The High-Performance Conjugate Gradients (HPCG) benchmark is part of the TOP500 computer ranking system, complementing LINPACK. I am the designer and developer of the reference code. HPCG was a 2019 R&D 100 Honorable Mention project.

The two key reports that describe HPCG are:

• Toward a New Metric for Ranking High Performance Computing Systems
• HPCG Technical Specification
