Application: NWChem* is a computational chemistry software
package that includes quantum chemical and molecular
dynamics functionality. NWChem is developed the
Environmental Molecular Sciences Laboratory (EMSL) at
the Pacific Northwest National Laboratory (PNNL). More at

Availability:
• Code: Available here and from the SVN repository.
• Recipe: Available here.
Usage Model: Offload using LEO and OpenMP*
Highlights: NWChem with Intel® Xeon Phi coprocessor 7120A
offloading is a compelling and cluster compelling application for
the NWChem community .
Results: Compared to the NWChem* 6.3rev2 and Intel® Xeon®
processor E5-2697 v2 baseline:
1) NWChem 6.5 CCSD(T) performed up to 1.24X faster with the
Intel® Xeon® processor E5-2697 v2.
2) 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.

Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems,
components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated
purchases, including the performance of that product when combined with other products. For more information go to http://www.intel.com/performance *Other names and brands may be claimed as the property of others
