Worked on the ofiwg/libfabric repository to address concurrency issues in the TCP provider’s RDM operations. Focused on low-level system programming in C, the work involved fixing a data race by ensuring correct assignment of function pointers within the xnet_rdm_fid_ops structure. This targeted change improved the stability and correctness of RDM operation paths under parallel access, reducing the risk of instability caused by race conditions. The solution was delivered as a single, well-documented commit, making future maintenance straightforward. The approach demonstrated careful attention to concurrency and system-level details, contributing to the reliability of libfabric’s TCP provider in multi-threaded environments.
