Ok, so it will not solve the next quantum physics conundrum, but it might just ignite a spark in the next comp sci or physics genius. This is "Tiny Titan" designed at Oak Ridge National Laboratory specifically to get students thinking parallel. Writing software for massive high performance computing (HPC) systems is no easy task. With the simple hardware design built from low cost $35 Raspberry Pi boards and example projects a student can get their feet wet. On the Tiny Titan github there is example code in C and Python and lots of documentation.
