An Ubuntu 22.04 LTS-based OCI image for running HPL, a portable implementation of the High-Performance Linpack Benchmark for Distributed-Memory Computers. HPL is used to benchmark the Top 500 supercomputers.
The High-Performance Linpack (HPL) OCI image provides a containerised xhpl binary that
can be used to run the Linpack benchmark on your distributed-memory system. OpenBLAS, ATLAS,
mpich, and libfabric are installed inside this image to support the xhpl binary.
This short usage how-to section assumes that you have Sarus installed on your distributed-memory system, however, this image should work with any OCI-compliant container runtime.
