There's a number of Linux distributions for ARM, as the Raspberry Pi project has several. Python, Ruby, Perl, NodeJS and a number of other tools are fully supported.
The multi-processing side, though, is probably not a standard CPU meaning you can't just throw Python code at it. You'll have to use CUDA or OpenCL techniques.
If you want a small ARM system, the Pi is a good place to start but the Beagle Board (http://beagleboard.org/) is a much better deal.
