Application: ROMS idealized southern ocean benchmark; ROMS 3.6+
(svn version 709)
Description: ROMS is a free-surface, terrain-following, primitive
equations ocean model that employs a split-explicit time-stepping
scheme with special treatment and coupling between barotropic (fast)
and baroclinic (slow) modes. The benchmark input file is
“ocean_benchmark3.in” (distributed with publically available ROMS
source code), modified to increase horizontal resolution in X and Y. See
more at https://www.myroms.org/
Availability:
• Code: Available here. Patch available here (commit 37b3c86 applied).
• Recipe: Not available. Check for future availability at here.
Usage Model: Baseline is an Intel® Xeon® processor host only and
speedup is shown with symmetric processing on the Intel Xeon
processor the Intel® Xeon Phi coprocessor. Double precision code
across the platforms.
Highlights: The code has been optimized and will be available to the
ROMS community as an update patch.
Results: Symmetric process demonstrated 1.31X improved
performance with the Intel Xeon processor E5-2697 v2 (host) and the
Intel Xeon Phi coprocessor 7120A over the baseline host.

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
