1) Message boards : News : New study going out to volunteer's machines (Message 68376) Posted 19 Feb 2023 by KAMasud Post: Most people like the Mint(Ubuntu) flavour of Linux. It is thought to be easier for Windows users to use. Popular on Climate. Les, is ever willing to help. As to instructions you will find VB concerned on the VB site. Mint forums and the site have their own instructions. You will need the 32-bit lib files. Instructions are on the Linux-concerned Boinc site. Someone will be along to tell if they are still required for these WUs. I have them from the last batch of WUs, so not too sure.
2) Message boards : News : New study going out to volunteer's machines (Message 68368) Posted 18 Feb 2023 by KAMasud Post: The current batches are linux only. For Windows, running them under WSL (which is what I do), or a virtualbox setup works fine, but that's not for everyone. I do know that CPDN are preparing some more Windows batches though I don't have a timeline for when they will be ready. How about doing what LHC does, send the VB wrapper out so anyone can run your Linux stuff? If you want an older version, download it from the Boinc site. If you wish the current version as we all do, go to the VB site and download it. The flavour of Linux is your choice, go and download it from their site.

The config files that are being spoken about I could find them in FAT but I am lost on NTFS. On both, VB and Windows. Seems like some spoon-feeding is required. Boinc Wiki is silent. Where are the Project Directories? PS. Please don't get annoyed, I am trying. Some background. I am a retired sailor with part-time quarry work so not much hands-on experience with computers.
5) Questions and Answers : Unix/Linux : * Running 32bit CPDN from 64bit Linux - Discussion * (Message 66490) Posted 17 Nov 2022 by KAMasud Post: GPUGrid is slightly different(like CPDN will be with OpenIFS). It is not a single-thread project or even a single-core project. GPUGrid takes over the complete processor. If you have a 64-core processor, it will take up all of them. It graciously leaves one core alone for the OS. As to OpenIFS, I cannot find much as to how it will operate. Will it be multi-threaded, which I have read somewhere it will be? If it is multi-threaded and so is GPUGrid, that will be quite a party going on unless I build a fence around them. Now it starts going beyond my capability and I do not think a six-core machine will be sufficient. https://github.com/CPDN-git/openifs https://confluence.ecmwf.int/display/OIFS/OpenIFS+User+Guide https://confluence.ecmwf.int/display/OIFS/5.4+Download+OpenIFS If you can point out a website where I can find out more, most welcome. Another point was raised somewhere. If GPUGrid is taking over the complete processor and if I run another WU from some other project, the hypothetical question is will there not be interference?

Why do you say that, what exactly do you mean by 'not get along'? Each of those projects will require resources on your machine. If you can't run them concurrently, then adjust your boinc client accordingly and only run a few at a time. There is no technical reason why independent projects can't work on the same machine unless the computer doesn't have the necessary resource (typically RAM). I'm interested to know why you think they don't. I have babies as Richard said. Six core machines with sixteen GB RAM. Each GPUGrid task is taking up a maximum of 98% CPU at peak plus total, machine and task 11.2 GB of RAM. I do not know what OpenIFS will do. I am quite comfortable with Zorin, got it set up but VirtualBox with Zorin and a task from Einstein peaked the machine out. One task of Moo Wrapper can run comfortably with a Python in the cage without VB. Different projects, different requirements. This multi-tasking is giving a pretty high error rate at GPUGrid. My experience, not quoting. Richard, computers came along pretty late for me, somewhere in 1980. Before IBM PC, my experience was with Texas Instruments 8086, and 8088. GWBasic was good enough for loading calculations. I just do not have the know-how to play with these but I can follow instructions if someone has the time to teach. How do I adjust Boinc Client? Any instruction or Cheat Sheet somewhere in Boinc'dom?

Run the following and try to get a task to test things: sudo apt install lib32stdc++6 It is based on Ubuntu. After all this exercise, I do not think GPUGrid, multi-core plus GPU and CPDN with OpenIFS can get along together. @Richard, what conclusions?
8) Questions and Answers : Unix/Linux : * Running 32bit CPDN from 64bit Linux - Discussion * (Message 66422) Posted 15 Nov 2022 by KAMasud Post: If you're going to do a fresh install, try using the GUI software manager to install BOINC. Richard seems to have had success with it. Just to share info, BOINC 7.18.1 (client only, don't have the manager) works on Ubuntu 22.04 on WSL2. I used the software manager on Mint but for some reason failed. However, I was successful on Zorin so far. So, I will stick to Zorin. Now the 32-bit libs.

I tried plus tried to reinstall Boinc Manager and Boinc Client. It reported back, you already have the latest version but I cannot see the GUI. I am going to do a fresh install of Mint and then try again.

Yes, I agree about the aptitude instructions. I first installed that way and it although it worked it was clumsy, and aptitude uses a separate install database which I didn't particularly like. So I dropped it and now just use: sudo apt install boinc-client boinc-manager on Mint which works fine. Note, however you might need to tweak your systemctl file for boinc-client. There is a bug in the current release which prevents vbox apps working correctly (if that's required). I got this on Mint. ~$ sudo apt instal boinc-client boinc-manager [sudo] password for arif: apt Usage: apt command [options] apt help command [options] Commands: add-repository - Add entries to apt sources.list autoclean - Erase old downloaded archive files autopurge - Remove packages with their configuration files and automatically remove all unused packages autoremove - Remove automatically all unused packages build - Build binary or source packages from sources build-dep - Configure build-dependencies for source packages changelog - View a package's changelog check - Verify that there are no broken dependencies clean - Erase downloaded archive files contains - List packages containing a file content - List files contained in a package deb - Install a .deb package depends - Show raw dependency information for a package dist-upgrade - Upgrade the system by removing/installing/upgrading packages download - Download the .deb file for a package edit-sources - Edit /etc/apt/sources.list with your preferred text editor dselect-upgrade - Follow dselect selections full-upgrade - Same as 'dist-upgrade' held - List all held packages help - Show help for a command hold - Hold a package install - Install/upgrade packages list - List packages based on package names policy - Show policy settings purge - Remove packages and their configuration files recommends - List missing recommended packages for a particular package rdepends - Show reverse dependency information for a package reinstall - Download and (possibly) reinstall a currently installed package remove - Remove packages search - Search for a package by name and/or expression show - Display detailed information about a package showhold - Same as 'held' showsrc - Display all the source package records that match the given package name source - Download source archives sources - Same as 'edit-sources' unhold - Unhold a package update - Download lists of new/upgradable packages upgrade - Perform a safe upgrade version - Show the installed version of a package As to Zorin, I tried to test run Moo Wrapper.

14) Questions and Answers : Unix/Linux : * Running 32bit CPDN from 64bit Linux - Discussion * (Message 66312) Posted 9 Nov 2022 by KAMasud Post: The page at Boinc, installing Boinc on Linux. There is something wrong. They have changed the contents of the page recently. The command "apt" has been changed to "aptitude". Linux Mint recognises this command but cannot find the packages boinc-manager boinc-client. However, this command is not recognised by Linux Zorin. So I tried the old command "apt-get" which is still recognised but it still is unable to locate the packages boinc-manager boinc-client. Both Mint and Zorin are the latest. Some help is required.
15) Message boards : Number crunching : Certificate issue. (Message 66157) Posted 30 Sep 2022 by KAMasud Post: I got a WSL not available. Went to check what it was and downloaded it and ended up with Ubuntu. All my VM's on Ubuntu got corrupted. Anyway between the blue screen of death due to my experiment with Windows 11 and WSL all my WU's are in limbo. I have no WU just now. So, can someone show all the WU's against my computers as abandoned and get them re-issued?
16) Message boards : Number crunching : Certificate issue. (Message 66088) Posted 10 Sep 2022 by KAMasud Post: I think you are correct. The last time the VM had this problem, I derated it to minimum RAM and one CPU then let it sit peacefully. One day they all vanished and the problem was solved. PS. Can the spelling of the certificate be corrected?

Each Raspberry Pi 4B has an 8GB RAM flavour available. These Pi4B compute models are cheap and powerful with four cores. Windows for ARM is a no-go, so Linux it will be.
