Competition Applications

Benchmarks

LINPACK Benchmark

The Linpack Benchmark is a measure of a computer’s floating-point rate of execution. It is determined by running a computer program that solves a dense system of linear equations. It is used by the TOP 500 as a tool to rank peak performance. The benchmark allows the user to scale the size of the problem and to optimize the software in order to achieve the best performance for a given machine. This performance does not reflect the overall performance of a given system, as no single number ever can. It does, however, reflect the performance of a dedicated system for solving a dense system of linear equations. Since the problem is very regular, the performance achieved is quite high, and the performance numbers give a good correction of peak performance.

HPCG Benchmark

The High Performance Conjugate Gradients (HPCG) Benchmark project is an effort to create a new metric for ranking HPC systems. HPCG is intended as a complement to the High Performance LINPACK (HPL) benchmark, currently used to rank the TOP500 computing systems. The computational and data access patterns of HPL are still representative of some important scalable applications, but not all. HPCG is designed to exercise computational and data access patterns that more closely match a different and broad set of important applications, and to give incentive to computer system designers to invest in capabilities that will have impact on the collective performance of these applications.

IO500 Benchmark

The IO500 benchmark is a benchmark suite for High-Performance IO. It harnesses existing and trusted open-source benchmarks such as IOR and MDTest and bundles execution rules and multiple workloads with the purpose to evaluate and analyze the storage devices for various IO patterns. The IO500 benchmark is designed to provide performance boundaries of the storage for HPC applications regarding data and metadata operations under what are commonly observed to be both easy and difficult IO patterns from multiple concurrent clients. Moreover, there is a phase that scans for previously-created files that match certain conditions using a (possibly file system-specific) parallel find utility to evaluate the speed of namespace traversal and file attribute retrieval. The final score that is used to rank submissions in the list is a combined score across all the executed benchmarks.

Applications

Cardioid

Cardioid is a cardiac simulation suite for simulating clinical cardiac phenomena. It is capable of simulating both electrophysiological and mechanical organ-level simulations, and has processing tools for computing cardiac meshes, reconstructions of torso ECGs, and generating realistic cardiac fiber orientations. The Cardioid electrophysiology solver was a Gordon Bell finalist and has strong-scaled to all of the Vulcan supercomputer for a clinically relevant problem. The code is parallelized using MPI, and has separate optimized loops for taking advantage of OpenMP, SIMD instruction sets for CPU architectures, and CUDA for GPU architectures.

Quantum ESPRESSO

Quantum ESPRESSO is a software package for first-principles electronic-structure calculations and materials modeling based on density-functional theory, plane wave basis sets, and pseudopotentials

Mystery Application

At the start of the competition, teams will be given an application and datasets for a mystery application. Students will be expected to build, optimize and run this mystery application all at the competition.

Reproducibility Challenge

One of the applications presented to the student teams is the Reproducibility Challenge, in which students attempt to reproduce results from an accepted paper from the prior year’s Technical Program.

Students have the opportunity to interact directly with the paper’s authors as they attempt to reproduce specific results and conclusions from the paper. As part of this challenge, each student team writes a reproducibility report detailing their experience in reproducing the results from the paper. Authors of the most highly rated reproducibility reports may be invited to submit their reports to a reproducibility special issue.
