If it were possible to trade points for bathroom tissue, I'd be upset. That means my totals are increasing slower than before. On a more serious note, the version of BOINC from backports is working really well and there have been no errors since installing it. Working backwards in time I was amazed to discover the currently running Rosetta machine would count as number 499 on the list of top supercomputers as recently as November 2018 and first place by a wide margin November 2007. How many more Raspberry Pi computers would that be equivalent to? That means only 262 more TFLOPS are needed to reach today's supercomputer levels of performance. Surprised, I turned to the list of top 500 supercomputers in the world and discovered the least on that list was an Inspur TS10000 in China with a performance of 1142 TFLOPS. Indicates the Rosetta project is currently running at 880 TFLOPS, due in part to the combined efforts of too many Raspberry Pi computers along with many others. That may, in fact, be fortunate as much of it was indecipherable barking anyway. Since not all the characters encoded by PETSCII have corresponding Unicode representations, I can't reproduce the astonishing contents of the ensuing chat session here. I sent an invitation to have a socially distanced Zoom conference about Rosetta to the dog developer who whined even Jitsi was incompatible with the PET and suggested the Punter protocol Why wasn't this added to Raspbian long ago? While the most well-known computation of this type is weather forecasting, any type of forecasting that characterizes model error using a noise process could work.ĭoes anyone have a good model for the epidemic? It would be interesting to see one that tries to factor in the rate of genetic mutation for the virus based on current number of infected hosts and use the resulting natural selection to update R0 for how contagious the prevalent strain is over time.īack on topic, I'm quite impressed with how well the 64-bit nspawn environment on the Pi 3B+ is working. For example, one could create some large ensembles to obtain accurate statistics related to the evolution of non-linear stochastic partial differential equations. It's temping to try writing code that runs under BOINC. So far it's prompted me to learn about the 64-bit nspawn environment in Raspbian and how to run a BOINC client. The only "solutionW is to reboot and try to hit the magic window again.Covid is bad for humanity, but good for the planet If that has happened and the throbbing has stopped and the BOINC Manager has not opened, then it will almost never open after that. When it fails, you can see the sidebar icon throbbing for about 20 seconds after the click. If I click at that time (and ONLY at that time), then the BOINC Manager usually opens and runs normally. The first group uses standard icons, and then there is a second group of thumbnail-image-based icons. It's just after the second group of desktop icons have been displayed. There is a point during the startup when I have a pretty good chance of getting the BOINC Manager to open. Not a fix, but on my most troubled Ubuntu machine, I do have a poor workaround. At this point I'm pretty sure that it's basically a memory problem, with not enough memory available for the BOINC Manager to run. World Community Grid & GPUGrid & been seeing the same thing, and it's been getting worse with later releases of Ubuntu. I can't function for long in terminal-only mode - I've assembled this computer for my relatives, and they expect a GUI so they can see their contributions to science. Powered off the PC and moved it on a shelf to prepare for a headless setup. Reinstalled ONLY Graphics Drivers+Gnome tweaks, VLC Player, and BOINC. Whereas I'm manually clicking on the power controls in the upper right hand corner and selecting Power Off (presumably that's what we're all supposed to do).Īdvise was either find "a lock file somewhere" or else wipe the machine and try again.Īfter purging BOINC and its config files, reinstalling, rebooting all failed to work, I wiped the machine. I search for the issue and the only post I see with similar symptoms is this guy: It's still running CPU and GPU tasks in the background and is connecting with the network. This morning after a reboot, I'd click on BOINC's manager application and it didn't open.Ī few more clicks, a few restarts, no fix.
