About the price of oil
(Message 18515)
Posted 12 Jun 2006 by Dimitris Hatzopoulos Post: I think we need to abandon oil and move on to something else like Hydrogen as oil fields get depleted and it is bad for CO2 emmissions. My point was that until we move to hydrogen or antigravity or whatever, we shouldn't be accepting prices to be set by a broken oil pricing mechanism (as long as one agrees with the facts I've documented in previous posts - and the summary here) Btw, substitutes currently used instead of oil (for economic reasons) are even more damaging to the environment, e.g. photos of Shanghai air pollution from Pearl Tower. You would think it was dusk, but not the case, 14:00 in the afternoon. |

Posted 10 Jun 2006 by Dimitris Hatzopoulos Post: Today I had some time to clean up the draft article parts posted here earlier and post it in my blog (in english): http://dhatz.blogspot.com/2006/06/oil-to-38657-per-barrel.html PS: I had to cut down some of the info I sent here in this thread, as the article otherwise would get too long. Feel free to copy it to people who might be interested. PPS: In my blog, I also have commentary about outlook and my trades on various other markets (metals, stock indices etc), and ofcourse articles on inviting people to join humanitarian DC projects like Rosetta@home, but most articles are written in greek... |

Overall Progress Report

Posted 9 Jun 2006 by Dimitris Hatzopoulos Post: Start with PROJECT INFORMATION AND HELP INDEX and reading the material in the "Science" forum. But to give you an rough idea, until May-06, the project has been running "protein 3D structure prediction" calculations upon already known proteins, in order to improve its methods (about once a week, results were posted in Top predictions link) From May-06 until about late Aug-06, we're running protein structure prediction calcs upon yet UNKNOWN proteins, as part of the CASP7 bi-annual international experiment (these are the Txyz workunits you'll see, e.g. right now I'm running T307, i.e. crunching target 307 protein). Right after CASP7 after Aug-06, project has said they'll run WUs on vaccines (e.g. for AIDS) and on gene therapies (for cancer). |

You probably need two links, one to the publications and another to wikipedia. Keep up the good work, Dimitris |

Connectivity is bad
(Message 18185)
Posted 8 Jun 2006 by Dimitris Hatzopoulos Post: I think it must be due to the spike of 60k users trying to download ~10MB each (new Rosetta executable etc) within a relatively short period of a few hours. Handling 1000s-10,000s of concurrently open HTTP connections is non-trivial and requires some work on Apache sw (and sometimes Linux) config. |

What is the difference between all these protein related projects?
(Message 18147)
Posted 8 Jun 2006 by Dimitris Hatzopoulos Post: I just read your very nice "How-To: Join Distributed Computing projects that benefit humanity" page http://www.hyper.net/dc-howto.html. I noticed that it mentioned "Comments about F@H in Wikipedia suggest that due to recent developments, "Folding@Home approach has become somewhat obsolete"(?). My own measure of useful results would be citations (see later)." Tarx, I'm glad you found the HowTo page useful (it's been viewed about 48k times sofar and I get quite a few emails about it everyday). I have neglected it a bit, since in recent months I've focused my DC-related contributions on Rosetta (writing the Rosetta page in Wikipedia etc) About my F@H comment, I referred to the then-current info on F@H in Wikipedia (you can read about it in W's "discussion" page, with some references, which was wiped out). As I wrote, my personal benchmark would be citations. Anyway, I've posted all relevant info I've collected (e.g. the discussion with mshen in F's forums) in earlier posts in this very thread -here- (and btw I know I should copy it into my HowTo page too). Basically, (having crunched F@H for a couple of years via GoogleToolBar) my current position is the same with Hoelder1in's: "over the years I never really understood how the science done at Folding@home would eventually lead to treatments or cures. With Rosetta@home the connection to identifying drug targets and to drug design seemed much more obvious." |

Posted 8 Jun 2006 by Dimitris Hatzopoulos Post: It's just that from the 60-70.000 Rosetta participants, very few actually check these bulletin board regularly, e.g. my esitmate is that this topic has been read by ~30 people. We could make it sticky for a while, in the hope more people will see it. |

Dial-up
(Message 18006)
Posted 7 Jun 2006 by Dimitris Hatzopoulos Post:
Rosetta@home used to run 8hr WUs by default initially, but longer runtimes led to a larger % of errorneous/aborted WUs (that was before the improvement in the executable and the watchdog thread was implemented). So I guess the current 3hr/WU is a reasonable compromise to accomodate the average cruncher, who doesn't have his PC running 24/7, minimize errorneous WUs and still ensure rapid (~1day) WU turn-around times. The project has said recently that if you have a stable and/or 24/7 PC, the recommendation was to put 8hr/WU. |

Installing Rosetta in high school computer lab
(Message 17877)
Posted 7 Jun 2006 by Dimitris Hatzopoulos Post: Also, any special settings as far as when it turns on that you would recommend for a school environment? because the pcs stay on the login screen most of the day. If PCs stay on login prompt, you should install BOINC as a service (it's an checkbox option during 1st install), so it runs even when nobody is logged on. Note: If you run BOINC as a service and still want to see the Rosetta graphics on occasion, you can go to Services -> BOINC -> "Logon as system accout" and then check the "allow this service to interact with desktop" (this is from WinXP, I guess Win2K is close/same) |

(Message 17813)
Posted 6 Jun 2006 by Dimitris Hatzopoulos Post: Yes, it's awesome! And what's more important, is the "word of mouth" and the multiplier effect (people telling friends, family etc) of this publicity. I hope Rosetta's servers hardware and network link handles the spike in load, I've been noticing delays recently. Perhaps the project could increase WU runtime (from 3 to 4-5 hr) and/or put specific instructions for dialup users on how to do so. |

Rosetta@home Science :
Dial-up
(Message 17802)
Posted 6 Jun 2006 by Dimitris Hatzopoulos Post: It requires a very dedicated person to run Rosetta@home over dialup IMHO. Nevertheless, the "variable WU runtime option" (see http://boinc.bakerlab.org/rosetta/forum_thread.php?id=669#10377) was designed SPECIFICALLY for dialup users and people with capped Internet traffic and can reduce traffic requirement to 1/10th or better. This way you can run a single WU for several CPU hours (default is 3hr, used to be 8hr), up to 4 CPU days. If your PC's hardware is stable, it's a good idea to increase default WU runtime even if you have fast Internet, to use longer WU runtimes (I use 8hr WU runtimes, i.e. each 24/7 PC would finish 3 WUs per day). |

Posted 5 Jun 2006 by Dimitris Hatzopoulos Post: In thread Validation it is explained why Rosetta runs with "initial replication"=1, quorum=1 Basically, when testing a protein, we all get the same raw protein (aminoacid) data (same WU), the difference being the random seed (i.e. the initial instructions to our "virtual explorer" looking for the lowest elevation point). |

(Message 17671)
Posted 5 Jun 2006 by Dimitris Hatzopoulos Post: BOINC client uses the global preferences (e.g. leave-in-mem setting etc) from the project profile which has the most recent date-stamp (i.e. the profile from the project that you modified for last, in your case Rosetta). It can be quite confusing (eventually people will use a "BOINC Account Manager" to manage all their projects from a single location). |
