Innovative Rotor Winding Geometry for Synchronous Machine By Means of Additive Manufacturing

This paper presents an innovative optimized rotor winding for an electrically excited synchronous motor by means of additive manufacturing (AM). The new coil geometry was designed with the purpose of maximizing the filling factor keeping the cross section area of the conductors constant as only constrain in the geometry definition. The proposed solution allow to increase the machine torque density for the same rotor Joule losses or to increase the efficiency of the machine for the same output...

Prediction of time-to-solution in material science simulations using deep learning

Predicting the time to solution for massively parallel scientific codes is a complex task. The reason for this is the presence of multiple, strongly interconnected algorithms that possibly react differently to the changes in compute power, vectorization length, memory and network bandwidth and latency and I/O throughput. A reliable prediction of execution time is however of great importance to the user who wants to plan on large scale simulations or virtual screening procedures characteristic...

COUNTDOWN - A run-time library for application-agnostic energy saving in MPI communication primitives

Energy and power consumption are prominent issues in today’s supercomputers and are foreseen as a limiting factor of future installations. In scientific computing, a significant amount of power is spent in the communication and synchronization-related idle times among distributed processes participating to the same application. However, due to the time scale at which communication happens, taking advantage of low-power states to reduce power in idle times in the computing resources, may intro...
