1) Message boards : Number crunching : 100 Teraflops (Message 60866) Posted 28 Apr 2009 by Charlie Abrams Post: I think the Teraflops are plummeting for a different reason. I'm getting "no work sent (but there was work for other platforms)" - all of my machines are getting this message. My average is dropping fast, but I didn't do anything and the machines only run ROSETTA. Is there an upgrade that I don't know about that has to be installed manually to run new units?

3) Message boards : Number crunching : Leader boards all the same? (Message 49340) Posted 3 Dec 2007 by Charlie Abrams Post: Until very recently, the different leader boards showed rankings correctly. Now all of the leader boards show the same list, which is for "all teams" rather than subsets. Can this be fixed? Thanks,

(Message 31572) Posted 22 Nov 2006 by Charlie Abrams Post: Two words: Extra credit Two more words: College rivalry (as has been noted by others) My students are joining up to earn extra credit (10 pts out of about 800 for the course). We're just barely outpacing Vermont Technical College (VTC) for second place in the Junior College rankings. I think the students enjoy this competition and are motivated to beat TEAM JESUS (have you seen the picture of their founder??? hahahaha all in good fun) One thing that could help recruitment is creating more categories for teams, like leagues - the small 4 year colleges can't compete with the state schools for number of users or computers, and should have their own league. If my team (Truman College) had to compete with the 4 year schools we'd even never be in the top 100 and would not be as motivated to move up in the rankings. Perhaps there should be a category for Liberal Arts Colleges and/or a division among East Coast/West Coast/Flyoverland universities? It would be great if you could list your team on several of these leagues at once, so you'd have a chance to compete against all groups in the same city or region, as well as all groups that are similar in other ways (4 year schools, etc.)
5) Message boards : Rosetta@home Science : What is that protein? (Message 30729) Posted 6 Nov 2006 by Charlie Abrams Post: Thanks Chu, I feel bmud, I mean dumb. I guess there are so many pdb files now that you can even get a hit by switching letters around. ;-)
6) Message boards : Rosetta@home Science : What is that protein? (Message 30717) Posted 6 Nov 2006 by Charlie Abrams Post: For this docking WU am very curious - what the is large horseshoe shaped protein with alpha helices on the outside and beta sheets on the inside? The WU has "1DJF" in the header, which comes up as a single alpha helical strand in the PDB file. Is it ribonuclease inhibitor 2bex?
7) Message boards : Rosetta@home Science : New graphic feature in update V5.32 (Message 30379) Posted 31 Oct 2006 by Charlie Abrams Post: Hugothehermit, Perhaps I can give it a try: Phenylalanine (nonpolar) = hexagon Tryptophan (nonpolar) = hexagon and pentagon sharing one side Lysine (polar, charged) = long zig-zag Tyrosine (polar, uncharged) = hexagon with a stick attached Histidine (polar, charged) = pentagon Most of the others are impossible to distinguish unless colors are used to represent the individual atoms. If you are able to find even the ones above, you're doing really well.
8) Message boards : Rosetta@home Science : New graphic feature in update V5.32 (Message 30373) Posted 31 Oct 2006 by Charlie Abrams Post: Would it be possible in the next version to color the side chains according to polarity? For example, D,E=red; K,R=blue; C=yellow; A,I,L,M,F,P,W,V=green; and G,S,T,N,Q,Y,H=orange? Maybe this is too many colors, but I know it would be fun to watch.
9) Message boards : Rosetta@home Science : A thought about method (Message 30000) Posted 25 Oct 2006 by Charlie Abrams Post: I'd be interested in the RMSD between my computer's prediction and the overall lowest energy prediction - in other words, how close are all of the predictions to each other? As I understand it, two structures may be both exactly 1.0 RMSD from the correct structure but could be much more (or less) than 1.0 RMSD from each other.
10) Message boards : Number crunching : Archieve of newbie Q&A (Message 29672) Posted 20 Oct 2006 by Charlie Abrams Post: Thanks BennyRop, that makes more sense. I don't know why the Mac didn't report results for 5 days. It was connected to the internet and did not show any errors in the message window, and it was running the BOINC client.
11) Message boards : Number crunching : Archieve of newbie Q&A (Message 29615) Posted 19 Oct 2006 by Charlie Abrams Post: I just added a second computer, and when it reported its first results my RAC went DOWN - was about 43 and dropped to around 32. Was this because the new computer average credit is lower, so my total average went down?
12) Message boards : Number crunching : Archieve of newbie Q&A (Message 21408) Posted 30 Jul 2006 by Charlie Abrams Post: Thanks! I have another problem - I have not been able to update my team information. I want to change our type from Unknown to Junior College, but when I click update nothing changes. Do I have to have more than one member of the team in order to be able to change the info? Any suggestions appreciated. Charlie
13) Message boards : Number crunching : Archieve of newbie Q&A (Message 21305) Posted 28 Jul 2006 by Charlie Abrams Post: How common is credit cheating in BOINC? Should I calibrate my computer by running a CPU benchmark, and if so, where do I enter the calibration results?
