Assume that networking infrastructure costs are negligible and server costs increase by a factor of 1.75x for each doubling of processors within the server (1.75 for 2 processors cores, 3.06x for 4 cores) no servers are currently available with more than 32 cores. Provide an architectural recommendation (number of nodes and number of cores per server) to FractalFutures that provides the best performance per dollar. Justify your answer and show your work.
