For search in rank 10, we made a new application. And of course, we implemented the most powerful optimizations. (Due to changes of structure, the need for some is gone). But we hope that this application can be additionally optimized - it's another very interesting problem!

For rank 9 a third-party client was released which utilizes SSE/AVX etc. variants and is significantly faster compared to the original client.
Are you telling me that the current rank 10 app release (which requires run times of up to 4 hrs for some of the tasks I completed - compared to 20 min. for rank 9 tasks on the same machine) already employs the same optimizations incl. an autodetection module to select the appropriate SSE/AVX code?

Michael.


Why would you assume a separate data set will complete in the same time? Might as well say I want my PrimeGrid Seventeen or Bust task to complete in the same time as Sophie Germain.

Daniel and hoarfrost has already said multiple times that much of the optimizations are already in the rank 10 app and to not expect the huge reduction with any AVX/SSE optimization.

Anything you can do would be very much appreciated.

Some of the new units I've returned have taken over 2 hours to complete....


Run time is irrelevant for credit.

Settings in app_config can be re-read when using the BOINC read config file function. BOINCTasks specifies app_config in the button. The event log will show this and any possible errors in the syntax. app_info.xml files require a client restart.

Thanks Daniel for your efforts in getting this out there.

However I seem to have a problem with your new programme, all I get is

<core_client_version>7.4.25</core_client_version>
<![CDATA[
<message>
process exited with code 193 (0xc1, -63)

Exiting...

</stderr_txt>

Which is trashing a heap of work units, I re-downloaded and re-installed the files but this made no difference.
I noticed that the line <platform>xxxx</platform> had been added to the apt_info.xml file so I removed that to see if it made a difference but alas it did not.
So I will re-install your older version and see if all starts working again.

Thanks
Conan


Which app was used? The 955 doesn't have AVX so the SSE app would be required.

Same exe name so these should be a drop in replacement.

Thanks for the great work Daniel.

Were these when tasks became validated or either of the two tasks per unit? The long tail would make me assume it was when tasks were validated and thus push a higher completion count towards the 2nd half of the event.

Not sure it's working on my 1950x with AVX2 app. 34min into my 1st set of tasks and its only 55% done. My older 3770k with only AVX is 19min in and 66%.

It works, but slower than expected. Please try AVX version, it may be faster for you. Recently I read that PEXT instruction from BMI2 set is slow on AMD CPUs, and AVX2 app uses it in most performance-critical part. This can explain why app is so slow on AMD CPU.
https://www.reddit.com/r/Amd/comments/60i6er/ryzen_and_bmi2_strange_behavior_and_high_latencies/

Maybe AVX2 app without BMI instructions would be better here. I will take a look on this.


Yeah, I guess I meant it wasn't working as well as expected. Seeing big numbers put up by others.

Point/CPU Sec went from 0.0454 average to 0.0613 with the AVX app. A good 35% improvement on the 1950x.

Great job and thanks for another optimized app for BOINC!

Just the v7 tasks or the older v6? I have some of both in Linux. All but one v6 task has validated so far.

Thanks. I see it on Free-DC now. Here there was a comment about no stats yet so I wasn't sure if it was ready yet.

https://boincstats.com/en/forum/11/11729,1

I'd rather have project specific badges than the generic Top 1%, Top 5% badges. Most project's don't have those though.
