NWChem*

A computational chemistry software package that includes quantum chemical and molecular dynamics functionality.

Performance Increased by up to 1.52x1

NWChem* is designed for high-performance parallel supercomputers and aims to be scalable both in its ability to treat large problems efficiently, and in its usage of available parallel computing resources. It is actively developed by a consortium of developers and maintained by the Environmental Molecular Sciences Laboratory (EMSL) located at the Pacific Northwest National Laboratory (PNNL) in Washington state.

Current support for Intel® Xeon Phi™ coprocessors is included in NWChem* 6.5 or later. The latest development version might contain additional NWChem*
modules with support for the Intel® Xeon Phi™ coprocessor. 

Check the release notes and NWChem* documentation for further information.

Performance Results

NWChem* 6.3rev2 CCSD(T) performed up to 1.35X faster with the Intel® Xeon® processor E5-2697 v2 and the Intel® Xeon Phi™ coprocessor 7120A compared to the Intel® Xeon® processor E5-2697 v2 baseline.

Compared to the NWChem 6.3rev2* and Intel® Xeon® processor E5-2697 v2 baseline, NWChem 6.5 CCSD(T) performed up to 1.52X faster with the Intel® Xeon® processor E5-2697 v2 and the Intel® Xeon Phi™ coprocessor 7120A.

Informazioni su prodotti e prestazioni

1

I risultati dei benchmark sono stati ottenuti prima dell'implementazione delle patch software e degli aggiornamenti firmware più recenti volti a risolvere gli exploit denominati "Spectre" e "Meltdown". Con l'implementazione di tali aggiornamenti i risultati potrebbero non essere applicabili al dispositivo o al sistema in uso.

Il software e i carichi di lavoro utilizzati nei test delle prestazioni possono essere stati ottimizzati per le prestazioni solo su microprocessori Intel®. I test delle prestazioni, come SYSmark* e MobileMark*, sono calcolati utilizzando specifici sistemi computer, componenti, software, operazioni e funzioni. Qualunque variazione in uno di questi fattori può comportare risultati diversi. Consultare altre fonti di informazione e altri test delle prestazioni per una valutazione completa dei prodotti che si desidera acquistare, comprese le prestazioni di tali prodotti se abbinati ad altri prodotti.
