Manufacturing Bits: March 19


Exascale computers Intel and the U.S. Department of Energy (DOE) have set plans to develop and deliver the first exascale supercomputer in the United States. The system, called Aurora, will provide an exaFLOP of performance or a quintillion floating point computations per second. Targeted for delivery in 2021, the system is being developed at DOE’s Argonne National Laboratory. The system ... » read more

Isambard Analysis of HPC-Optimized Arm Processors


Written by Simon McIntosh‐Smith, James Price, Tom Deakin, Andrei Poenaru (all from the High Performance Computing Research Group, Department of Computer Science, University of Bristol, Bristol, UK) In this paper, we present performance results from Isambard, the first production supercomputer to be based on Arm CPUs that have been optimized specifically for HPC. Isambard is the first Cray ... » read more

Cluster Scalability Of ANSYS Fluent 12.0 For A Large Aerodynamics Case On The Darwin Supercomputer


This work examines the parallel scalability characteristics of commercial CFD software ANSYS FLUENT 12 for up to 256 processing cores, for transient CFD simulations that are heavy in I/O relative to numerical operations. In studies conducted with engineering contributions from the University of Cambridge and ANSYS, the Linux HPC environment named Darwin combined an Intel Xeon cluster with a P... » read more
