PROFILE

Ylachman

Over four months, contributed to the intel/pti-gpu repository by developing and refining advanced profiling and tracing features for GPU workloads. Delivered a profiling data collection control that enables pausing and resuming metric queries, reducing overhead and improving diagnostics. Enhanced kernel instrumentation by adding Level Zero API support for argument-based launches and introduced selective tracing for MPI ranks and devices, improving performance tuning in parallel environments. Addressed concurrency issues through improved event handling and command-list management. Implemented a cross-platform shared memory control interface for memory profiling and refactored MPI rank retrieval for efficiency, leveraging C++, Python scripting, and system programming expertise.

Dec 1, 2025

December 2025 monthly summary for intel/pti-gpu: Delivered critical instrumentation and tracing enhancements with a focus on business value and stability. Key feature work includes Unitrace Level 0 API support for launching kernels with arguments, enabling deeper kernel-launch instrumentation, and the introduction of selective tracing for the Ze collector to target specific MPI ranks and devices. A major reliability improvement fixed a hang when running tests with multiple concurrent launches by tightening event handling and command-list lifecycle. Together, these changes reduce profiling overhead, improve diagnostic fidelity, and enable more precise performance tuning in multi-device/multi-rank environments. Technologies demonstrated include Level Zero API, Unitrace tooling, MPI-based tracing, header/tooling updates, and robust event/command-list synchronization.
