PROFILE
M Kelly
Mark Kelly contributed to the hpcc-systems/HPCC-Platform repository by engineering robust backend features and resolving complex bugs across networking, caching, and system configuration domains. He developed disk-based page caching to enhance scalability, implemented dynamic priority management for query responsiveness, and improved process termination for graceful shutdowns. Using C++ and CMake, Mark refactored socket I/O statistics for better observability, strengthened error handling in secure sockets, and optimized startup performance under high concurrency. His work demonstrated depth in system programming, Linux internals, and performance tuning, consistently delivering maintainable solutions that improved reliability, monitoring accuracy, and operational flexibility for large-scale deployments.

Jul 1, 2025July 2025: Stabilized Roxie operations in the HPCC-Platform by delivering targeted reliability and observability improvements. Implemented UDP message monitoring enhancements to detect and log duplicate completed messages, with periodic aggregation and a reset mechanism, and tuned timeout visibility to strengthen issue detection in message handling. Hardened startup and port-conflict behavior for Roxie with an isRunning check, improved socket error handling, and guaranteed graceful termination on startup failure. These changes reduce downtime, improve diagnostic visibility, and enhance the robustness of the Roxie processing pipeline for production workloads.

Mar 1, 2025March 2025 monthly summary for hpcc-systems/HPCC-Platform focusing on socket I/O statistics enhancements. Key work: refactor socket statistics tracking by moving the SocketStats structure to jsocket.hpp, add a getStatistic method, and update CSocket::getStatistic to delegate to it. CSecureSocket now includes a SocketStats member and updates statistics during read/write operations to measure secure socket I/O more accurately. Commit HPCC-33682 (ff3add291202637ebafcd56768bc6dc03285fa0a) enabled improved observability of socket metrics.

Feb 1, 2025February 2025 — HPCC Platform (hpcc-systems/HPCC-Platform). Key feature delivered: Build System Flexibility by removing the explicit CMake minimum version directive (cmake_minimum_required(VERSION 2.8)) to enable automatic detection and use of newer CMake versions (3.31+). This aligns the project with updated environments, CI pipelines, and reduces maintenance burden for future upgrades. Commit reference: HPCC-33460: 'HPCC-33460 Build on ubuntu 22.04 with CMake version 3.31+' (hash 9430b6c81d1845f0964137d07256c697f5557f49). No critical bugs reported this month. Overall impact: Smoother onboarding for new environments, improved build portability, and greater resilience to upstream toolchain changes. Technologies/skills demonstrated: CMake version handling, Linux/Ubuntu 22.04 compatibility, build-system maintenance, version-detection strategies.
