Application: GROMACS* 5.0-RC1; Workload: 512K H2O with RF
method
Description: GROMACS is a versatile package to perform
molecular dynamics, i.e. simulate the Newtonian equations of
motion for systems with hundreds to millions of particles. It is
one of the fastest and the most popular Molecular Dynamics
packages.
Availability:
• Code: Version 5.0-rc1 available here and here.
• Recipe: Available here.
Highlights:
• Highly optimized for Intel® Xeon® Processors (AVX-intrinsics).
• Able to run full simulation on Intel® Xeon Phi coprocessor
natively + host processor using a symmetric model.
• Optimized with intrinsics for 512-bit vectorization on Intel
Xeon Phi coprocessors.
• Results: Symmetric process demonstrated up to 1.79X
improved performance over the baseline Intel® Xeon®
processor E5-2697 v2.

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
