1) Message boards : LHC@home Science : screensaver/graphics bug (Message 23353) Posted 5 Oct 2011 by MatthewBChambers Post: A screensaver can use, however, a very modest amount of CPU cycles (say, 5%), in my understanding. It would be nice to have an individual choice whether to add that small amount of extra cycles to actual scientific computing or to use an attractive and informative screensaver. In my experience, the attractiveness and informativeness of the screensaver for a particular project is key to getting new people interested in BOINC and distributed computing, in the first place, and often in particular projects. If I want to try to interest someone in DC, I have some projects with good, attractive graphics loaded and ready to be shown on my laptop, 'suspending' them one by one (thus making new ones active) to show the person each cool project and some of how it is doing what it is doing. For the biology geek, for example, there is nothing quite like actually seeing protein folding being simulated, something that they likely have only read about. (It might be more efficient, if with less 'authentic' immediacy, to have video captures ready to show, but I've never got around to making any.) I would guess that the small amounts of CPU cycles lost to actual computing by people who choose to use the screensaver are made up for many times over by the CPU cycles contributed by new people joining, many of whom are attracted by the informative, attractive graphics.
2) Questions and Answers : Wish list : Way to end projects gracefully? (Message 20882) Posted 27 Dec 2008 by MatthewBChambers Post: Hi, I was thinking that a useful feature for BOINC or the managers (I have been hoping that gridrepublic will become more useful) would be a way to end projects gracefully, automatically ending projects and detaching clients from them when the projects are no longer running. Currently, I have many projects running, including LHC@home. LHC@home seems to be a temporary project, and will come to an end sometime after the LHC is fully up and running since the project is only for the LHC*s design and will not be used for analyzing data generated by the LHC. Other projects, too, will end or never get past the early phases. My computer, however, was trying to connect to this LHC@home website for months without success: the BOINC manager was unable to connect, and my internet browsers always timed out and gave up when I tried to visit the site. It appears that this site is back, at least temporarily, and there is some new work, but, when this project does end for good, how will we know it is time to detach our BOINC clients, freeing up the space on our HDs and no longer trying to get more work units? PS--edited to remove the mess the forums made of my apostrophe marks. Anyone know why that happens? I did not see a way to fix it under BBCode tags.
3) Questions and Answers : Windows : Stuck at 100%, still Running, high priority. (Message 19653) Posted 22 May 2008 by MatthewBChambers Post: Hi, I have two workunits that appear to be finished but somehow stuck. They say "100.000%" under "Progress" and "---" under "To Completion", but they remain at "Running, high priority". I have restarted the computer, restarted BOINC, and tried to suspend/resume, and to update the project, but the units stay the same. The other info: I am attempting to help test, running BOINC Manager pre-release 6.2.2 (32-bit Windows) on my Vista laptop. It is set to run always.
