Improved performance reduces time to solution of current simulations and allows frequency increase for more accurate modeling & imaging.
Continued advances in seismic modeling performance on Intel® architecture allow computational scientists to solve new and more complex problems.
ISO3DFD* is a finite difference kernel used to solve 3D acoustic isotropic wave equation for seismic modeling (acquisition design) and imaging (RTM, FWI). This is a 16th order in space (symmetric coefficient) and 2nd order in time scheme without boundary conditions.
iso3dfd*: version dev13 from Jan 2017. OS: Centos* 7.3.

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.
