21) Message boards : Questions and problems : Two machines accomplishing nothing (Message 47199) Posted 12 Jan 2013 by mitrichr Post: Mind telling what exactly you added in the cc_config.xml file? Mind telling which projects you're talking about? Or which applications? Have you taken into account that since you cleaned up everything BOINC, that BOINC 7 is really starting off clean and that it now takes time for it to learn all about the applications again? Are you running 24/7, or other? With which cache, as in what are your settings for Maintain enough tasks to keep busy for at least X days and for ... and up to an additional X days? Where did you set these preferences? Ach, as usual, a good friend looking to rescue the hapless soul. Here is the cc_config file, added into B OINC Data just to eliminate GPU's: <cc_config> <log_flags> <sched_op_debug>1</sched_op_debug> <debt_debug>0</debt_debug> <work_fetch_debug>0</work_fetch_debug> </log_flags> <options> <client_version_check_url>http://www.worldcommunitygrid.org/download.php?xml=1</client_version_check_url> <client_download_url>http://www.worldcommunitygrid.org/download.php</client_download_url> <network_test_url>http://www.ibm.com/</network_test_url> <start_delay>120</start_delay> <no_gpus>1</no_gpus> </options> </cc_config> Projects Asteroids, CAS, Einstein, eOn2, LHC@home, Milky Way, SAT@home, Cosmology@home, WCG. Running 24/7 Caches: "Minimum work buffer" (used to read "Connect every...") I leave at the default. the i7-840 installed this as "0.00 days", the i7-920 installed this as "0.10 days". The "Max additional .." on both is 1.25. The preferences are set in BOINC Manager\Tools\BOINC- Preferences on each computer.
22) Message boards : Questions and problems : Two machines accomplishing nothing (Message 47197) Posted 12 Jan 2013 by mitrichr Post: I have six machines of varying ages crunching on a variety of projects. Two machines have recently begun to accomlish absolutely nothing. Both are modern machines, one an i7-840 laptop with 8 gigs of DRAM and crunching on 5 threads with 7.0.28 on a variety of projects. The other is an i7-920 desktop with 6 gigs of DRAM and crunching 7.0.28 on 5 threads. Both machines have been cleaned and vacuumed, both are running with tthrottle because of excessive heat. Both are running the 5 threads at 100%. Two machines, an i7-3930k with 16 gigs of DRAM is just fine on 7.0.28, and an i5-520M with 4 gigs of DRAM is fine on 6.12.34, both doing plenty of work. Both are also using tthrottle. When I started to see problems about two weeks ago, I un-installed 6.12.34, deleted BOINC and BOINC Data, edited the Registry to eliminate BOINC and WCG, re-installed with 7.0.28, copied in appropriate cc_config files mostly to ignore GPU's. I re-attached to the various projects, and the problems have continued. On both machines, the Remaining time is moving up not down. I do not kow what to try next. Any help will be appreciated.

24) Message boards : Questions and problems : Suprised to find an overabundance of "High Priority" tasks (Message 47083) Posted 6 Jan 2013 by mitrichr Post: What are your cache settings? (both of them) Claggy O.K., too many terms for my pea sized brain. I leave "Connect every" at the default on installation. Additional work buffer is mostly 1.25, in case of ISP problems. I have been using these settings for a long time with no difficulties. You know, I have been crunching for a long time without these difficulties. I do not think anything here has changed. I think that I got "High Priority" WU's inherited from people who turned off their equipment over the holidays. That is what it looks like in my flat-lined stats in BOINC Manager. It's just too much to be coincidence. I am now not going to touch anything, and I will see if it straightens out as this stuff moves through the systems.

26) Message boards : Questions and problems : Suprised to find an overabundance of "High Priority" tasks (Message 47076) Posted 6 Jan 2013 by mitrichr Post: It sounds to me like the 3 hosts you mention are downclocking and that is why they are taking so long to complete tasks and that is why they're in high priority and about to miss deadline. The most likely cause for downclocking is overheating and the two most common causes of overheating are dust and failed or failing cooling fans. What to do? Fire up the diagnostic softwares and check temperatures and fan speeds while BOINC is running. Listen to the fans to see if you can detect a howling bearing. That's one fan failure mode... the bearings wear out then the shaft doesn't spin freely and the fan won't rev up to high enough speed to do its job. It makes a squealing/howling noise. Make a simple stethoscope from a piece of hose and listen to each fan. If you hold a bad fan just right, rotate the blades slowly with your fingers and concentrate you can sometimes feel the roughness in the bearing if it's in very bad shape. The other failure mode is that the magnets in the motor become weak due to spinning through Earth's magnetic field and other causes so the motor loses power. There are no audible clues to that mode you can only use the fan tachometer in the diagnostic software. If you're not cleaning the dust out at least twice a year you're asking for trouble. I replace fans once per year whether they need it or not. I reduce the number of fans I use to a minimum through shrewd thinking and I buy top quality fans at lo cost because I know where to buy them. I install 'em myself because it's easy and because I've learned how to not injure myself with a screwdriver. It works out to be very inexpensive and my hosts never go down just over something as silly as overheating or being at the geek shop for two days accumulating a $200 bill for $7.97 worth of parts and 10 minutes labor. Preventive maintenance: fixing stuff before it breaks and before you lose production. Maintenance: fixing stuff after it breaks and after you lose production. Thanks very much. While heat has been a problem in the past, especially on the laptops, I have taken the necessary steps to minimize that, vacuuming the fan(s), I run tthrolle, I also use exterior fans to exhaust heat. My temps on the two laptops are in the 50's C, the desktop 40's C. But, the really telling thing for me, when I "Show Active Tasks", I have many tasks from my projects in the 1-5 hour range, and then, waiting to start, I see one of over 100 hours. So, I do not believe that it is my machines, I believe rather, it is something in the assignment of the tasks. I know BOINC recognizes the CPU, and both laptop CPU's designations end in the letter "M", so BOINC knows they are laptops. Thanks for the suggestions.
27) Message boards : Questions and problems : Suprised to find an overabundance of "High Priority" tasks (Message 47069) Posted 6 Jan 2013 by mitrichr Post: I just checked my stats on several machines. I was surprised to find most projects flat-lined since mid to late December. So, I looked at the tasks. I found an over-abundance of "High Priority" tasks. Some go for over 100 hours. This is on a number of different projects. Now, this is on several of my least capable machines, two laptops , one a hyper threaded dual core running three threads, one a hyper threaded quad running six threads. The third machine is a hyper threaded quad desktop running six threads My supposition is that I inherited these tasks from people who shut down for the holiday period, which I did not do. I cannot see any way that all of these tasks can be successfully finished by their deadlines. Is there not something in the BOINC process which assigns work to machines capable of doing that work? If my machines fail at some of these tasks, then will that not affect the "reliability" measures on those machines for those projects?

29) Message boards : News : New project studies asteroid properties (Message 46993) Posted 1 Jan 2013 by mitrichr Post: Somehow, I got it done. I found a page which took my email address, I said I forgot my password, I got an email where I could change or post my password, it all worked, I am attached on two machines. Now, I just need my CPID to straighten out, which I assume will happen in a few days. Sorry for the confusion. But the project had me having registered for the project when I had not ever registered for the project, just globally registered my team.
30) Message boards : News : New project studies asteroid properties (Message 46989) Posted 1 Jan 2013 by mitrichr Post: I found the problem. On June 19, 2012, I found that I could set up my team globally all at once for all projects, so that I did not need to do it every time I attached to a new project. I searched for any sort of clue on this project in Statistics/Top Participants, and found "mitrichr". So, there, I used the user name mitrichr. The user id on this project is 1563. I never attached to the project, but that must be how my email address got into the system. I did not know many of the projects where my team was established. I thought it would make things easier in the future. I have since attached to a number of projects without any of these difficulties. So, now, how do I attach to this project, when the project is telling me that the email address has already been used? Any help will be appreciated.
31) Message boards : News : New project studies asteroid properties (Message 46988) Posted 1 Jan 2013 by mitrichr Post: How can you not know what's going on? It told you what's going on... someone already registered an account with that email address. The reason it told you the password you used is wrong is dead simple... the password you typed is not the password associated with that email. How can this all be? There are a number of logical explanations: This is all pure rubbish. I have never even heard about this project before I saw Dave's post. I am not in any way attached to this project on any of my machines.The email address I used is correct, the password I used is correct, as I said, I used them to attach an existing project to a new computer just to confirm, although that was hardly necessary. So, much as I would like to add my machines, I guess the project will have to count me out. Pity's the sake, I get a lot of work done.
32) Message boards : News : New project studies asteroid properties (Message 46983) Posted 1 Jan 2013 by mitrichr Post: I had the idea of adding to a project on which I already work to another computer which was not currently attached to that Project. I had a computer on which I was not attached to Rosetta. I added that project with my email address and password just fine. This just adds to my puzzlement.
33) Message boards : News : New project studies asteroid properties (Message 46982) Posted 1 Jan 2013 by mitrichr Post: This project refused to allow me to attach. I put in my email address and password, the same ones on all of my projects, the response was that there ws already an account set up and that my password was incorrect. I tried this several times on two separate computers. I don't know what's going on.
34) Message boards : GPUs : Milky Way fails on my GPU (Message 46903) Posted 23 Dec 2012 by mitrichr Post: Jord- I did some more searching about Milky Way and GTX670's, and saw comments that the nVidia cards lacked good "double precision", required by Milky Way but not SETI, EINSTEIN or GPUGrid.
35) Message boards : GPUs : Milky Way fails on my GPU (Message 46861) Posted 18 Dec 2012 by mitrichr Post: Thanks, I sent the link on a forum post.
36) Message boards : GPUs : Milky Way fails on my GPU (Message 46859) Posted 18 Dec 2012 by mitrichr Post: Hey Jord- Thanks. How are you? It's very strange. SETI ans EINSTEIN GPU work units do quite well. I wanted also to run Milky Way on GPU, my blog has taken a definite tilt toward Astronomy. I was originally running GPUGrid, very successfully, but I found that I needed to drop that project. GPU processing is very strange. I think that the projects do not play well with each other. The resources should not be a problem. The i7-3930k is a hyper threaded six core, I am only crunching CPU work units on nine cores (threads). The machine has 16 gigs of memory and the machine does nothing but crunch. So, memory should not be an issue. At another project, I had been warned away from Milky Way on GPU on GTX 670's; the project said they should be fine. For now, I am just going to be satisfied running this project on CPU on four machines, doing about 4-6,000 credits per day, at 213.76 credits per WU regardless of which machine. Have a great Christmas holiday.
37) Message boards : The Lounge : Really really want to change email address. (Message 46844) Posted 18 Dec 2012 by mitrichr Post: I want to change my email address for all of my projects. I understand that this can foul up the CPID and lose me all of my credits. Has this maybe by now been somehow overcome? I have never ever understood the use of an email address as a user id. People change email providers the way they change their underwear. Why can we n ot have a simple user id/password system like almost all web sites?
38) Message boards : GPUs : Milky Way fails on my GPU (Message 46843) Posted 18 Dec 2012 by mitrichr Post: Running BOINC 7.0.28, i7-3930k, 16 gigs DRAM. Twin GTX670's but with SLI enabled (both BOINC and my builder Maingear want Dev 0, so this is the best solution). I am set in cc_config to ignore dev 1. I only run one GPU work unit at any time. I am succeeding with GPU work with Einstein and SETI, but many many immediate 1 second failures on Milky Way. I took this to their forum, lots of people tried to help; but to no avail. I am succeeding with Milky Way big time on CPU work units, 4-6,000 credits a day. But, you know, I would like to run GPU for this project.
39) Message boards : Questions and problems : Rapidly being put out of BOINC by CPU heat (Message 46706) Posted 10 Dec 2012 by mitrichr Post: Jord- I think that I just eliminated the chill pads. All of mine are Targus. All USB powered (AC adapters available, but hard to come by). Also, after a while, they just want to quit. I blow out dust from the fans, and they work for a while. So, I still had a Hi Fi Boxer fan from my analog music days. It cooled the big tubes in a Fisher 500 receiver, which is long gone. I put the fan next to a laptop, got rid of the chill pad, and elevated the laptop with four Roller Blade wheels (what is a 71 year old to do with Roller Blades?). Using the battery case in the back, the laptop is elevated 40 mm in back and 30 mm in front. In ten minutes, the bottom of the laptop was just plain cooled off. So, I just ordered three more similar fans, with AC power adapters for my other three laptops. The fans are less money than are the chill pads. I bet they last longer. The one I am using is 30 years old and has sart in my cellar for about 15 years. Happy season to you, Jord, and to all readers.
40) Message boards : Questions and problems : Automatic Temperature regulation (Message 46626) Posted 6 Dec 2012 by mitrichr Post: I tried 6.3X on an i7-2720QM. Total failure again. W/O BOINC and TThrottle the machine runs in the 40's C. I installed TThrottle prior to BOINC. The scan ran up into the 80's C and settled back near the preset 50 C. Then I installed BOINC and the temps blew right through to the high 80's. With temps w/o BOINC in the 40's, I see no reason to question the thermal paste.
