... it also depends greatly on 'how many' PI 2 units are crunching -
Any project that can be built from sources will run on PI 2 also, as long as you have the dependencies on-board. If you don't have the sources, and the project isn't built for the Arm, then you're out of luck.
Check with the DC project and see if they have and arm build... see if anyone has built from sources for the RPi; as a side note, the RPi is a significant improvement in processing power about 6x faster... has four cores, as a for instance my PI b+ computes PI to 10,000+ places in 1m58s using python3 and pdeclib. My PI 2 computes PI to 10,000+ places in 1m12s !
Keep in mind the RPi was not designed as a high speed number cruncher... it was designed to help kids learn to program, and to help everyone learn how to connect a computer to the real hardware world.... so YMMV
