Olympus-HPC

Olympus-HPC is an open-source ecosystem for research and development in compiler and runtime systems for HPC and accelerators.

The ecosystem includes Proteus (LLVM-based JIT compilation) and Mneme (record–replay and performance experimentation).

Projects

• Proteus — LLVM-based JIT compilation engine.
• Mneme — Record–replay for GPU kernels.

Tutorial and Presentations

• Tutorial @CGO 2026 Quick guide on internals on both Proteus and Mneme slides
• LLVM Workshop @CGO 2026 A Short Tour of Mneme’s Core Capabilities slides
