Application: ISO 3DFD* 16th order Isotropic kernel.
Description: ISO 3DFD is a kernel that computes an isotropic
wave propagation in 3D (ISO). These kernel types are the heart of
Reverse Time Migration (RTM). RTM can also be computed with
VTI or TTI kernels. ISO 3DFD computes the wave propagation in
the 16th order in space and 2nd order in time. On a single Intel®
Xeon Phi coprocessor, this kernel is able to update around 5800
Mcells/s (350 Gflops).
Availability:
• Code: Not available.
• Recipe: Available here.
Usage Model: Native mode with intrinsics. OpenMP* but no MPI.
Results: The Intel® Xeon Phi coprocessor increased
performance by up to 1.66X compared to the Intel® Xeon®
processor E5-2697 v2.
Intel® Xeon Phi Coprocessor 7120A (native 244T)

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
