Posted 13 May 2024 by ahorek's team Post: The ETA is inaccurate because BOINC hasn't benchmarked the new app yet. It'll settle after finishing a few WUs. Anyway, I see nairb's tasks were successful, which is a good sign. Thank you both! |

Posted 13 May 2024 by ahorek's team Post: the new version has all optimizations in a single application and chooses between them dynamically based on your hardware capabilities. you can check which optimizations were used in the stderr log BOINC client version 8.0.1 Application: ../../projects/asteroidsathome.net_boinc/period_search_10220_x86_64-pc-linux-gnu Version: 102.20.1.1 CPU: AMD Ryzen 9 7950X 16-Core Processor RAM: 15.35 GB Using AVX512 SIMD optimizations. |

Posted 13 May 2024 by ahorek's team Post: thanks, it turns out I made a mistake while building the app. Here's an updated version https://fileport.io/qCXSSnT4xCJQ could you please check? |

Posted 13 May 2024 by ahorek's team Post: Thanks for your patience. Hopefully, we will be able to release a patched version this week. |

Posted 13 May 2024 by ahorek's team Post: hmmm, it should work. Alternatively, you can force SSE3 optimizations with app_config.xml
<app_config>
<app_version>
<app_name>period_search</app_name>
<plan_class></plan_class>
<cmdline>--optimization 3</cmdline>
</app_version>
</app_config>
however, expect a slightly worse performance compared to the AVX version. |

Posted 12 May 2024 by ahorek's team Post: you can test it with the sample work unit "period_search_in". For https://boinc.berkeley.edu/wiki/Anonymous_platform put the binary in the project's folder, create app_info.xml, and restart the boinc client. /var/lib/boinc/projects/asteroidsathome.net_boinc/app_info.xml
<app_info>
<app>
<name>period_search</name>
</app>
<file_info>
<name>period_search_BOINC_linux_10220_x64_universal_linux_Release</name>
<executable/>
</file_info>
<app_version>
<app_name>period_search</app_name>
<version_num>10220</version_num>
<avg_ncpus>1.000000</avg_ncpus>

Posted 12 May 2024 by ahorek's team Post: it's indeed a bug in the AVX implementation, that mostly affects hosts with legacy Intel CPUs like Sandy Bridge on Linux. we already have a fix, but releasing it would take some time (about a week) could you test this version? it would be helpful if you could double-check it works as expected on these systems. You can also run regular tasks using the anonymous platform with it. https://fileport.io/wWq7w3weQMBq thanks and sorry for the inconvenience! |

Posted 11 May 2024 by ahorek's team Post: the new arm64 native application now utilizes asimd instruction set, so it should be more close and likely faster than the emulated x86_64 version. |

Posted 11 May 2024 by ahorek's team Post: version 102.20 has been released. It includes new hand-written optimizations for asimd instruction set, that should give a substantial performance boost on supported 64-bit ARM v8 processors like Apple Mx and RPis. |

Posted 23 Apr 2024 by ahorek's team Post: we have decided to detect available features by the app instead of having multiple apps and relying on what the boinc client reports. Once (hopefully soon) we release a new version, this boinc feature won't be relevant to us anymore. btw Primegrid has used the same technique for a long time. http://www.primegrid.com/forum_thread.php?id=10534 until then, there's still an option to run optimized versions on Windows via anonymous platform (if your hardware supports it). Compared to FMA it's up to 20% faster on Intel and slightly faster on AMD (Zen 4). There are rumors that Zen 5 will improve the AVX512 performance, which might be interesting. |

Posted 27 Mar 2024 by ahorek's team Post: I've tested the alpha 8.0 version and have no issues getting new tasks. Could you double-check if CPU work is enabled in your account manager preferences? Also, the client may not request new work, if your host is busy running other projects. |

Posted 27 Mar 2024 by ahorek's team Post: you can download avx512 apps from https://asteroidsathome.net/boinc/download/period_search_10215_windows_x86_64__avx512_win10.exe https://asteroidsathome.net/boinc/download/period_search_10215_x86_64-pc-linux-gnu__avx512_linux ensure your CPU has avx512 support (like AMD Zen 4, Intel Ice Lake, Intel Sapphire Rapids etc.). |

Posted 19 Mar 2024 by ahorek's team Post: Keith's issue was unrelated to the android's app. The new android app still hasn't been released, so the "Number of lc points is greater than POINTS_MAX = 1000" problem is still present. The code is ready, we just need to build it and upload a new release to the server. Unfortunately, I don't have access to the server, so it has to wait for Georgi & Radim once they have time to do it. |

Posted 18 Mar 2024 by ahorek's team Post: Cause I always get SSE3 app and never get AVX/FMA ones. I think my CPU 5700X support these. you're right, the fact that BOINC is stuck with SSE3 and never tries new, more optimized apps (on some hosts) is a bug either with the server configuration or the BOINC server code. however, there are more related issues with this approach. BOINC doesn't reliably report all necessary features on all platforms. Windows is the most important one, but the same issue is on BSD and Macs all of them have their specific way of detecting features, so we have decided to develop a new app that selects the best implementation at runtime instead of relying on what the BOINC client says. It's already in the testing phase. if you have this issue and don't want to wait for the next release, using an anonymous platform as Keith suggested is a workaround to get the best performance. I admit it's inconvenient for users who aren't familiar with it, but please be patient, we're working on a solution :) |

Posted 9 Mar 2024 by ahorek's team Post: I have some news from admins, there was a DOS attack from China's network on the website 1000 to 8000 connections at a time. They took some preventive measures. It's hard to say if there's any connection with the Challenge though, it could be just a coincidence. |

Posted 9 Mar 2024 by ahorek's team Post: sorry for the trouble, the server should easily handle +200 (/4500) more users during the challenge. Perhaps the webserver ran out of free connections or more likely someone's deliberately hitting it too hard (by downloading an insane amount of work, crawling the website etc.). Unfortunately, only the university has access to the firewall & logs and it may take some time for them to investigate what exactly has happened especially during a weekend. They're aware of the issue, but I don't know more yet. |

Posted 7 Feb 2024 by ahorek's team Post: sometimes the queue gets dry and it takes a day until admins fill it up again. you can monitor available work here https://grafana.kiska.pw/d/boinc/boinc?orgId=1&var-project=Asteroids@Home&from=now-30d&to=now |
