Application: miniGhost v. 0.9
Description: Finite Difference mini-application which
implements a difference stencil across a homogenous three
dimensional domain. More at https://mantevo.org/download/
Availability:
• Code: Available here or here.
• Recipe: Available here.
Usage Model: Symmetric model.
Highlights: The code is a proxy for the CTH (shock physics
code) and can be used as a good test-case to measure network
(interconnect bandwidth vs. latency) performance.

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
