May 2025 — Containers/ramalama: Delivered two high-impact changes that boost LLM scalability and ROCm/HIP reliability. Implemented Large Language Model Multi-Part File Support for llama.cpp, enabling loading and mounting of models split across files to handle sizes beyond a single-file limit. Fixed ROCm/HIP compatibility by updating the llama.cpp library SHA in the build script. These efforts raise usable model size, improve deployment stability, and reduce operational risk. Technologies demonstrated include llama.cpp integration, build-script maintenance, and version-pinning for critical dependencies.

April 2025 focused on reliability, compatibility, and feature expansion for containers/ramalama. Key outcomes include upgrading container bases to Fedora 42 for current packages and better security, enabling distributed inference via Llama RPC in containers, and adding draft model support to ramalama-serve. Runtime improvements include ensuring Jinja templating is applied during runs and stabilizing tests with explicit parameters. In parallel, multiple container build fixes were addressed to improve image reliability and CI consistency, reducing maintenance overhead and deployment risk.

In January 2025, delivered improvements to CPU detection reliability and test reusability within linux-test-project/ltp. Implemented a reusable get_numcpus utility exposed via a shared library, enabling consistent CPU detection across tests and tools. Updated tests and usage points (including sched_football) to consume the shared function for accurate CPU counts across diverse hardware configurations. Fixed a memory leak in get_numcpus by freeing the allocated cpuset before returning, enhancing stability under varied workloads. These changes reduce duplication, improve test accuracy in heterogeneous environments, and strengthen overall test infrastructure.
