1) Message boards : Science : What exactly is this project about? (Message 2178) Posted 3 Sep 2023 by Dirk Broer Post: Thank you for your comments. We have added it to the main page of the project: http://denis.usj.es/index.html Could you do it again?
2) Message boards : Number crunching : ARM/ARM64 (Raspberry Pi) support (Message 2165) Posted 4 Aug 2023 by Dirk Broer Post: I have 16 Raspberry Pi's version 5.10.103-v7l+ which are 32 bit and would like to try them on Dennis@Home. I currently get the message:" 5994 DENIS@home 23/06/2023 2:34:42 AM Message from server: This project doesn't support computers of type arm-unknown-linux-gnueabihf Thanks You might want to upgrade to kernel 6.1, even when running a 32-bit OS: https://www.raspberrypi.com/software/operating-systems/
3) Message boards : Number crunching : ARM/ARM64 (Raspberry Pi) support (Message 2164) Posted 4 Aug 2023 by Dirk Broer Post: upgrade them to 64bit raspi os! Provided that they are equipped with a 64-bit CPU and have enough RAM Raspberry Pi 4, 400, CM4: Cortex-A72, good; Raspberry Pi 3B, 3B+, CM3, CM3+: Cortex-A53, less good; Raspberry Pi 3A+ and Zero 2: Cortex-A53, but perhaps not enough RAM (512MB for four cores) to run DENIS. N.B.: The Raspberry Pi 2 Model B v1.2 also has a Cortex-A53. Lesser Raspberries (with as best example the Raspberry Pi 2 Model B v1.1 have a 32-bit CPU (Cortex-A7 for the Raspberry Pi 2 Model B v1.1, others (Pi Zero, original Model B, B+) have an ARM11 so you can't run a 64-bit OS on them.
4) Message boards : Number crunching : Myocyte v0.15 Beta (Message 1802) Posted 30 Jul 2022 by Dirk Broer Post: Aborted mine (Beta of DENIS-myocyte v0.15 windows_x86_64) after they had come to a standstill (estimated running times up to 97 days!)

6) Message boards : Number crunching : Stat's Export (Message 1593) Posted 30 Mar 2022 by Dirk Broer Post: https://boinc.berkeley.edu/trac/wiki/XmlStats: tables.xml This gives the total number of teams, users, and hosts. It also includes the UNIX time when the files were last generated, a list of the project's applications, and the list of badges defined by the project. For example: <tables> <update_time>1046220857</update_time> [ <credit_by_app/> ] <nusers>127</nusers> <nteams>14</nteams> <nhosts>681</nhosts> <total_credit>1234.234</total_credit> <applications> <application> <name>setiathome</name> <results_unsent>100</results_unsent> <results_in_progress>1000</results_in_progress> <results_over>10000</results_over> </application> ... </applications> <badges> <badge> <id>10</id> <name>user_pct_2</name> <title>Top 25% in average credit</name> <image_url>img/pct_25.png</image_url> </badge> ... </badges> </tables> host.gz List of hosts team.gz List of teams user.gz List of users badge_user.gz list of user badge assignments badge_team.gz list of team badge assignments If the <credit_by_app/> flag is present in tables.xml, there will also be user_work.gz user credit, broken down by app team_work.gz team credit, broken down by app The format of the various XML elements in the output files is as follows. Notes: <cpid> ('cross-project identifier') is a unique identifier across multiple projects. Accounts with the same email address on different projects will have the same cross-project identifier (as long as at least one computer is attached to both accounts). All 'expavg_credit' values were computed at some point in the past (given by 'expavg_time'). To compute their current values, they must be scaled according to the RAC decay formula. Text fields may contain XML entities. If you aren't using a real XML parser, you need to decode the entities yourself.

8) Message boards : News : Re-starting the project! (Message 1363) Posted 22 Mar 2018 by Dirk Broer Post: Thank you for fixing it! UPLOADS are working again No, they are not...it is like sucking peanut butter through a straw
9) Message boards : Number crunching : Account deleted (Message 1264) Posted 28 Jun 2017 by Dirk Broer Post: Situation is now restored up till 17-06-2017 - I miss just one day's effort, 584 credits.
10) Message boards : News : Problems in the server (Message 1241) Posted 23 Jun 2017 by Dirk Broer Post: Dear volunteers, These days we have been suffering problems in the database due to an update. Many information was corrupted in the process. We have recovery a backup copy but it is a bit old. We are working to get everything working well as soon as possible. Please, be patient and thank you in advance. Best regards. Next time you update, do a backup first... In the meantime: Good luck with the restore, I hope the project hasn't lost data.
11) Message boards : News : Problems in the server (Message 1240) Posted 22 Jun 2017 by Dirk Broer Post: There are people who have lost more than 1,000,000 credits, look it up in BOINCStats and/or FreeDC...
12) Message boards : Number crunching : ARM application? (Message 653) Posted 7 Nov 2015 by Dirk Broer Post: Can any of the optimizing compilers try for a ARM application? To be used with either Linux (e.g. Raspbian) and/or Android? Don't bother with the original Raspberry Pi (ARMv6), but focus on later designs using ARMv7 (32-bit) and ARMv8 (64-bit).
13) Message boards : Number crunching : Android app ? (Message 582) Posted 25 Oct 2015 by Dirk Broer Post: Any news on Android?? I am going to add an octa-core (Allwinner A80) ARM box to my farm which should be able to crunch your WUs with ease.
