D41.xx Observation Thread

Completed 2 WUs (r_1362) in about 2660 sec using D41 on AMD X2, no erros so far
Will put D40 app to compare speed with D41; got 3 more WUs to go...

Another 2 WUs with previous

Another 2 WUs with previous app version D40 took 3470 sec each.
D41 looks like 0.77 time-to-complete compating D40.
I would call that a way "to improve the calculation performance" :-)

Good job, akosf.

Hope to see results from other users/machines soon...

Loaded an Athlon 3000+ and so

Loaded an Athlon 3000+ and so far it looks like D41.12 will be a rocket! Will load the dual cores as well. Akosf, fantastic!
>First result indicates ~12% speedup over S40.12!! No validation yet....Cheers, Rog.
(I hope they raise the MDQ above 32/day soon!!)
>First result on a 1.8MHz Duron indicates ~15% speed increase over S40.12...:)

Well, on my Athlon 64 3000+

Well, on my Athlon 64 3000+ it looks like that D41.12 is about 15-20% faster then S40.12(!) Awesome! Thanks akosf!

Another WU with D41 finish so

Another WU with D41 finish so my previous evaulation was not a measurement error - you can expert about +23% boots over D40 on X2 machine.

Yeah, it's a rocket...I've even lost comparation to oficial tortoise, D41 is a real cruncher, not a crawler :-)

EDIT: Based on first WUs completed and comparing it with other resultsIDs, D41 is almost 3 x faster over Linux 4.55 app (AMD X2).

Another good news - first WU with D41 got validated.

Bad news - speed of 45 minutes per 'long' WU gives exactly 32WU/day/core which makes my machine to meet daily quota and get dry on Einstein.

First result: 1432 cycles ("long" WU) - 43 minutes! Last instaled opti version, S40.12 - 51 minutes. Great job! I am waiting for validation. Bad news - I reached the daily quota, :(((.

it's time to try the "fake"

it's time to try the "fake" CPU feature from BoincStudio, but consider that BS is in an early beta state.
