Cray’s work with the ISVs has involved profiling applications to enhance scaling throughout the code and for a broad range of simulation features. The joint effort between the system experts and the ISVs is crucial since the ISVs typically do not have the compute resources to test performance on thousands of cores. Also, Cray has been able to work with the ISVs, and leading users, to demonstrate extreme scaling on production models. These runs often require “cpu months” (24 hours/day x30 days = 720 hours) of compute time, but when using thousands of cores per simulation, this can be turned around in less than a day.
Clifford goes on to say that extreme scaling is the only way to achieve today’s performance potential for a broad range of simulation so that CAE will add even more value to the product design process.
