Pentium D Processors?
(Message 162167)
Posted 2 Sep 2005 by  Shaktai
Post: Pretty sure the answer is in the L2 cache. the more you have the faster you can crunch Seti, thats not necessarily true for other projects though. Seti calculations have long favored larger cache. I saw some preliminary numbers on and AMD 4800 with 1meg of L2 per core, and it was "much" faster then my 4200 with only 512k per core and would easily be faster then my Pentium D840. Somewhere I thought I saw some numbers on an AMD 64 4400 which is the same as my 4200 but with larger 1 meg L2 cache per core. Trying to find those numbers again to see if the larger cache really benefits it. |

Validators on holliday

Post: I have had work units validating. All of my outstanding work units that I checked, just haven't reached quorum yet. However, those that had reached quorum have validated, including a few that were downloaded and crunched since the outage. |

Pentium D Processors?
(Message 161822)

Post:
There are two different Pentium D840 chips. The one Tom's Hardware was referencing is the Pentium D 840EE. The only difference is the EE has HT. Mine doesn't have HT. The D 840EE might show a 10-15% improvement from the HT. Remember that it is still just 2 3.2ghz cores with 1 meg of L2 cache per core. The HT will make it a little more effecient. The AMD's do not have Hyper Threading as that belongs only to Intel. |

Posted 2 Sep 2005 by Shaktai
Post: Okay, now that I have gotten some work units uploaded from my AMD 64 4200+ dual core I can compare it against my Pentium D 840. Here are the results. AMD 64 4200+ 4089.55 seconds per work unit average per core. 68.16 minutes or 42.25 work units per day with both cores running. Pentium D 840 3378.40 seconds per work unit average per core. 56.30 minutes or 51.15 work units per day with both cores running. Both are respectable. However, on Einstein which favors the AMD the tables are reversed. AMD 64 4200+ 20498 seconds or 8.44 work units per day. Pentium D 840 26513 seconds or 6.52 work units per day. |

Mac OS9 Cutoff Date?
(Message 161798)
Posted 2 Sep 2005 by Shaktai
Post:
A common source code is used for all the platforms. Because Mac OS-X is a Unix Kernal, it is easy to compile that binary. However, for Mac OS 9 and earlier, the code would have to be re-written from the ground up, and there just aren't enough "people" resources to do that effectively, in relationship to the expected gain in users. It will be sad to lose those folks that still run OS-9 or earlier, but the development team has too many other issues that must be addressed at this time, that affect a far greater number of users. If we were to put it into financial terms, it just isn't "cost effective" meaning it would cost more to do then would be gained. |

work unit amount not showing correctly
(Message 161796)
Posted 2 Sep 2005 by Shaktai
Post: The results showing from SETI Classic are a "snapshot" from last March. They are not updated real-time. After SETI Classic closes, a final snapshot will be taken and will show your total SETI Classic units. Don't worry, they aren't lost. |

Faster core client needed
(Message 161795)
Posted 2 Sep 2005 by Shaktai
Post: There is also a "proven" altivec compiled application that has provided consistent quality units known to validate. It has been used successfully for several months now. It is hosted by Team MacNN, but is available to all Mac users. Got to: http://members.dslextreme.com/~readerforum/forum_team/boinc.html Scroll to the bottom of the page and you will see a SETI optimized client there that will reduce time on G4 and G5 processors by 40-60%. There are not any optimizations available for G3 processors. Of course, if you don't already belong to a team but are interested in joining one, Team MacNN is the friendliest and the best. We also have optimized BOINC compiles on that same page. They are useful for improving your claimed credit when used in conjunction with the optimized SETI app. |

Slowly Uploading

What Broke?..Cogent , or...
(Message 160408)
Posted 31 Aug 2005 by Shaktai
Post: Nothing's broke, there are just a few hundred thousand computers all trying to connect at one time. Periodically I'll manage to upload or download something, but for the next few hours it will be the luck of the draw. Should probably be clear by morning. Just leave your client ready and it will periodically try to either upload or download a unit or two. Plenty of bandwidth, just too many computers for the servers to handle at once. |

A Conversation with David Anderson
(Message 159726)
Posted 30 Aug 2005 by Shaktai
Post: Dr Dave is a very busy man. He not only works directly on some of the development, but also oversees much of the adminstration, fund raising, publicity, etc. While it would be enjoyble if would post here once in a great while, he does deserve some time off. Like many adminstrators, he has to sub-delegate some of his duties to others. Can't be everywhere all the time. Cut the man some slack. Most of us here could not work his schedule, or accomplish what he has accomplished. |

Post: For those who haven't read the technical news or don't quite understand it, there is a very good chance you will get credit for work units that are past due now, but can't be returned until the system comes fully back up. The SETI team is doing everything possible to make that happen. |

Please turn on splitters
(Message 158985)
Posted 29 Aug 2005 by Shaktai
Post: Since they have started ramping up the splitters, I am wondering if they are planning on opening up by end of day tomorrow. No guarantees, but it seems that they may consider it an option. The splitters are now generating a lot of new units, at about twice the speed the validators are running. Well tomorrow is a work day, I'll just let things take their course and check it out after work tomorrow. Good night all. |

Post: Well, I'm going to guess that the project team feels they will be able to soon start sending out work again. Probably they had a pretty good sense of how long it would take to generate the work. By tomorrow morning Berkeley time, they will have a pretty good cache. |

SETI@home Science :
I hate BOINC deadlines.
(Message 158942)
Posted 29 Aug 2005 by Shaktai
Post: And what does any of this have to do with "Science"? Looks like all of the people that joined SETI in 1999 hate BOINC... As already stated, speak for yourself. I like SETI BOINC, despite its growing pains which are no worse then the growing pains of Classic in 1999. (snip) I hate BOINC...I hate boinc...I hate boinc...I hate boinc...I hate boinc and that will never change until BOINC changes! Reminds me of a 6 year olds temper tantrum. From a scientific perspective, BOINC provides a much more flexible platform, that can adapt to scientific growth. SETI must evolve and grow. SETI Classic isn't capable of managing that growth or the need for more advanced Science. |

Post: ... but these are times where most people seem a bit on edge around here. I think we are all anxious for things to get back to normal. I can only imagine how the Berkeley team feels. They are probably more frustrated then we are, but being scientists, know the value of not letting emotions control your thoughts. Step back, analyze the situation, evaluate options and then try again, hoping that you are making the right choices. Don't worry, I didn't take your post personal. It was a reasonable comment. -------- Thomas Edison -- 1. I have not failed. I've just found 10,000 ways that won't work. 2. Opportunity is missed by most people because it is dressed in overalls and looks like work. 3. Genius is one percent inspiration, ninety-nine percent perspiration. 4. Just because something doesn't do what you planned it to do doesn't mean it's useless. 5. If we all did the things we are capable of doing, we would literally astound ourselves. -------- |
