Quantum ESPRESSO*

An integrated suite of open-source computer codes for electronic-structure calculations and materials modeling at the nano scale.

Speedup Increased 1.4X1

Quantum ESPRESSO* is coordinated by the Quantum ESPRESSO Foundation of which the CINECA National Supercomputing Centre (Bologna) is a member. Quantum ESPRESSO has a growing worldwide user community in academic and industrial research. ESPRESSO is an acronym for opEn-Source Package for Research in Electronic Structure, Simulation, and Optimization*. Its intensive use of dense mathematical routines makes it an ideal candidate for manycore architectures, such as the Intel® Xeon Phi™ coprocessor.

Quantum ESPRESSO is based on density-functional theory, plane waves, and pseudopotentials. It has evolved into a distribution of independent and interoperable codes in the spirit of an open-source project.

Running Quantum ESPRESSO code version 5.0.2+ on the Intel® Xeon Phi™ coprocessor requires minimal modifications in the Quantum ESPRESSO build process and no Quantum ESPRESSO source modifications.

GRIR443 is a public PRACE benchmark suited for multi-node execution. AUSURF112 is a publicly available DEISA benchmark suited for single-node execution.

Performance Results

Quantum ESPRESSO* 5.0.3 GRIR443 performed up to 1.4X faster with the Intel® Xeon® processor E5-2697 v2 and the Intel® Xeon Phi™ coprocessor compared to the Intel® Xeon® processor E5-2697 v2 baseline.

Quantum ESPRESSO* 5.0.3 AUSURF112 performed up to 1.2X faster with the Intel® Xeon® processor E5-2697 v2 and the Intel® Xeon Phi™ coprocessor compared to the Intel® Xeon® processor E5-2697 v2 baseline.

Los resultados de análisis se obtuvieron antes de la aplicación de los parches de software y actualizaciones de firmware más recientes, pensados para solucionar los ataques "Spectre" y "Meltdown". Puede que, al implementar estas actualizaciones, los resultados mostrados no sean aplicables a su dispositivo o sistema.

El software y las cargas de trabajo utilizadas en las pruebas de rendimiento han sido optimizados para el rendimiento solamente en microprocesadores Intel®. Las pruebas de rendimiento, como SYSmark* y MobileMark*, se han medido utilizando sistemas, componentes, software, operaciones y funciones informáticas específicas. Cualquier cambio realizado en cualquiera de estos factores puede hacer que los resultados varíen. Es conveniente consultar otras fuentes de información y pruebas de rendimiento que le ayudarán a evaluar a fondo sus posibles compras, incluyendo el rendimiento de un producto concreto en combinación con otros.
