1) Message boards : Number crunching : Invalid rss feed (Message 72035) Posted 9 Jan 2012 by Bok Post: Causing issues with vBulletin though some readers handle it ok. Checking it with w3 shows it is certainly invalid - http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fboinc.bakerlab.org%2Frosetta%2Frss_main.php Can this be corrected at the source ? Regards Bok
2) Message boards : Number crunching : Facebook App for milestones posting (Message 63114) Posted 1 Sep 2009 by Bok Post: yep. that's it. I can 'fake' one for you if you'd like to see what it looks like :) How about your 100 in Collatz from a few weeks ago.. Let me make it today temporarily... Done, you should see a post on your wall.. might need to refresh as I find your own posts take longer to show up than others.. Bok
3) Message boards : Number crunching : Facebook App for milestones posting (Message 63112) Posted 1 Sep 2009 by Bok Post: I've been working on a Facebook application which when signed up for will make a wall post for any of the BOINC milestones you pass. This is not just Rosetta specific but for any of the projects for your CPID If anyone is interested and has a facebook page, then please feel free to try it out here Milestones are all based on the ones I generated at Free-DC stats and these can be updated to add new ones on request easily enough, though I think they are fairly comprehensive. I have 28 people using it so far nd in the past 2 weeks or so it's been working well. In the next few days we hope to get the initial page fixed up somewhat but it's fairly simple to follow I think as is. Basically, you accept the application (standard facebook) then follow the instructions on the page itself, by entering your CPID and then going to the link to allow the app permission to post to your stream - if you've done it all correctly you'll actually see your recent milestones on that page anyway. From then on, any day that you pass a milestone in Rosetta or any BOINC project for that CPID it will post it to your wall, also for combined milestones too. I'm 90% through coding of posting your team milestones as well, though may make that optional. It has been fairly interesting writing this app and I see many future possibilities for it also, though many of them will require the co-operation of the various BOINC projects and possible extensions added into the BOINC framework code.. For instance, posting when you get the lowest energy in a Rosetta molecule, or when you reach a new badge level in World Community Grid.. Bok
4) Message boards : Number crunching : Team Points STOLEN!!!!! Over 6 Million Points! (Message 54715) Posted 29 Jul 2008 by Bok Post: I went ahead and requested foundership transfer on Nano-Hive back to me at which point I'll rename the team back to Free-DC.. Still can't do Ralph as I can't get into my account...
5) Message boards : Number crunching : Team Points STOLEN!!!!! Over 6 Million Points! (Message 54422) Posted 10 Jul 2008 by Bok Post: I can't seem to get into my Ralph account at the moment so I'll have to post this here.. To the admins: Can you restore the Free-DC team in Ralph@Home like you have done with the Teddies team here ? Thanks Bok
6) Message boards : Number crunching : Thread Delete: Why I am pulling my machines out. (Message 23514) Posted 19 Aug 2006 by Bok Post: What about Groupee's message board application (formerly Infopop)? I know Ars Technica uses them. Anyone have experience with it? I would go with vBulletin personally. There is a license you have to purchase but it's not that much in the grand scheme of things. The signing up and moderating functions are pretty extensive and not that difficult to use.
7) Message boards : Number crunching : Thread Delete: Why I am pulling my machines out. (Message 23292) Posted 19 Aug 2006 by Bok Post: David, it seems some of the problems are due to the nature of this message board (i.e. it's not great). Would you be interested in having message boards hosted at Free-DC in the same way we do for SeventeenorBust and a number of other projects ?? It's all using vbulletin. I'd be happy to do that and set you all up as moderators etc.. Bok
8) Message boards : Number crunching : How to Claim 500 Credits? (Message 17448) Posted 31 May 2006 by Bok Post: Looking at top particapants, some person has 144k average credit. That must seriously screw up the tflop measuremnent for rosetta@home. Why? You must be referring to DDTUNG, who has somewhere in the region of 80 dual core opterons + 30 or so dual xeons@3Ghz + other assorted P4's. He is legitimately processing that amount per day.. Bok
9) Message boards : Number crunching : Just a heads up for you folks. (Message 17442) Posted 31 May 2006 by Bok Post: Of course we know, there is a limit to how much one team can produce though. With XtremeSystems having way more members, it's difficult to match their numbers. Maybe if we managed to get everyone running Rosetta we could, but that's not how we do things... As for the whole benchmark and optimized clients thing. Well what started as a way to level the playing field between windows and linux has got out of hand somewhat. I'm all for having Rosetta implement there own benchmark to level the playing field, though in my mind the playing field is already level. The clients are readily available to all those who wish to use them. That being said, I see no way you could benchmark a xeon at the levels some of those anonymous clients were showing. Fastest I've seen yet, that I believe, is the Conroe at 3.1 which was giving 7K/26K. I have a few myself in the 5K/15K range (all dual core opterons). My DX 3.6 (800FSB) is pretty close to that with the appropriate client. Bok
10) Message boards : Rosetta@home Science : 7 WUs returned in error by computer 131283 (Message 10410) Posted 3 Feb 2006 by Bok Post: Carlos, the difference in versions is, I believe, just a fix to a windows only bug. There was no need to release this version for linux. Most of my machines run Rosetta under linux, a mixture of Gentoo and Redhat with zero problems.. Bok
11) Message boards : Number crunching : Recent Average Credit (Message 9252) Posted 18 Jan 2006 by Bok Post: Speaking from experience, I wouldn't give Informix the time of day. Mysql doesn't do some of the things Oracle/DB2 do, but if it's set up correctly, for what Boinc needs, it is just as fast. Benchmark figures for Oracle and DB2 are almost always done with cutting edge raid arrays, more often than not using fibre connections whereas mysql benchmarks are usually on either single channel or perhaps a simple RAID 5. As was mentioned earlier in the thread, databases are usually constrained by IO to the disk (or they are designed very badly). Lots of memory helps with cacheing (along with a properly tuned DB to make use of it) but this is exactly the same as enterprise databases. I've seen Oracle databases which perform horribly on 8-way sun machines with 16Gb ram because the SGA has only been allocated 512Mb. Bok
12) Message boards : Number crunching : Recent Average Credit (Message 9219) Posted 17 Jan 2006 by Bok Post: Just to add to this, Everyone is correct. I'm also a part time DBA (Oracle & DB2) and I totally understand the reasons for not doing multiple lookups and how boinc stores the data. RAC in this case is the only way to do this 'cheaply'. I think it's also why boinc actively encourages 3rd party stats. Many years ago when I first started writing stats, I used to have a table which was keyed on name + date, this rapidly got very large which is not really a problem as disk is cheap. However the displaying last 30 days of data became very cumbersome as it would involve at least 30 selects. I made a decision after asking for input to only store the last 30 days of data. What I additionally did was to store it all in a single row, which makes the updates slightly more expensive, but the display of the data is then much less costly.. including finding averages, last x days etc etc. FYI, parsing the XML stats and updating all the info, calculating movements/milestones etc for R@H takes roughly 12 mins on my stats box. On a Dual xeon 3.6 I have at home it takes only 7 mins. The scripts are all perl based and a mysql backend. Bok
13) Message boards : Number crunching : Recent Average Credit (Message 9098) Posted 15 Jan 2006 by Bok Post: Thanks, I only just added the host stats for Rosetta, so there is still some work to do on that.. Personally I also use Zain's stats for some things I don't handle well :) Bok
14) Message boards : Number crunching : Recent Average Credit (Message 9088) Posted 15 Jan 2006 by Bok Post: I calculate 7-day averages here and if you go to the individual user page it has a 28 day average too.. I thought Zain did that too, but I might be mistaken. Bok
15) Message boards : Number crunching : BIG credit problem! User has a zillion credits! (Message 8694) Posted 9 Jan 2006 by Bok Post: Networking off doesn't affect the floating point scores though... check them out :) Bok
16) Message boards : Number crunching : BIG credit problem! User has a zillion credits! (Message 8689) Posted 9 Jan 2006 by Bok Post: Not quite the same thing, but when looking at the top computers today, #1 in RAC is http://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=126650 Not even any of the optimized clients come close to that kind of performance... There is another dual xeon a little further down with almost exactly the same specs, possibly the same user, though it's impossible to tell. Bok
17) Message boards : Cafe Rosetta : XtremeSystems Stats (Message 8017) Posted 30 Dec 2005 by Bok Post: I think this is the case, I'm showing that your user joined the team with close to 9000 points already, the team does not get these points as they weren't crunched whilst on the team... stats here Bok
18) Message boards : Number crunching : Moderated messages moved here (Message 7556) Posted 24 Dec 2005 by Bok Post: And you aren't attacking Free-DC now ? Even a little?
19) Message boards : Number crunching : Moderated messages moved here (Message 7412) Posted 23 Dec 2005 by Bok Post: Well, then you've lost any chance of respect from me.
20) Message boards : Number crunching : Moderated messages moved here (Message 7397) Posted 23 Dec 2005 by Bok Post: Yes Paul, but a moderator should show a lot more care in replies than the day to day user. They have to remain above any condescension. Bill's replies show quite a bit of exasperation in my opinion which should never be the case for a moderator. Cases of "shouting" by uppercasing words. This quote from one of his replies in particular does not read well at all (IMO).. Several issues here. "Time clock just stops" is a new problem, if it's really a problem. Of course, with zero information from you on this, even though you have had it occur "over 100 times", it is hard to give any information. This is your FIRST posting on the issue. When the clock stops, is the status of the result by any chance "preempted"? And please, explain why a _reboot_ would be necessary? Are you sure that the problem isn't the OPERATING SYSTEM locking up, maybe because you're way overclocked, and not anything to do with Rosetta? If the problem is NOT as you describe, if the problem is instead the one being discussed in this thread, then you have had over 100 examples of something the project is asking for help to solve, yet you have not given the project any assistance. Instead you prefer to complain about the WU _names_ (in another thread) and now blame the project for what sounds like a problem on your end, or a total misunderstanding of the way the system works. In general, as much as I'm sure the project appreciates your (considerable) computer power, if you are only in this for the "points per day" and not to help the project, and expect the project to cater to your whims and jump to solve your problems, while you are unwilling to give the project any help in solving these problems, my _personal_ opinion is that you WOULD be happier with another project. Somewhere that the science would be less important, and you could get all the credits you want. I would suggest SETI. If you are here to volunteer your CPU time to a worthy effort, and not just to earn credits, then you need to start asking questions instead of jumping to conclusions. We are all happy to help anyone with a problem. Moderating can be difficult, I've done it for years and have made mistakes too, but you have to keep a cool head and remain impartial.. my 2p worth..
