For under 6000 euro, the ASTRA research group managed to create a new personal desktop supercomputer that can do their tomography reconstruction calculations four times faster than a four-year old 3.5 million euro supercomputer. Some stability issues still need to be solved, but it’s clear that it’s worth all the hard work as the computing power, the performance per euro and the energy efficiency of FASTRA II is stunning.
