Description
Dr. Ryutaro Himeno, Director of the Advanced Center for Computing and Communication, has developed this benchmark to evaluate performance of incompressible fluid analysis code. This benchmark program takes measurements to proceed major loops in solving the Poisson’s equation solution using the Jacobi iteration method.
Being the code very simple and easy to compile and to execute, users can measure actual speed (in MFLOPS) immediately.

The benchmark is used in some recent HPC papers and presentations including:
- Fugaku: the First ‘Exascale’ Machine (page 10)
- Performance Evaluation of a Vector Supercomputer SX-Aurora TSUBASA
The benchmark appears closely related to the current Poisson2d benchmark, but instead features a 3D Jacobi stencil.
I've seen similar (MPI-enabled) Jacobi benchmarks before in the book of Hager & Wellein, Introduction to High Performance Computing for Scientists and Engineers.
