arm

I am using some RaspberryPI boards for a data acquisition system. They are nice boards, with plenty of community support around them, but they are really slow. I am thinking of gradually replacing them with ODROID multicore boards, with the Samsung Exynos processors.

I have some experience using taskset to set CPU affinity on my servers because I am always running Node.js applications that are by definition single threaded.

Now, is it possible to do this on an ARM board? I do not see why it would not in theory, but I have doubts over how well it is going to work.

Does anyone have experience with this kind of hack? Also, I would appreciate any comments about ARM CPUs and how they differ from x86.
