Feb 1, 2026February 2026 — Key delivery: Compiler Cache Statistics and Monitoring for clcache in intel/compute-runtime. Implemented a stats telemetry system with per-directory stats files, an enable/disable environment variable, and a CacheStats structure tracking hits, misses, and cache version. Real-time updates propagate to a central clcache/stats directory, enabling proactive cache tuning and performance dashboards. This work, aligned with NEO-11760, reduces rebuild times through better cache visibility and establishes a foundation for centralized monitoring. Demonstrates strong systems programming, telemetry instrumentation, and environment-configurable data propagation.

Jan 1, 2026January 2026 (2026-01): Focused development in intel/compute-runtime around cache management experimentation and cross-platform portability. Implemented an initial cache tree structure to organize cached files by the first two letters of their names, enabling scalable cache lookup and management. This work included two feature commits (2f2f17a47917f41589ad8b634330b3fbb6fcd243 and 2ea5a9b6c48e3826c45508598d240076d9712330) and was subsequently reverted due to unmet requirements (d7ad81b09df2ed514aa0364cdcc4d7b491a29b65). Additionally, introduced a fix to use full include paths for elements_struct.h to ensure Windows and Linux builds locate headers reliably (ed592d49885d9356868e82b5f31e808033c1f6a9). These efforts enhanced cross-platform reliability and provided a foundation for a robust cache design.
