Pričalo se puno na hwbot.org-u kako će uskoro doći novi program za računanje, pa eto, izašla je beta verzija.

Uglavnom, da ne duljim - Homepage link - www.prime.net

Što je wPrime?

wPrime uses a recursive call of Newton's method for estimating functions, with f(x)=x2-k, where k is the number we're sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.

Što je tako revolucionarno?

Our aim was to make a perfectly threaded benchmark, such that it would consistantly use 100% of the CPU while in use. This is achieved by using the WMI to detect the CPU count and use exactly that many processing threads to avoid any performance losses due to multiple threads running on any single physical thread. Each thread is designed to do 1/n of the work, where n is the number of threads. For example, if you're calculating 16 roots on 4 CPU's, each CPU will calculate 4 roots. Some might argue that this style of threading is unrealistic in real-time performance, but in fact is quite indicative of performance in several real world tasks such as F@H which allows you to run several instances of the work at any one time.

Kako izgleda to?

Kraj računanja i razultata

Eto, došao novi program za računanje, sličan Super Pi-ju. Ukoliko otkrijete nekakav bug (jer je još to u fazi testiranja) javite čovjeku koji je to radio (imate sve informacije na homepage-u).

Ono što bi ja mogao zamjeriti je da još nisam skužio kak se bore protiv fake-anja rezultata.

S obzirom da ima unutar programa opcija za "submit" rezultata, vjerojatno fora sa fotošopom otpada jer se ne vidi koje se stvari šalju. To je dobro za stranice poput hwbot.org-a, ali kako će forumaši znati dal je netko promjenio sliku di mu je krajnji dobiveni rezultat? Nikako...

Uglavnom, nemojte ovdje postati rezultate, ovdje samo dojmove i probleme koji vas muče. Ako se moderatori slažu, budemo otvorili novi thread.

Do tada, pričekajte malo...
