PROFILE

Łukasz Ślusarczyk

Lukasz Slusarczyk developed and enhanced benchmarking and runtime systems across the intel/compute-benchmarks and oneapi-src/unified-runtime repositories, focusing on performance measurement, build stability, and developer productivity. He implemented kernel submission benchmarks for Torch Benchmark, integrating C++ and OpenCL to evaluate shared local memory and memory reuse scenarios. Lukasz improved CI reliability by refining CMake configurations and addressing environment-specific build issues, leveraging Python for packaging and scripting tasks. His work included dynamic device management for Level Zero memory providers and advanced logging for debugging, demonstrating depth in low-level programming, concurrency, and performance optimization while delivering maintainable, reproducible solutions for complex benchmarking workflows.

Work History

January 2026

2 Commits • 1 Features

Jan 1, 2026

January 2026 monthly summary: Delivered targeted performance measurement upgrades and build stability fixes across two repositories, enhancing benchmarking reliability and onboarding efficiency, with measurable business value in faster optimization cycles and reduced environment-related failures.

December 2025

Dec 1, 2025

December 2025: Delivered kernel submission benchmarks for the Torch Benchmark suite in the intel/compute-benchmarks repository. Implemented (1) a kernel-submit-slm benchmark to evaluate performance with a specified Shared Local Memory (SLM) size, and (2) a kernel submit memory reuse benchmark to measure performance when memory reuse is employed. These additions broaden performance characterization capabilities for kernel-level workloads and support data-driven optimization decisions. No major bugs fixed this month; focus was on feature delivery, validation, and contributing robust benchmarks. Business value: enhanced benchmarking coverage, faster performance characterization, and clearer guidance for kernel-level optimizations. Technologies/skills demonstrated: Torch Benchmark integration, SLM-aware performance measurement, memory reuse evaluation, and disciplined code contributions with signed-off commits.

Aug 1, 2025

Monthly summary for 2025-08 focusing on the oneapi-src/unified-memory-framework feature delivery. The primary accomplishment was adding dynamic resident devices management for the Level Zero memory provider, enabling runtime addition/removal of resident devices, with new management APIs and updated provider logic to handle live residency changes. This work improves resource utilization, reduces downtime during dynamic workload shifts, and lays groundwork for future dynamic memory scenarios.

July 2025

1 Commits

Jul 1, 2025

July 2025 monthly summary for the intel/compute-benchmarks repository focusing on build stabilization and CMake configuration improvements. The main delivery was stabilizing the build process by addressing warnings, updating CMake configuration, and aligning compiler settings. The work also includes refactoring test instantiation and removing unused variables to improve reliability and maintainability of the benchmark suite. These changes reduce CI noise, improve build correctness across environments, and enable faster onboarding for new contributors.
