You will have to purchase additional USB equipment tho (a radioactivity detector and accelerometers, respectively). Note that there are two projects that explicitly, out of the box, support Raspberry PI, and both do not require heavy number crunching: and QuakeCatcherNetwork, which track environmental radioactivity levels and earth quakes, respectively. Newer ARM CPUs do have true vector units (NEON), but the Raspi's ARMv6 doesn't. The Raspi has a floating point hardware that, while it is called "vector-something", isn't really a typically vector unit as it doesn't really speed up calculations by doing several operations in parallel. the SSE vector units that every Intel CPU since The Pentium III (or even earlier) had and that can compute 4 floating point calculations at once.

I'm not sure whether the BOINC benchmark makes full use of the PCs hardware, e.g. The factor 20 is roughly what I got for my experiments. Such a shame that Seti can't use the RPi's GPU, because it's a fast one.Īs for the BOINC benchmark, it is a bit misleading. This does not really reflect what the benchmarks have measured, I guess the GPU makes the difference. Now this means that the home computer is actually roughly 20 times faster (can complete 20 tasks while the RPi completes one). But it seems that the home computer is only 7.3 times faster when it comes to floating point ops and only 5.7 times faster when it comes to integer ops.Īlso, as I wrote earlier, the Pi will likely complete a task in 3 days, while the home computer will complete one on each core (two in total) in 7.5 hours. I would have expected a bigger difference in performance between the two. Measured integer speedĕ488.69 million ops/sec Measured floating point speedđ732.37 million ops/sec Home computer (Intel Core2 Duo CPU 6300 1.86GHz, dual core): Measured integer speedę65.16 million ops/sec Measured floating point speedĒ37.25 million ops/sec Raspberry Pi (700 MHz ARM CPU, single core): Here's some data for comparing the performance (according to BOINC measurements) of my Raspberry Pi and my home computer: I'm very fond of my Pi, I don't want to endanger it in any way Besides, 2.5 days for a task or 3 days. Open boincmgr once from commandline and switch to advanced view (password on commandline always works as demonstrated above) Close Manager (Ctrl + Q) Make sure guirpcauth. If I had the money, I would so set up 40 of these things running SETI tasks - just for funnies.īy the way, I can report that a Raspberry Pi SETI job validated for me. Took ~2.5 days for SETI task to complete.
If you have something that could act as a heatsink for those chips you could probably take it up to 1000MHz.Ģ 00:40:23 323 floating point MIPS (Whetstone) per CPUĢ 00:40:23 1275 integer MIPS (Dhrystone) per CPU Recently here Ive set the general BOINC CPU usage setting to 100 and theDcarrion87 need to ramp that baby up to at least 950MHz (if you're prepared to void warranty).
