1) Message boards : News : Future of the RakeSearch project (Message 1029) Posted 6 Jun 2019 by mmonnin Post: 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.

Some of the new units I've returned have taken over 2 hours to complete.... Run time is irrelevant for credit.

5) Message boards : News : Future of the RakeSearch project (Message 977) Posted 29 May 2019 by mmonnin Post: Over 300 v10 tasks completed w/o error. There is no more work atm for the new app.
6) Questions and Answers : Unix/Linux : Project not reading app_config file (Message 963) Posted 23 May 2019 by mmonnin Post: 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.
7) Questions and Answers : Unix/Linux : Segfault on Linux (Message 813) Posted 11 Mar 2019 by mmonnin Post: Was that Ryzen purchased early? Early Zen CPUs segfault and could be RMA'd.
8) Message boards : Number crunching : Optimized RakeSearch app for rank 9 (computations finished) (Message 729) Posted 5 Feb 2019 by mmonnin Post: 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) </message> <stderr_txt> SIGILL: illegal instruction Stack trace (10 frames): [0x411740] [0x4f0b10] [0x40c282] [0x409d6c] [0x40cdc4] [0x4063dd] [0x404f5c] [0x4f21a4] [0x4f2421] [0x4058b6] 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.

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.

12) Message boards : News : The last part of November and the first part of December results! (Message 200) Posted 5 Dec 2017 by mmonnin Post: What will be the other badge thresholds be set at? Link above shows there are more point levels to come although the weasel is missing from that link.

14) Message boards : Number crunching : Optimized RakeSearch app for rank 9 (computations finished) (Message 188) Posted 2 Dec 2017 by mmonnin Post: 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!

16) Message boards : News : Request to reset the project (Message 107) Posted 13 Oct 2017 by mmonnin Post: The last several v6 tasks spent like a day at 100% so I aborted them.
17) Message boards : News : Request to reset the project (Message 94) Posted 11 Oct 2017 by mmonnin Post: Just the v7 tasks or the older v6? I have some of both in Linux. All but one v6 task has validated so far.
18) Questions and Answers : Web site : Stats (Message 33) Posted 13 Sep 2017 by mmonnin Post: 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.
19) Questions and Answers : Web site : Stats (Message 27) Posted 12 Sep 2017 by mmonnin Post: Is there a stats export for sites like Free-DC and BOINC Stats to pick up?
20) Questions and Answers : Web site : URL Address? (Message 17) Posted 9 Sep 2017 by mmonnin Post: Is there going to be a .com address or just an IP?
