Prerona Ghosh contributed to the ROCm/rocm-systems repository by developing runtime emulator mode detection, dynamic configuration, and lightweight GPU core dump features. She refactored concurrency and memory management using C++ standard mutexes and smart pointers, improving stability and performance. Her work included implementing a shared queue pool API, resolving memory leaks in signal and trap handling, and enabling configurable queue sizing for flexible workload tuning. Prerona also enhanced debugging by introducing code object memory tracking and a test suite for GPU device identification. Her engineering demonstrated depth in C++ development, GPU programming, and low-level system programming, resulting in robust, maintainable solutions.

Mar 1, 2026March 2026 monthly summary for ROCm/rocm-systems: Delivered two major features enhancing GPU debugging and device identification. Key outcomes include improved memory management for lightweight GPU coredumps through code object memory tracking, and increased reliability of GPU device identification via a new test suite validating secondary CUID values. These efforts reduce debugging time, improve memory accounting accuracy, and strengthen device telemetry across ROCm GPUs. Demonstrated skills include low-level instrumentation, memory tracking, test framework development, and CI-level validation of CUIDs. Impact: improved stability and observability, enabling faster triage and robust deployments in GPU compute environments.

Feb 1, 2026February 2026: Delivered Lightweight GPU Core Dump and Memory State Retrieval feature for ROCm/rocm-systems, enabling efficient memory tracking and state capture during core dumps. The work included driver-level enhancements to speed memory address lookups and introduced new methods to gather queue save area information. Core changes are captured in commit e0af8a0e66c77c9cd6335f9509b425ddfe2e777f, which changes memory-lookup from vector to map and uses thunk calls through the driver code for improved performance.

Oct 1, 2025Implemented runtime emulator mode detection and configuration within ROCm/rocm-systems, replacing compile-time conditionals to enable dynamic behavior based on detected mode. Centralized the detection logic, moving the check to main.cc, and introduced a reusable mode-check function applicable to each sample. This work reduces complexity, improves maintainability, and enhances testing flexibility for emulator environments.
