Can we have a 64-bit ARMv8 application? Deprecated: Creation of dynamic property BoincUser::$prefs is deprecated in /var/boincadm/prj/html/inc/forum_db.inc on line 164 (Message 4756) Posted 23 Jul 2022 by Dirk Broer Post: Actually we could! I suppose you mean aarch64-unknown-linux-gnu for 64-bit ARM Linux as opposed to arm-unknown-linux-gnueabihf for 32-bit ARM Linux For even more BOINC platform strings: see https://boinc.berkeley.edu/trac/wiki/BoincPlatforms. |

Can we have a 64-bit ARMv8 application?
(Message 4752)
Posted 15 Jul 2022 by Dirk Broer Post: The present 32-bit ARMv7 application needs a lot of memory, so much that a Nvidia Jetson Nano with 2GB of RAM can't complete the tasks when doing four at a time -a 4GB model can barely finish them. A 4GB Odroid-N2+ that has six cores can't do six at a time, but has no problem doing two. As a 64-bit ARMv8 application could address much more memory it might speed up the calculations (with WEP-M+2 a 64-bit app halved the calculation time under Linux/ARM, under Android it was even brought back to a quarter). |

FreeDC: T.Brada Experimental Grid Prime Tuples 214,223 -76,988 According to my account page: Prime Tuples credit 306,818 total, 1,332.94 average (4678 tasks) BoincStats reports 625,683.89 total credit (they have a fail-over for negative credit) |

ARM SPT RAM Usage
(Message 4629)
Posted 1 Jul 2021 by Dirk Broer Post: I think I can state that the SPT app needs at least 1GB RAM per core to run without problems. I suspended three tasks on the Jetson Nano 2GB, because the progress after 23 hours was minimal. The Odroid-N2+ has 4GB for six cores and also falls below the limit. It needs to be nursed back to running state and have at least two task suspended. It is a pity my 8GB Raspberry Pi 4 doesn't get tasks, even though it has the needed alternate platform added to the cc_config.xml |

ARM SPT RAM Usage
(Message 4628)
Posted 1 Jul 2021 by Dirk Broer Post: Nvidia Jetson Nano 2GB: low CPU usage on all four Cortex-A57 cores (5-10%), takes forever (four task, running 16 to 14 hours now, wanting one to four more days) Nvidia Jetson Nano 4GB: high CPU usage on all four Cortex-A57 cores (99.0-99.3%), takes on average 15,000 seconds per WU Odroid-N2+ 4GB: The four Cortex-A73 cores each take 74% CPU, the two A53 cores take 86-87%, big variance in task completion time (498 to 19,000 secs.) These three systems all make use of ZRAM |

Sudden credit loss, 2021-04-02
(Message 4597)
Posted 2 Apr 2021 by Dirk Broer Post: Today I was surprised with a credit score of -76,988. The loss was all with Prime Tuples, which went to 214,223 from yesterday's 291,211. All credit scored between 2021-02-26 and 2021-03-15 is gone. |

Badges
(Message 4317)
Posted 23 Oct 2020 by Dirk Broer Post: This project has three subprojects. Badges are handed out for the total number of credits, for the RAC (the (in)famous generic temporary badges that are the same for all projects) and for just one of the subprojects, Prime Tuples. Why are there no badges for PADLS-Total? I don't think anybody has enough credits for Lua-Experimental to warrant a badge for that subproject, but still... |

Zero Credit
(Message 4269)
Posted 25 Aug 2020 by Dirk Broer Post: Fixed the issue in FUH (how it got back in??). The standard case, I'm afraid: You have your original source code, which goes into production. Problems arise, you make a fix on the production code. You develop a new version, from the original source code The new version has the same issue as the old had... millions went before you.... |

Posted 12 Jul 2020 by Dirk Broer Post: Since the change in FUH, the cleaner is not working. It must be changed to delete the input and output blobs too, but only for TOT5 app! Anything that we volunteers can do? All downloads for TOT5 fail. WU download error: couldn't get input files: <file_xfer_error> <file_name>tot5_51c_Sf2A9sjBgHiTnmrgfQBzSkcRh.in</file_name> <error_code>-224 (permanent HTTP error)</error_code> <error_message>permanent HTTP error</error_message> </file_xfer_error> |

Database Crash and Recovery
(Message 3992)
Posted 4 Feb 2020 by Dirk Broer Post: I think that what I done, is the most I can do. The lost or aborted results and credits are lost. I've got the xml files prior to the crash if you'd like to use them to restore credits ?? It would be wise to ask Bok for the content of what he can supply before stating 'all is lost' |

Posted 31 Jan 2020 by Dirk Broer Post: Dear Bok. I do not think I need the xml files. Most of the credit has been granted for recovered work. And the rest would be just too much hassle to import. This is the result of the crash...for some devastating |
