the quick wu`s are finished it seems, chucking longer taking jobs at me all day, up to 20mins now each

That's a good thing I reckon. I'm sure some of the issues have been caused by the insanely fast turnarounds since the optimized app

The only thing I can think of to try, being as it allows the official app, is to rename the optimised one to exactly the same name as the official one, you will need to change the name to match in the app_info as well.

Doesn't work unfortunately. My guess is it's looking at the file itself and what it does rather than the filename.

Just noticed your location hamesy, i'm just up the road in gridlocked Stafford

Nice to see someone local

Now I'm getting a little confused with all the new optimizations/apps. I'm currently using sesefs latest app but crunch3r has some new ones out:

Which one are you using PDW ? Do you know which is best ? I can't seem to find any more information anywhere. :confused:

PDW · 19 Oct 2015 at 15:20

I'm using Sesef's app but have scaled back for the moment.

I have tried Crunch3r's app on linux and it's obviously much faster than the stock code but is slower than running Sesef's on Windows. I did read a thread on the Denis site about a comparison and IIRC Sesef's is the one to use for Windows.

Will need to get all my boxes changed over to Windows in time for the challenge

I saw that one i think, then a little later on, crunch3r's new revised app appeared with sse4.1 and that's what confused me but from what you're saying I'll stick with sesef's then

Just wanted to make sure I get the max possible for the challenge and soooo close to 100k rac

Congrats Boycie: 200k rac !!

On the short tasks, I found the sse4.1 to be slightly quicker than the lastest sesef's one, about 6-7 seconds, I was doing 3m 15s on crunch3rs and 3m 22s on the other. Not tried it on the longer ones. This was on a 2700K @4.7ghz

That's good to know then, if the difference is so little then I'll definitely leave my apps well alone, finally have 4 machines running the sesef's apps with none of my previous issues. Keeping around 4 to 6hrs of tasks and communicating with the servers every 2 hours (ish).

New sesef AVX2 version released, just about to try it out now.

EDIT: AVX2 version gives me immediate computation errors (3770K)

DOH! Ivybridge doesn't support AVX2

I'll try it on Haswell.

Ooooh, can't wait to hear what you think of it

hanluc · 25 Oct 2015 at 21:19

Haswell [email protected]

sse4.1 = 10 mins per WU average.
AVX2= 9mins 17 secs average.

9.2% increase.

As long as they validate OK, well worth changing.

andy_taximan · 25 Oct 2015 at 22:30

Trying it now

That's decent

Still sitting in the client task list on your pc?

Just looked at my tasks page on denis site; i have 1077 validation pending !

I started a thread on denis forum here Andy: http://denis.usj.es/denisathome/forum_thread.php?id=78#594

I've switched my CPU across from F@H to DENIS. Got it set up and running with the SESEF optimised app running (I think). It's generating 4 tasks and each is taking about 2 hours to complete. Does this seem right? The CPU is i5 4690k at stock. I have set one core in F@H to fold for the GPU reporting there.

The two files are in correct directory (Programdata\BOINC\projects\denis....\

Thanks for any advice.
