SOURCE: INTEL MEASURED RESULTS AS OF SEPTEMBER, 2014<br />
Application: AMBER* 14<br />
Description: Bimolecular Simulations (Protein, DNA, RNA, virus<br />
etc.). Full double precision (DPDP). More at http://ambermd.org/<br />
Availability:<br />
• Code: Available as a patch.<br />
• Recipe: Available here (Section 18.7 of the manual).<br />
Usage Model:<br />
• Baseline is the Intel® Xeon® processor E5-2697 v2 host (also<br />
measured in<br />
http://ambermd.org/gpus/benchmarks.htm#Benchmarks) and<br />
speed up is shown with offload processing on both the Intel®<br />
Xeon® processor E5-2697 v2 and the Intel® Xeon Phi<br />
coprocessor 7120A.<br />
• Performance shown for the released code, all double precision,<br />
across the platforms. 50% workload on the host, 50% on the<br />
coprocessor.<br />
Highlights: The code had been optimized, will be delivered to<br />
the AMBER community (whoever has license) and available as<br />
update patch during code configuration.<br />
Results: Optimized offload process demonstrated up to 2.2X<br />
improved performance over the baseline Intel® Xeon® processor<br />
E5-2697 v2.<br />
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,<br />
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<br />
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<br />
