem but I don't know if that would help.
27) Message boards : Number crunching : What's your lowest s/TS? (Message 9120) Posted 11 Feb 2005 by old_user248 Post: I don't have numbers for a P4 3.6+, but my FX-53 running an 11.5% overclock gets 1.55 +/- 0.2 sec/TS depending on the particular model run on average. You have to be careful comparing these results as depending on the computational requirments of the particular parameter set the model can run faster or slower. Before anyone makes any changes in their BIOS to the memory timings I highly recomend they read up on the Internet for several days to a week or 2 on overclocking the CPU and memory as well as your particular motherboard. Changes to the BIOS without knowing what the possible effects can be as well as how to recover from mistakes can lock your computer up solid. Also, overclocking your PC increases the heat output and can definitly be detrimental to the stability of your PC. Naylor83: check out MSI's forums at http://forum.msi.com.tw/index.php for good information on your particular motherboard. Here is one post that is quite good at describing many of the possible settings in the BIOS as well as the effects and possible inter-relations. http://www.overclock.net/showthread.php?t=91

I was just quoting the FAQ that was set up in September. There may have been some changes which increases the Hd requirements, and or if as Andrew stated other information downloaded. Mine has been up to 5 Gb but that was including completed models. Once I archive the complete runs it is generally 1.2 Gb. A WinXP Athlon machine with 1 completed model mid phase 2 is using 713Mb. The about 600Mb figure seems right.
29) Questions and Answers : Windows : Graphics / SCR problems (Message 8792) Posted 7 Feb 2005 by old_user248 Post: > Nice to know. Unfortunately, the 1.08 drivers have a bug that limits the > Parhelia 128R 4xAGP to 64MB instead of 128MB, so that's really not an option. > I guess I'll postpone reinstalling BOINC until new Matrox drivers come out. > As mentioned by G Pascal, you could run the project without using the screen saver aspect, or viewing the model if you wish. There is many of us who do not view the model with the built in viewer/screen saver as it can consume a fair amout of your processing power. There is also some other visualisation software available on the site in the FAQ or under "Getting Started" that may work instead. Aother trick some of us found was rolling back to a previous video driver version that worked before the update. Above all thanks for your interest, welcome abord and hope that you manage to find and equitable solution.
30) Questions and Answers : Windows : Disk Space (Message 8789) Posted 7 Feb 2005 by old_user248 Post: Patrick First, welcome to CPDN, we users should be able to help you get things up and running soon. The <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/quick_faq.php#g">FAQ</a> contains some information on how much space each model needs. It needs about 600Mb for each full model run and about 330Mb of information will be left on your computer once a model run is finished and the partial information uploaded. That being said the 1 Gb that you have free will allow you to run about 1 complete model before your Hd becomes full. You should look into clearing up some space on your Hd then defragging the Hd to have as much contiguous space possible. Searching the net with Google should yeild you instructions on clearing up space on your Hd, other than buning CD's of your information.
31) Questions and Answers : Unix/Linux : boinc client version 4.19 (Message 8740) Posted 6 Feb 2005 by old_user248 Post: > When I started a new computer with CPDN recently, it dl'ed 4.19, so I assume > no there is no problem running it.

Some people (myself included) like to wait till either the end of a model run or the end of a phase before doing upgrades but make a backup as mentioned, just in case.
32) Questions and Answers : Unix/Linux : climateprediction slow on linux boxes? (Message 8736) Posted 6 Feb 2005 by old_user248 Post: > Yes, I also get very weird numbers for my Linux computers with respect to ALL > numbers (uptime, up/download rate,.... For my dual Xeon EMT64 3.2 Ghz @ 3.456 GHz running FC3 & 4 models I get FPU of 738.4 and Integer of 1555 which is worse than all my machines, including a 2 GHz laptop running XPPro, so Yup, numbers kinda meaningless. I haven't done a speed comparison, which is very difficult due to processing rates of different models but concensus is that things run faster on Linux.
33) Questions and Answers : Unix/Linux : stderr_um Fortran Error message 63 (Message 8727) Posted 6 Feb 2005 by old_user248 Post: I have begun getting the "forrtl: info: Fortran error message number is 63." error and in the Intel compiler documentation this indicates: Output conversion error: FOR$IOS_OUTCONERR. Durning a formatted output operation, the value of a particular number could not be output in the specified field length without loss of significant digits. When this situation is encountered, the overflowed field is filled with asterisks to indicate the error in the output record. This has not been a critical error to this point. some other text in the error file are as follows: OPEN: File dataout/30ouba.da27bs0 Created on Unit 22 OPEN: File dataout/30ouba.da27c10 Created on Unit 22 CLOSE: WARNING: Unit 60 Not Opened OPEN: File dataout/30ouba.pa28c10 Created on Unit 60 CLOSE: WARNING: Unit 63 Not Opened OPEN: File dataout/30ouba.pd28c10 Created on Unit 63 CLOSE: WARNING: Unit 64 Not Opened OPEN: File dataout/30ouba.pe28c10 Created on Unit 64 CLOSE: WARNING: Unit 65 Not Opened OPEN: File dataout/30ouba.pf28c10 Created on Unit 65 CLOSE: WARNING: Unit 66 Not Opened OPEN: File dataout/30ouba.pg28c10 Created on Unit 66 CLOSE: WARNING: Unit 67 Not Opened OPEN: File dataout/30ouba.ph28c10 Created on Unit 67 OPEN: File dataout/30ouba.da27c40 Created on Unit 22 OPEN: File dataout/30ouba.da27c70 Created on Unit 22 The machine is a Dual Xeon 3.2 Ghz with a mild OC, I'll crank it down a bit to see if this helps but I don't know if this is the problem or not. If anyone knows of this issue please advise, thanks.
34) Message boards : climateprediction.net Science : What would be a 11c warming conscequences? (Message 8690) Posted 5 Feb 2005 by old_user248 Post: We're getting the same in Ottawa with Hazy conditions, just like mid summer SMOG! High predicted of +3Â°C today, melting all over. Wouldn't you figure it through, it's time for our winter carnival "Winterlude" or "Waterlude" due to the temp increases at this time for the past several years.
35) Questions and Answers : Windows : How do I delete a computer from my profile? (Message 7588) Posted 25 Jan 2005 by old_user248 Post: I don't think that you can. If you could delete a computer from your profile you would loose the credit for that PC. Depending, I'm not sure how it works but you may be able to merge it with another PC. I've tried all of this with one PC that I used during the Beta which had very little work done and couldn't do it. Good luck.
36) Questions and Answers : Windows : hadsm3um_4.04 and hadsm3_4.04 (Message 7423) Posted 21 Jan 2005 by old_user248 Post: This is normal behaviour. What you have got is 2 instances of the CPDN Climate Model running and 2 instances of the visulisation software running. There is some instructions for using the visualisation software but they are on the other forum (that I can remember). The visualisation can take a fair bit of processor power when viewing so people have found it best not to leave it running all of the time. Also, the key "0" zero toggles on or off the starfield which reduces the processor load. Hope this helps
37) Questions and Answers : Windows : Windows XP Goes wild. (Message 7276) Posted 13 Jan 2005 by old_user248 Post: > > Hi Geophi > > > > Aprechate your reply the dell came with USB mouse but have swopped it for > > If you haven't already, if there was some special drivers/software that you > installed with the trackball, make sure it is uninstalled. It sounds like > some corrupt drivers, except I don't know why it would only show up when you > are running your CPU at 100%. > I am no expert but it definitly sounds like some sort of driver conflict between your mouse and something. Do things go crazy when you try to view the visualization? Now that I think of it CP uses openGL (I think) for the visualizations, maybe try updating the drivers for the Mouse and video card, or if MS just kindly updated things for you maybe try going back to the last version of the drivers. With a little searching around on this or the other forum you should be able to find out what is used for the visualizations and ensure that the latest version is installed. Good Luck DaveN EDIT: Just notcied the post a couple down "Got problems, may have the answer here". Maybe the drivers that are pointed to could help.
38) Questions and Answers : Windows : Safe to delete old work-unit on hard drive?

Also, you can look at the same time to see if the particular model has been sent out again and if someone else had any luck completing it. Hope this helps a bit. DaveN
39) Questions and Answers : Windows : ZoneAlarm update prevents BOINC from starting work (Message 6999) Posted 17 Dec 2004 by old_user248 Post: > >The problem may have gone away, or <b>only occurs at re-boot.</b> > > I think this is it.

I thought my machine had become unstable and tried running Prime95 and it would open but the processor activity would stay at minimal. Usually takes me 3-5 reboots and long waits to get it going. I was thinking of uninstalling the latest update to see if things started behaving.

There may be other threads that can help, sorry that I couldn't.
