1) Message boards : climateprediction.net Science : Graphics Problems with Boinc (Message 14339) Posted 13 Jul 2005 by LochDhu Post: > I am disturbed by posts suggesting that the upload may not work > automatically and you may have to search through your harddrive to find the > missing files. Ed & Harriet Griffith, This was an issue in the pre-BOINC version. To my knowledge it hasn't happned to anyone with BOINC. However, some people still use the pre-BOINC version, because of BOINC's other anoyances.
2) Message boards : Number crunching : hadsm3 4.04 keeps running (Message 10697) Posted 11 Mar 2005 by LochDhu Post: Just to clarify for anyone else who might read this, crandles is referring to hadsm3 4.10 not BOINC 4.10.
3) Message boards : climateprediction.net Science : Just got back here... have a couple of Qs... (Message 10606) Posted 9 Mar 2005 by LochDhu Post: She might also be interested in how to prevent Classic from downloading another model. It was long ago when I first BOINCed, but I think it was a setting you had to change in your CPDN profile.
4) Message boards : Cafe CPDN : CPDN WOWmugs are available to buy! (Message 10389) Posted 4 Mar 2005 by LochDhu Post: How about a bunch of us CPDNers in the States do a group buy to save postage? Order a group of 30 or so, and then distribute to each individual at a more reasonable rate of $6.50.
5) Message boards : Number crunching : What\'s new in hadsm 4.10? (Message 10388) Posted 4 Mar 2005 by LochDhu Post: I like the new W view. It's nice too see the whole surface area of the earth at once. It will be espically useful for posting screenshots on the boards.
6) Message boards : Number crunching : .7 sec/TS difference in computation of phase 1 or 2 (Message 10387) Posted 4 Mar 2005 by LochDhu Post: Perhaps is started to be a fast iceball, but the model caught it and did a roll back.
7) Message boards : Number crunching : What\'s new in hadsm 4.10? (Message 10314) Posted 3 Mar 2005 by LochDhu Post: I started BOINC&CPDN on another PC and it downloads a hadsm 4.10 model. Is this the new Sulfur cycle? [excited] This is an older PC; something like a P2, but I don't know the Mhtz. It's running like 10s/Ts! Is this PC simply that slow or are there startup calculations and it will speed up later or is it the additional sulfur calculations? Info on this is probably around, but searching on the BOINC boards is sooo bad.
8) Message boards : Number crunching : seti project renamed as climate prediction (Message 10217) Posted 2 Mar 2005 by LochDhu Post: I think I remember this problem with early versions of BOINC like 4.05 and ealier. What version are you running?
9) Message boards : Number crunching : Bad for CPU to run 100%, 24/7 @ 62 degrees? (Message 10098) Posted 28 Feb 2005 by LochDhu Post: Some cases do have temp readings on the front.
10) Message boards : Number crunching : Status of upload? (Message 9845) Posted 23 Feb 2005 by LochDhu Post: My files are uploading OK now. (aside from an occasional failure due to volume issues.)
11) Message boards : Number crunching : Is CPDN/BOINC faster with SSE3 on Opteron? (Message 9774) Posted 22 Feb 2005 by LochDhu Post: This article from Tom's Hardware Guide is about the new Pentiums, but it mentions in passing that the new Opterons have SSE3. <a href="http://www.tomshardware.com/cpu/20050221/prescott-01.html">Prescott Reworked: The P4 600 Series and Extreme Edition 3.73 GHz</a> With our current compile, with the Intel compiler, would it use SSE3 on an Opteron? I think Intel chips would still have the advantage with hyper threading. But if your really anti-Intel and the heat they produce, could you get a Opteron or multi-Opteron system and get similar results? Not that I could afford such a thing anyway, but hypothetically. . .
12) Message boards : Cafe CPDN : Sulphur cycle alpha test new version 4.09 released (Message 9766) Posted 22 Feb 2005 by LochDhu Post: How much longer does it take to complete a 4.09 model compared to 4.04 on your PC?
13) Message boards : Number crunching : Status of upload? (Message 9765) Posted 22 Feb 2005 by LochDhu Post: Yes there is an upload issue, but download of new models is unaffected. Fortunately, BOINC handles this well and continues processing new a models, and when the server issue is fixed your completed model will be uploaded automatically.
14) Message boards : climateprediction.net Science : Leap of Faith (Message 9280) Posted 14 Feb 2005 by LochDhu Post: Some localized oddities are normal in Phase one, but if your model is turning into Titan in Phase one, you may have some hardware instabilities.
15) Message boards : climateprediction.net Science : Leap of Faith (Message 9147) Posted 11 Feb 2005 by LochDhu Post: The first 15 years are called the spin-up phase because it is calabrating itself before the real experiment begins in phases 2 and 3. Strange weather is normal during the first phase.
16) Message boards : Number crunching : How much time in the processing of 1 model ? (Message 9086) Posted 10 Feb 2005 by LochDhu Post: That's about right. Predicting climate isn't easy.
17) Message boards : Number crunching : Why doesn\'t BOINC work? (Message 8830) Posted 7 Feb 2005 by LochDhu Post: If you don't know if you are overclocking, then you aren't. It involves some special steps in your BIOS and can't be done accidentally. That rebooting is very mysterious. Does it behave similarly with other BOINC projects or other non-BOINC distributed computing?
18) Message boards : Number crunching : Do I have more errors than the average person? (Message 8826) Posted 7 Feb 2005 by LochDhu Post: Are you running the BOINC 4.05 version or were some of the failures on that version? That version had an error in an XML file that causes a failure on model upload. Any work units downloaded with version 4.09 or later will not have this problem.
19) Message boards : Number crunching : Why doesn\'t BOINC work? (Message 8632) Posted 4 Feb 2005 by LochDhu Post: On the computer that reboots, run MemTest: http://hcidesign.com/memtest/ If it can't make two complete passes without errors, then that computer isn't fit to run CPDN or any distributed computing project. One of my PCs started crashing, while running CPDN after 5 months of smooth operation. I think and hope I have traced the problem to a power supply that isn't giving the correct voltage. As for the screen saver, does it not show at all? Just a blank screen? Does it give that "Secure Windows Desktop detected" message? What operating system version?
20) Message boards : Number crunching : Model 346646 uploaded, but not Complete (Message 8541) Posted 3 Feb 2005 by LochDhu Post: > It looks like the last trickle of phase 3 was not recorded as uploaded.

What happens if > you restart BOINC on that PC? > This is my slowest PC at ~6.6 sec/T. I decided it should switch to smaller work units. I set the "leave at least this much free space" setting to 99GB to prevent another model download. After BOINC uploaded all the files it wanted, I upgraded to 4.19 and attached to Predictor and LHC. It is happily running Predictor and will run LHC when it is back. Could the leave free space option have prevented a critial file from uploading? mickus says something about a "follow up trickle." What is this?
