At the moment its running NVidia OpenCL app at around 52-53 seconds settings @1115/300. Which is a good time for a WU written to (principly) run on NVidia hardware.



Try to run 2 wus in parallel, you should get few extra seconds :). Now I have about 43 sec/wu @1200/685

Some fun with 7970

best clock without voltage change


best clock


I think OC over 1200 Mhz is worthless. You can get 1200 Mhz without voltage change/with small change and get extra 3 sec. For 1300 Mhz I had to set almost 1,3V to speed up only 3 more seconds :(.

Post:
Hello MW@Home,

I took over the BOINC server this past weekend (Saturday is when these "small" WUS should have started showing up).

For the prior 2-3 weeks Travis had been running convergence tests on 5 degree wide stripes-- I am however working on 2.5 degree wide stripes which translates to half as many nu steps and thus half as large WUs. These WUs should be running just as fast as they usually ran before I introduced the 5 degree stripe size about 2 months ago-- is this so?

I can put some more 5 degree tests up later today when I get a chance.

Thanks for your patience,
John Vickers


I think mix with 2,5 degree and 5 degree wu's will be the best.

I do not think we can from our computers. As Travis posted here about the only method to verify that good results are being churned out.



And how would one do that? There were no sample inputs given with the code. Just the same link and app that others downloaded from arizmoon.com


Yes there are, if you go to http://milkyway.cs.rpi.edu/milkyway/download/code_release/
all of these have sample input files.



Ok, I downloaded the Milkyway release .7 (I am assuming that I was supposed to download the latest one?) Now what do I do with them? Sorry--I dont mean to be a pain...

Thanks





You should be able to put the milkyway executable and the other executable in the same directory with the sample inputs and run them. This would be (from where you uncompressed the files) ./milkyway/bin/test_files/



Ok, copied them into the same folder and ran them, now what am I looking at?




in this folder you'll find file "out", last line of this file is your result.

sesef, could you also check your faster app you are using please?


which applications do you mean?

sorry i thought in your team there where also optimized apps used made by some of your teammade.
i had the user mindc in my mind.
nevermind if im wrong.


Ahh you mean about this app, it returns correct results (same as oryginal app -3.046272445362277)

Which of the faster apps gives out garbage results?
SSE 2 or SSE3? Or all? *scratches head*


MW-update18

SSE3:

My CPU dont have SSSE3 and SSE4.1 instructions, so I cant test it.
