Problem long crunch time
(1/1)
Skywalker66_Bln:
i have a problem on one of my computers,
GPU crunching time is normal 0:20-1:30h, in the last days i have a few WUs that run 3:30. that is not the problem. Because all wu-times of uncrunched were crash to high times.
WU http://setiathome.berkeley.edu/workunit.php?wuid=594291916 as example
WU true angle range is : 0.294035
it is no Vlar
cpu usage by crunching is by low 0,0015-0,0081%
boinc 6.10.43 / Cuda 2.3
GPU are calculateted with 131gflops peak /5,6 x0,5 = 11,696 gflops ( on my other Computers run this calculation perfectly)

Have anyone a good idea ? or a better calculation ?
Thanks for help
Skywalker66_Bln:
i am back to the basics
cpu <p_flops> x0
gpu Gflops peak /5,6 (to east. gflops) then *0,2
post like http://setiathome.berkeley.edu/forum_thread.php?id=54801 make me crazy
it is a pity which has struck nobody here a little bit and give a comment in addition hand in has. Or only of all malicious pleasure?
I thought I am with the best ones of the best who also help each other...

I wouldn't worry about it, the Workunit AR is below a normal AR, but above the value for being a VLAR Wu, so wouldn't get aborted by the app,
as it happens, my 9800GTX+ has done some of a similiar AR, and took twice as long as a normal AR Wu:

I think that
gpu Gflops peak /5,6 (to east. gflops) then x0,5 (x0,09) is to high
i work on a simple optimisation way that can newbee´s or non englisch speaking people understand
at the moment, i am by a factor from x0,43 (x0,077). it shows as a pointlandet place. i am interested to show on my other Computers
