Myslím že nejvíce dává nyní jednoznačně Cosmology, kde není problém získat se čtyřjádrem víc jak 12.000 kreditu / 24 hodin

No ked sa pozriem do tabulky, tak to v Cosmo pre Xeony vychadza cca 8 tis. pre Quady nieco cez 4,5 tis.

kredit bol po burlivej debate zdvihnuty z 2,17 na 4,06. tak uvidime ako to nakoniec dopadne 
a kolko milkyway stratila cruncherov.

Ten RAC ještě nebyl moc ovlivněn krátkými jednotkami z posledních dnů. Například já dostal za poslední 2 dny víc jak 13.000 kreditu a dalších skoro 100 (tedy potenciálních 10.000 kreditu) mám v Pending. Přitom RAC stále jen 1054, takže dle RAC se na výkony koukni tak za 1-2 týdny a nebudeš se myslím stačit divit, pokud s tím do té doby něco neudělají.marpes napísal:No ked sa pozriem do tabulky, tak to v Cosmo pre Xeony vychadza cca 8 tis. pre Quady nieco cez 4,5 tis.
Omlouvám se že to píši zde trochu mimo téma, ale vhodnější téma jsem zde nenašel, kdyžtak to přesuňte.

najkratšia WU cosmology mi trvala 45min... 100cr/ani nie hodinu, nieje zle..

No potrebovali by sme este jeden stroj na tento projekt a coskoro by sme sa mohli
dostat do prvej desiatky, takze potencialne by tam smerovali TSP a Milky Way.

Jestli nepobezi Cosmo, nebudeme me bavit Einstein a ABC, tak bych tam par desitek jader pristi tyden zase prehodil...

Dnes som porovnaval 32 a 64-bit aplikaciu a 64-bit je o 44 % rýchlejsia.
Na Ubuntu 7.10 i686 resp. x86_64.

Damn - Milky je na suchu a ja si nedal povoleni prace, ackoli mam Einstein jako zalozni.
Takze par desitek jader bylo na suchu...ani nevim, jak dlouho. No povolil jsem praci pro Einstein, ale uz je skorem konec pracovni doby...
Hmm, a kdyz to ted maji BS jako PotM, takt o bude hezky streess-test pro Milky.

Uz su ulohy, len neviem dokedy. Vacsinou po 2 - 4 dnoch je na par hodin sucho, tak
ja davam CPDN alebo Cosmo.

info od Travisa:
i've started up a new (really big) batch of searches. these should keep you happily crunching for a long time (i hope)
...
it's a new set of star points to crunch on. Nate has been running into some problems with using conjugate gradient descent on different data sets (its converging to a local minima), and interestingly enough we were getting the same problem with the genetic search. we're trying out a new set of data, and tweaked our genetic search a little bit (we think some of the parameters in the model aren't orthogonal -- which is screwing things up). so these new searches on this new data should help us figure out the problem.

Hlavne, ze je prace a snad nejakou dobu vydrzi.
A tohle je take dobre:
A tohle je take dobre:
Travis napísal:the WUs might be a little longer, because the star file is bigger. more stars to calculate the likelihood would increase the time of calculation.
basically, the WU does two parts, the first calculates an integral over the volume of space we're dealing with. this is pretty much fixed -- we can set how fine grained it is, but once thats fixed it should take the same amount of time.
the second part calculates the likelihood of the calculated model being a good match to the data. this is usually pretty quick as it's done in linear time over the stars in the stars file, and not nearly as computationally intensive as calculating the integral. so when we increase the star file you should see the WUs take slightly longer.
this is also the reason that the progress bar is a bit wonky, when it changes speeds that means it's stopped calculating the integral and started to calculate the likelihood.

Vypada to, že Milky má nějaké trouble.
