1) Message boards : News : Universe@Home is ending... :( (Message 6509) Posted 11 Nov 2024 by Keith Myers Post: Thanks for the update Kris. Happy to hear what the final resolution is. It was a good run and am happy I was able to participate for such a long time. Universe@home will be missed. Best wishes to you in your future endeavors. Cheers.
2) Message boards : News : Universe@Home future (Message 6485) Posted 18 Jul 2024 by Keith Myers Post: Well, I'm very pleased to hear that the project will go on. Super! That is incorrect. Project continuation is still undecided. What I wish is some information about the timeline for the decision to continue or shut down. Somebody needs to get CAMK to provide some insight to their decision process and when will that process happen.
3) Message boards : Number crunching : ARM cpu crunching (Message 6420) Posted 4 Feb 2024 by Keith Myers Post: Instead of 'contrib' and 'non-free' you can better use 'restricted' and 'universe' in case of L4T...I have the 4GB model working now at SiDock, but it was quite a struggle to get all 32-bit libraries. BTW: I received Universe WUs for the 4GB model over the last three days (1, 2 and 3 February 2024). Not many but it might be a sign that the 'dry spell' will not last forever. Tried with restricted and universe. Same difference. No luck. Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'https://repo.download.nvidia.com/jetson/common r32.7 InRelease' doesn't support architecture 'armhf' W: Skipping acquire of configured file 'restricted/binary-arm64/Packages' as repository 'https://repo.download.nvidia.com/jetson/common r32.7 InRelease' doesn't have the component 'restricted' (component misspelt in sources.list?) W: Skipping acquire of configured file 'universe/binary-armhf/Packages' as repository 'https://repo.download.nvidia.com/jetson/common r32.7 InRelease' doesn't have the component 'universe' (component misspelt in sources.list?)
4) Message boards : Number crunching : ARM cpu crunching (Message 6419) Posted 4 Feb 2024 by Keith Myers Post: First things first! First step 1: sudo dpkg --add-architecture armfh Then step 2: sudo apt update --fix-missing only thereafter can you do Step 3: sudo apt install libc6:armhf libstdc++6:armhf zlib1g:armhf libfuse2:armhf libgomp1:armhf libboinc7:armhf I myself am presently re-doing these steps as my fallback project -SiDock@Home- has stiffer requirements and my 4GB Nano seems to be missing libgomp1:armhf. My 2GB model can't even run SiDock: its 18.04 L4T has glibc 2.27, too low for SiDock /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.28' not found (required by ../../projects/www.sidock.si_sidock/cmdock-s_wrapper_2.02_arm-unknown-linux-gnueabihf) I followed your post https://universeathome.pl/universe/forum_thread.php?id=680&postid=6394 verbatim Adding the architecture right off the bat produces the errors. That is before I tried to add the armhf libraries which produce further errors.

6) Message boards : Number crunching : ARM cpu crunching (Message 6400) Posted 27 Jan 2024 by Keith Myers Post: Your link points to a host with 0.10 RAC. You are surely confused about ARM performance
7) Message boards : Number crunching : ARM cpu crunching (Message 6396) Posted 26 Jan 2024 by Keith Myers Post: Still no luck with your suggestions. Endless list of errors saying "skipping acquire of of configured file" "inrelease doesn't have the component 'contrib' and component 'non-free' check spelling InRelease' doesn't support architecture 'armhf'
8) Message boards : Number crunching : ARM cpu crunching (Message 6392) Posted 25 Jan 2024 by Keith Myers Post: I would have liked to get my Jetson SoC's running on Universe but alas there are no 32 bit libraries available in the Nvidia L4T distros. I could change them over to a normal Linux distro like Ubuntu but I would lose the standard Nvidia CUDA development installation that allows me to use the Nvidia gpus at Einstein where they are quite productive. Both my Jetsons crunch Universe and run L4T (the 4GB model upgraded to 20.04.6 LTS with Glibc 2.31). I got some warnings installing 32-bit libraries, but it is workable. The 2GB model even has a both OpenCL and CUDA capable GPU, but still runs on 18.04.6 LTS and has Glibc 2.27 Where did you find the 32bit libraries in L4T? I have a Nano 4GB original and a 4GB TX2-NX both running the L4T based on 18.04.6 LTS and I just get messages that any 32bit library is unavailable in the distro.
9) Message boards : Number crunching : ARM cpu crunching (Message 6391) Posted 25 Jan 2024 by Keith Myers Post: Any idea why this RasPi does not get any WU? Do you have the 32 bit libraries installed?
10) Message boards : Number crunching : ARM cpu crunching (Message 6322) Posted 21 Dec 2023 by Keith Myers Post: As long as you aren't thermal or TDP throttling running four tasks.
11) Message boards : Number crunching : Server Thread (Message 6309) Posted 18 Dec 2023 by Keith Myers Post: None of the back-end processes are running like the work generators or validators.
12) Questions and Answers : Unix/Linux : can't install BOINC on Ubuntu (Message 6267) Posted 20 Sep 2023 by Keith Myers Post: Also very easy to resolve for any Debian based distro. Just add yourself to the BOINC group to get permission to launch the Boinc Manager. sudo usermod -aG boinc $USER Then just logoff the Desktop and login again or just reboot. To see if you are now in the boinc group, just issue: groups in the Terminal. See here. https://boinc.berkeley.edu/wiki/Installing_BOINC_on_Debian_or_Ubuntu or https://boinc.berkeley.edu/gui_rpc_passwd.php After adding yourself to boinc group you should have no issues launching Boinc Manager from the Desktop or Applications.
13) Message boards : Number crunching : Gpu App? (Message 6263) Posted 2 Sep 2023 by Keith Myers Post: What AMD GPU's work? None. This is a cpu only project.
14) Message boards : Number crunching : 9 hours run time? (Message 6251) Posted 26 Jul 2023 by Keith Myers Post: On my 7950X under Linux, my Universe tasks complete within the 15-50 minute window. 9 hours is a stuck task.
15) Message boards : Number crunching : Gpu App? (Message 6221) Posted 23 Jun 2023 by Keith Myers Post: But then you mention the threadripper. Mine is a Ryzen 9 3900XT, not 7900. Can you link to a threadripper so I can have a look? I find it hard to believe they aren't way faster than mine. Sorry, forgot which Ryzen you have. The #2 Top Participant is a TR 3970X Threadripper. https://asteroidsathome.net/boinc/results.php?hostid=708920 Similar core count as your 3900XT - 12 cores/24 threads. He is running even faster than yours. 1900 seconds per task. NOT running hyperthreaded at 32 threads. Reported 41 tasks in the same scheduler connection. He is keeping the clock rate up at boost obviously by not running hyperthreaded. https://www.cpubenchmark.net/cpu.php?cpu=AMD+Ryzen+Threadripper+3970X&id=3623 3.7Ghz base clock. But more likely closer to the 4.5Ghz boost clock based on the runtimes. This host proves your point. But I assert this host in an outlier from the general population. The most common and numerous processor is some Intel cpu, probably trending toward a Xeon with their lower clock speeds and longer runtimes.
16) Message boards : Number crunching : Gpu App? (Message 6217) Posted 23 Jun 2023 by Keith Myers Post: The only reason why Einstein is at the top of the chart of my projects is because the Gamma-Ray gpu tasks award a very high credit award. And they run quickly with my anonymous application. And I've been doing Einstein the longest of all my existing current projects. I looked at other fast hosts on the top participants page similar to your Ryzen 9 7900XT and the Threadripper hosts have similar clock speeds but don't achieve the same runtimes as your lighter loaded 32 thread cpu. Your host is not typical of the general populace of hosts. I'm just saying that for most hosts, the cpu tasks take a lot longer to run and even with more tasks running at the same time, they don't achieve the same RAC as my hosts using a gpu. Also, I don't run Asteroids all by itself. It shares the gpus along with all my other gpu projects. Only 20% resource share. If I was using 100% resource share at Asteroids and exclusively running that project all by itself, like you do with a cpu only project, my RAC would be much, much higher. I only run one Asteroid task for every other 5 gpu tasks from Einstein, WCG and Numberfields.
17) Message boards : Number crunching : Gpu App? (Message 6213) Posted 22 Jun 2023 by Keith Myers Post: Yes, I am running 0.5 gpu_usage on all my gpu projects. So divide that 220 seconds in half. I looked at the top participants list and most of the first page have cpu runtimes in the one hour to two hour values. So nowhere near your 2750 second runtimes.
18) Message boards : Number crunching : Gpu App? (Message 6210) Posted 22 Jun 2023 by Keith Myers Post: Unless you are running an absolutely ancient card from the Kepler or Maxwell families, you will never be issued a CUDA55 application. Most people will be issued the CUDA102 or CUDA118 applications which are much faster and require much newer drivers. Those CUDA applications are much faster than running a task on the cpu. Productivity will be much greater also even if running cpu tasks on all cores.
19) Message boards : Number crunching : Gpu App? (Message 6208) Posted 21 Jun 2023 by Keith Myers Post: Yes. CUDA is a Nvidia compute language. Only runs on Nvidia cards. Much more advanced and capable compared to OpenCL. But there are no gpu apps here.
