The SPEChpc 2021 suite includes a broad swath of science and engineering codes that are representative (and portable ) across much of what we see in HPC.
- A tested set of benchmarks with performance measurement and validation built into the test harness.
- Benchmarks include full and mini applications covering a wide range of scientific domains and Fortran/C/C++ programming languages.
- Comprehensive support for multiple programming models, including MPI, MPI+OpenACC, MPI+OpenMP, and MPI+OpenMP with target offload.
- Support for most major compilers, MPI libraries, and different flavors of Linux operating systems.
- Four suites, Tiny, Small, Medium, and Large, with increasing workload sizes, allows for appropriate evaluation of different sized HPC systems, ranging from a single node to many thousands of nodes
