![]() ![]() Users can decide which projects they participate in, using the free and open-source BOINC client software. I'm only starting to play with the NDK and BRP will be on my list of additional apps to try and port.A subreddit dedicated to all things BOINC, a platform enabling the public to volunteer their computer's processing capability towards research projects distributed across the globe. On that note, I'd also be curious to see if have been doing any testing with NativeBOINC on Android. ARM users and enthusiasts? From what you're saying, the project team members are already trying these things anyway! Why not build more community awareness and interest in by setting up an ARM section in forums for Android, Raspbian, Archlinux, etc. The Raspberry Pi doesn't have the ARMv7 NEON instruction set (for example), but it's popular, it's ARM, and it's cheap. Should you guys officially support Raspberry Pi over at I think that projects should support ARMv6 and ARMv7 in general or at least provide some sort of community direction. Definitely not a candidate compared to which took ~2 days. It's taking quite a while to get this task done. In regards to the performance, you're not wrong. I haven't got around to setting up a GIT repo yet. I will respect the GPL licensing requirements and post what I can. I don't remember modifying any source, however, I did change the compile options when I manually compiled with g++. Pulsars are spinning 'neutron stars', extremely dense remnants of stars after they collapse in a Super Nova (for stars that are not heavy enough to collapse even further into Black Holes). Secondary searches involve more conventional objectives like discovering new pulsars in data from radio telescopes like Arecibo (Puerto Rico) and Parkes (Australia), and so far almost 50 such discoveries have been announced by Another search is looking at data from the FERMI spacecraft to discover pulsars in gamma-ray detector data. A 'Gravitational Wave' is a phenomenon that was predicted by Albert Einstein almost 100 years ago as a consequence of General Relativity, but are extremely difficult to measure directly, something that still needs to be done. P.S.: Some more background information on primary goal of is analysing data from Gravitational Wave detectors like LIGO in the US. (working for the Max-Planck-Institute of Gravitational Physics, Hannover, Germany) Who knows, you could be the first one to discover a celestial body on a Raspi (all discoverers get a framed certificate and are mentioned in the scientific publication that describes the discovery). But this will not happen in 2012, maybe in the first half of 2013.Īnyway, nuff of the rambling: if you are interested in beta-testing on your Raspi, let me know in this forum and if there is sufficient interest I can put together a HOWTO. ) we would be able to generate tasks that are 1/8 the size of current tasks, so they would complete in under two days). With some modifications to our project infrastructure (work generators, task validators. ![]() So I'm not quite sure if anyone would really care to run on the Raspi in the current form and whether it would make sense to offer an official app for it, given the long crunching time. Too bad we cannot use the GPU on the Raspi for general purpose calculations (FFT would be the most interesting thing to put on the GPU in this case). I am currently working on some improvements that would bring the completion time closer to 10 CPU days. The deadline for returning results is 14 days, so you would have to run on a Raspi almost 24/7 to meet the deadline. There is also a GPU version of the BRP4 app for NVIDIA and ATI/AMD card, and there a task takes only 12 minutes or less on a fast card.For comparison: On a mid-range PC with a (multicore) Intel CPU, each core can finish a BRP4 task in roughly 12 hours.On a Raspi overclocked to 950 Mhz, a BRP4 task finished in 12 days.Of course, the ARMv6 was never meant to be a number cruncher, so the performance is, well, moderate : With rather minor modifications of the build scripts and the application source code itself, I got the BRP4 search app compiled and running on the Raspi. We currently do not support ARM CPUs, but the source code for the app that would run best on the RasPi, the BRP4 search for radio pulsars, is under GPL open source license and therefore readily available, ports to other platforms are welcome.Īfter getting my own Raspi, I just couldn't resist to try on it (under Raspian), just for the fun of it. ![]() I'm one of the project admins and scientific software engineers at the BOINC project. ![]()
