SOURCE: INTEL MEASURED RESULTS AS OF DECEMBER, 2013
Application: NASA OVERFLOW* 2.2g; fluid flow using
overset grids,
Description OVERFLOW 2.2g is a three-dimensional
time-marching implicit Navier-Stokes code that can also
operate in two-dimensional or axisymmetric mode. The
code uses structured overset grid systems. More at

Overflow_Manuals.html
Availability:
• Code: Available here. Xeon Phi optimization (but not
build setup) is included in standard source code
available from NASA
• Recipe: Not available.
Usage Model: MPI/OpenMP* symmetric processing
distributed across an Intel® Xeon® processor and an Intel®
Xeon Phi coprocessor.
Results: Symmetric process demonstrated up to 1.2X
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
