In this paper we present a new accounting model for heterogeneous supercomputers. An increasing number of supercomputing centres adopt heterogeneous architectures consisting of CPUs and hardware accelerators for their systems. Accounting models using the core hour as unit of measure are redefined to provide an appropriate charging rate based on the computing performance of different processing elements, as well as their energy efficiency and purchase price. In this paper we provide an overview…

A Metric for Evaluating Supercomputer Performance in the Era of Extreme Heterogeneity
TLDR
The purpose of this paper is to describe a single performance metric for a heterogeneous system, which describes how the National Energy Research Scientific Computing Center (NERSC) evaluated the Cori supercomputer, which contains two node types, nodes based on dual-socket Intel Xeon (Haswell) processors and node based on Intel Xeon Phi (Knights Landing) processors.
Thermal design power and vectorized instructions behavior
TLDR
The study shows that, because of processor frequency, performance and power consumption are strongly related to thermal design power and shows that AVX512 has unexpected behavior regarding processor power consumption, while DRAM power consumption is impacted by SIMD instructions because of the generated memory throughput.
Visualizing the world's largest turbulence simulation
TLDR
The visualizations brilliantly showcase the stretching-and-folding mechanisms through which astrophysical processes such as supernova explosions drive turbulence and amplify the magnetic field in the interstellar gas, and how the first structures, the seeds of newborn stars are shaped by this process.
