Ja nepoužívam app_info.xml a load na GPU sa pohybuje medzi 86% a 95%. Teraz je verzia 2.04, čas výpočtu okolo 640 sekúnd. Predtým s verziou 2.00 to bolo okolo 770 sekúnd. Mám HD4870... optimálne cmdline v app_info.xml môže závisieť od typu karty...

Pri pretaktovaní grafiky môžeš skončiť napríklad takto. Nepadajú mu všetky jednotky, iba niektoré (možno to súvisí s GPU loadom). A jeho wingmani sú potom radi, že musia čakať na tretieho. Ja som mal to šťastie 4 krát s týmto fetošom. A na fóre dokonca uvádzajú, že niektoré karty, ktoré výrobca taktuje nad referenčný takt, treba dať na nižší takt, lebo inak vracajú chybné výsledky...

Taktol som 4770 na 800 MHz core, 820 MHz GDDR5, WUs su validovane OK, zlepsenie
je cca. 10 %, najlepsie casy okolo 635 s. Spotreba karty je taka ista ako na def.
Dnes som to taktol na 830 core, 850 mem., spotreba stupla o 5 W, casy budu
az po jenom dni, ale myslim ze uz nejake vyrazne zlepsenie nenastane.
Ked viete kde je uzke hrdlo pri tychto vypoctoch, tak to sem hodte.

Tak, dalsim OC na 875 core a 895 mem., sa mi podarilo stlacit casy na 587 s,
co dava 86400 / 587 * 550 = 81000 points p. d.
WUs su validovane OK, uvidime ako to pojde dalej, tie karty su schopne
bezat na 950 / 1200 MHz.

Zaujimave vysledky po OC HD5870 najdete tu:

Skusali ste niekto novu opt. app. 2.05b ?

Beha mi od vcerajska, zatial bez problemov. Casy sa o nieco znizili.

Mne tiez 2.05b funguje dobre. Ziaden cmdline a GPU bezi okolo 97%.

Ja som mal s 2.04 opt. 99 % a teraz mam s 2.05b bez cmd 91 %. Zaujimave.

Je vonku 2.06, skusal uz niekto opt. app ?

Back Online; ATI 2.05 Applications Deprecated
October 19, 20:42 CST
The project is back online after the outage this weekend. If you are using an ATI GPU and have not converted to v2.06 yet, you may want to do so now. Any WU that crashes the validator will be deleted. No credit awarded. After having manually fixed several hundred in the last 24 hours, I am tired of fixing. If you are using the standard ATI apps, the ATI 2.06 app has probably already downloaded and your have nothing to do. If you are running an app_info.xml and have not yet upgraded, you may want to do so as soon as possible. If the 2.05 results continue to crash the validator, I will change the validator to reject any 2.05 results so that the project does not crash again next weekend.

Over 1 Million Workunits Served
October 20, 15:37 CST
Give yourselves a pat on the back! Collatz participants from 72 countries have now completed more than one million Collatz workunits, returned more than 3.5 million results and, according to BOINCstats, earned over a billion BOINC credits. Thanks for contributing!

Uz niekolko dni nejde validator.

Linux 32-bit CUDA Application Added
October 26, 12:41 CST
The CUDA app for Linux 32-bit has been added to the Optimized Applications page and the app_info.xml for the 64-bit Linux CUDA app has also been corrected. (Thanks Crunch3r!)
http://boinc.thesonntags.com/collatz/power_apps.php
Takze Linuxaci, ktori maju CUDA capable kartu, uz mozu smelo crunchovat.
Dufam, ze za par tyzdnov bude aj Linux + ATI.

No asi som sa tesil marne.

nVidia 190.38 or later drivers for nVida/CUDA GPU processing and a CUDA capable GPU
Ak vidim dobre, tak mam 190.42 drivery, CUDA capable GPU,
http://www.nvidia.com/object/cuda_learn_products.html
ale pise mi tam, ze nemam nejaku kniznicu. Tak co je zasa zle ?

v adresari ./BOINC/projects/boinc.thesonntags.com_collatz si sprav symbolicku linku

libcudart.so.2 -> libcudart.so.2.2

Mne to slape bez problemov na GeForce 8600GT (cca 2 hodiny 1 jednotka).

Este si over ci mas spravnu verziu app_info.xml - crunch3r ju 27-ho updatol:

<app_info>

ja som loadol toto, rozbalil do collatz adresara. v app_xml pridal jednu dvojku:
<name>libcudart.so.2.2</name>
<file_name>libcudart.so.2.2</file_name>
a nakopcil libcudart.so.2.2 do /usr/lib64 a este som ju nakopil pod menom libcudart.so.2
a uz to ide, lenze nejako pomaly, ale ja mam 8400GS, co je srotovnik

Vidim Palo, ze si sa ponukol testovat ATI for Linux. Ako to funguje ?
Ja mam Ubuntu 9.04 x86_64, dal som tam 9.10 ATI drivery, a 6.10.17 tak dufam, ze to staci.
Zatial mi neposlalo ziadnu binarku, ani nikde na fore nevidim link na nejaky taz.gz file.
