	I don't know how the runtimes getting calculated: R888 - n=250-400k - runtime 52min-2h35min (AVX@3.8Ghz) - 250-300k = 375 credits - 300-350k = 525 credits - 350-400k = 700 credits - Sierpinski / Riesel Base app -average3 - deadline 3 days The runtime of 2h35min is definitly wrong, a 300-350k WU takes (at the moment) 2h45min on a 6700k running at 4.2GHz. http://srbase.my-firewall.org/sr5/result.php?resultid=216830294 Just guessing now but I think the 350-400k will take about 4h then. 525 credits for a (nearly) 3h WU seems to be very low. I recognized that before too, calculation time is set very low, real runtime is about calculated +10-50%. I have no idea how your 3.8GHz AVX CPU can do that in 2h35min. Just take the WU above and show me I am wrong.

You can find the calculation in FAQ, pls note that my CPU has a 6 memory channel controller so there is no bottleneck if you are running something on all cores. The test is only based on 1 core.

	is it possible to run srbase on a RPI3?
