Simon I wish you Luck! If you want a reference they you can give them my lowly al.setiboinc (at) Gmail.com addresss. I will be happy to add references and explain what is happening and how they "could" gain inroads into a "Sun Shop"... From reading various BOINc Developers Froums, there are inroads into detecting the type of CPU to allow delivoring the correct Application according to the CPU type... So Progress can be made, IF a Few people Try! Oi, 649 posts... Please consider a Donation to the Seti Project. |

I don't know if this argument holds water. IMO their validator should take care of this. There are other sources for erroneous results: - faulty hardware - errors in the official apps Regards Hans |

Well, the whole problem for Akosf and with the Einstein apps is that they're closed source and he had only compiled code to optimize using manual assembly tuning. The Seti@Home and BOINC clients are both GPL, the Einstein ones aren't. So I'm really not surprised (but sad for Akosf) that they decided to disallow (some of?) his apps. And yeah, if you distribute a program, you should have a license for it...RTPatch isn't open source or free - but that's never stopped anyone from distributing it, heh...if you have a license, you're allowed to, as well - no idea whether he had one or not. There are free alternatives that are easy to use (even GUI-based). So anyway, I've always just crunched for Seti, and that won't change anytime soon. No disrespect to other projects, but I'm staying right here :o) Regards, Simon. Donate to SETI@Home via PayPal! Optimized SETI@Home apps + Information |

Brian A portion went into the S5 Application, now he is looking at what is happening and going to work... So If you look and read there are many people working on it... For Seti that work is happening in Seti Beta... A litlle OT, but Akos had to pull his latest patches because of validation issues. Please consider a Donation to the Seti Project. |

A litlle OT, but Akos had to pull his latest patches because of validation issues. A combination of issues. In the testing, some patches indeed produced invalid results and this was "live testing" so those WUs were being uploaded and failing validation. Biggest issue appears to be that Einstein proj. mgt. only recognizes "official aps" as sanctioned for doing actual science. Unlike S@H, Einstein tightly controls modifications to the applications. Akos's previous S4 opt. aps were released as Official "Betas" after approval of project Mgt. HIs last validating patch, S5T0712 was @ 35% faster than the std application. It would seem there wasn't unanimous approval of his efforts w/ the project and he was requested to tell everyone that "the party was over"....rather abruptly w/o any warning. Needless to say, folks while certainly appreciative and supportive of Akos, are pretty peeved at E@H project Mgt. They're still adjusting to very same things we all went through with migration to Enhanced in May ie. dramatically increased crunching time and credit methodology changes. Many of the comments and discussions on their board right now will look quite familiar to S@H forum participants. |

Hans Sorry, You forgot one... Thier Validator with the new Appilication could also be an issue... In Alpha/Beta it is a Bug! After Release it is an "un-documented feature."

Hans, I believe that too. While you're at it, could you mention that I want a couple of woodcrests NOW :o) Regards Hans |

Simon Exactly! So that's why I'm trying to spearhead a friendly effort at getting us all to enjoy the potential benefits. I would be glad if I can include you in my references, thanks for offering. I really don't know what to do first right now, good thing I still have time off from work (anyone looking for a good NT/Linux/Slowaris/BSD sysadmin / web developer / multi-os wizard? *grin*). Seriously though, I'm really trying hard to make everything I do as transparent as possible to avoid any possible drama. So far, it's going well :o) Regards, Simon. Donate to SETI@Home via PayPal!

Hans, I believe that too. Lol. Yes, yes. A couple of Woodcrests to do the heavy lifting, and a couple of Core 2 Duo X6800s to play with. Er, there goes my mind :o) Wouldn't we just love that. Regards, Simon. Donate to SETI@Home via PayPal! Optimized SETI@Home apps + Information |

HI simon Hi Pappa Hi Hans Pappa: Like I said, I believe he paid for them :o) Enough drama. Some old history from ..... 30 Nov 2005 ... 13:37:48 UTC ...
the above was copied from here .............. Posted .. on ... 30 Nov 2005 13:37:48 UTC http://setiathome.berkeley.edu/forum_thread.php?id=23410#199350 Regards Byron |

The first thread used by TMR when trying to optimize a windows version with the Eval version is called "Compiling faster Windows client with Intel C++ compiler (and fftw?). It's an interesting read. This development sounds much like that one. TMR discusses licenses and such, there are even links to intel compiler forums, and many things that KWSN - Chicken of Angnor might find helpful. Also, in the follow up thread called 2nd: Compiling faster Windows client with Intel C++ compiler (and fftw?), TMR Identifies the person/s who set him up with the license in this post. Hope this helps tony |

Thanks a lot for the links! Lots of useful info. Huge threads, too :o) It'll take me a while to skim over them ... Regards, Simon. Donate to SETI@Home via PayPal! Optimized SETI@Home apps + Information |

and the third thread is 3nd: Compiling faster Windows client with Intel C++ compiler (and fftw?) |
Astro Send message Joined: 16 Apr 02 Posts: 8026 Credit: 600,015 RAC: 0 |
and shortly after the 3rd thread came, New Linux client compiled with Intel C++ compiler? |
Astro Send message Joined: 16 Apr 02 Posts: 8026 Credit: 600,015 RAC: 0 |
then, compile a faster linux client using ipp instead of fftw then, Will you make optimized Windows client if I give the source?, then, "Legal' optimized client for Windows, then, Oh heck, just search TMR's post from 383 days ago and sooner, I'll stop the list here, but it continues for a while. tony NOTE: these were posted in chronological order of posting |

OK one more, a shortcut to the posts of TMR are here. I started from the oldest but when I got to something like post 380 or 390 (383 days ago), I quit working forward |

Very true, but then there is the case where 2 "faulty" test versions get teamed up, or a single FTV gets selected as the canonical. Since they went to an IR of 2, there's a pretty good chance that could happen. I think they just want to limit the number of variables present when they post process the MSD at the end of the S5 run.

Hans Dorn Send message Joined: 3 Apr 99 Posts: 2262 Credit: 26,448,570 RAC: 0 |
Yep. With an IR of 2 the chances are pretty high that bad results get validated. It's a pity that there's no offline validator for Einstein. Regards Hans |
