Solution Performance

Amber* is a suite of programs for classical molecular dynamics and statistical analysis. The main MD program is PMEMD (Particle Mesh Ewald Molecular Dynamics) employs two separate algorithms for implicit (generalized born or GB)- and explicit-solvent (PME) dynamics.

Hardware at-a-glance: Intel® Xeon® Gold 6148 processor

Platform features: Intel® Advanced Vector Extensions 512 (Intel® AVX-512), more cores, increased memory bandwidth

Software tools/libraries: Intel® MPI Library, Intel® Parallel Studio XE 2017 Composer Edition (C++/Fortran)

Product and Performance Information

-DMIC2 enable optimization for AVX512 vectorization, SPDP mixed precision, OpenMP optimization, but not any specific optimization for KNL arch.


Benchmark results were obtained prior to implementation of recent software patches and firmware updates intended to address exploits referred to as "Spectre" and "Meltdown". Implementation of these updates may make these results inapplicable to your device or system. 

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.
