Dear all, this thursday Mark Adams will be giving an interesting talk on a new benchmarking metric for HPC systems, HPGMG. I'm sure it will be worthwhile attending! Lawrence

Hi all,

This week's seminar will be on Thursday the 9th June (a day early this week) in G38, at the normal time of 4pm where Mark Adams will be giving a talk titled

"High Performance Geometric Multigrid: A Supercomputer Benchmark and Metric".

The abstract is below.

Mark Adams and Sam Williams

The HPGMG project (hpgmg.org <http://www.hpgmg.org/>) develops the extreme-scale benchmark and metric - HPGMG - which is a compact, stand alone, conceptually simple, benchmark, modeled in many ways on HPL. HPGMG solves a system of linear algebraic equations; the metric is equations solved per second (HPL maps equations to floating operations to generate the familiar flops/sec metric). HPGMG solves a finite volume discretization of the Laplacian and uses an appropriate solution algorithm - the non-iterative form of multigrid (full multigrid). HPGMG is designed for use as both a ranking metric and an aid to computer designers for developing architectures, and to centers for configuring systems that are well balanced with respect to general sparse applications. We publish the list twice each year (during ISC and SC). We present a preview of the ISC16 list, which shows some rank reordering relative to the Top500 list, and includes the first GPU (MPI+OpenMP+CUDA) results running on Titan and Piz Daint.

See you there!

James & Roan
