Worked on the ROCm/rccl repository to develop the ProxyTrace feature, enabling detailed monitoring of proxy events for send and receive operations. The implementation involved integrating new instrumentation logic into existing proxy code, using C and C++ to add header and source files that support in-host diagnostics. ProxyTrace stores a bounded set of active proxy operations in host memory, which helps reduce debugging noise and prevents unbounded memory growth during failures. This approach improved the reliability and performance monitoring of distributed systems, allowing for faster diagnosis of proxy-related issues and more stable communication paths between system components.
