1) Message boards : News : Thank you! (Message 105679) Posted 24 Mar 2022 by at90systems Post: I was notified by Einstein@home that there are no projects left for my Rpi 4's. Now I see there are no projects left for them here as I started getting "more memory needed" messages recently when attempting to poll updates, and then confirm with the messages I read here. I made sure to get 3 of them, all 4Gb (the 8Gb was not out when I purchased them), mainly for the use for Rosetta and migrated most of them to add Einstein when projects were low here. I ran the Pi's because the electricity is negligible and I felt it was for a good cause. Now C19 is rather under control, I see the needs of science have outlived my equipment and they want me to dedicate my GPU's or larger equipment to the cause, using my electricity that makes an impact. Well sorry, those get reserved for crypto, see those when used for that earn $$$ to pay for their use for that. So no hard feelings, I feel that it was a good run but until needed again my 3 lonely little Pi's are shutdown and being moved to other more fruitful projects. Good luck on future endeavors, email us if you have new projects that can include the ARM group, but until then if it is GPU power you need then I suggest you use the power at hand and grant money and get the super computer that you are so desiring your projects toward, or put it toward lease time. To ignore the smaller parts of the whole is basically a defeat of the goals set forth by the project when it started to begin with, to use any an all resources to band together and solve a common task, not pick and choose which are easier or faster to get the job done. Until next time........

PI units have been working flawlessly now for quite a few days without errors. In regards to why allow Pi units to run, they are more robust than what they were now with the 4Gb and 8Gb versions they can contribute so much to the program. Sure they don't do as much as a computer cluster, but they do contribute. The entire idea behind distributed computing is to allow anything to contribute and take the work load off of a much larger super computer, so in this day and age I say yes more boinc projects need to support them, not only that the space considerations and power consumption used by the units and expense (when compared to purchases not using old hardware though) is great.

4) Message boards : Number crunching : horns named project files causing pgtables out of memory errors in boinc all others run fine (Message 99739) Posted 21 Nov 2020 by at90systems Post: I kind of figured that was the problem to start with thanks for the pointer to the other thread. Surprised to see that since both of my units are 4GB Pi4s. Not to sound crazy but doesn't the need for large amounts of memory to process files like that kind of defeat the purpose of the distributed computing model? I know its tough to find platforms that support the PI equipment (trust me there are only a handful) just strange that there is only this one form (the horns) that requires so much. Seems like an easy fix though, split the files programming down to smaller subsets or limit them to a particular set of boinc users, the boinc registration should be able to supply some type of information as I know if you try to register the Pi with a project that is not supported it tells you that from the get go. It just gets repetitive having to go to the units I have (which are headless for the most part) and keep aborting one single file every day or other day when other subclasses work fine was all I was concerned about. Wondering if using an 8Gb Pi would solve the issue and keeping the 4Gb on machine learning project would fix the issue.
5) Message boards : Number crunching : horns named project files causing pgtables out of memory errors in boinc all others run fine (Message 99732) Posted 21 Nov 2020 by at90systems Post: Have 2 Rpi running Ubuntu. All other project files run fine (named other things) All files I get that are named horns_.....xxxxxx etc. start but eventually cause multiple errors such as pgtables out of memory etc and I am having to abort them to clear the issues. Rebooting the Pi does not solve the issues, happening on both units. It is just the horns named files. Any suggestions or similar problems anyone has noticed with a solution, I hate to keep just aborting a particular strand? TIA
6) Message boards : Number crunching : Rpi Running x64 Linux (Ubuntu) Not Getting Any New Tasks? (Message 97664) Posted 27 Jun 2020 by at90systems Post: Luckily they both received a work payload this afternoon and have been crunching since. Just want to keep them busy. They were purchased for this reason and don't run anything else. I had looked into other projects but it seemed that Einstein and Universe didn't have any projects going on and others did not support my x64 arch linux architecture. However at the moment glad to be running again even if just a few tasks at the time.
7) Message boards : Number crunching : Rpi Running x64 Linux (Ubuntu) Not Getting Any New Tasks? (Message 97638) Posted 26 Jun 2020 by at90systems Post: As of around July 25, both of my Pi4s were running full speed ahead and are now both sitting idle with no new tasks. Yesterday afternoon my primary got 3 items to run but that was it. Is this because they found a protein strain that has worked against Covid and have basically stopped running? Is there some change I missed on this platform maybe that is preventing getting any new tasks? Thanks.
