Developed NCCL RDMA auto-discovery and NCCL_IB_HCA configurability for the ROCm/Megatron-LM repository, enhancing the portability and reliability of distributed training scripts. Leveraged shell scripting and networking expertise to implement automatic detection of local RDMA devices using 'rdma link -j', replacing static NCCL_IB_HCA lists and ensuring compatibility across diverse hardware environments. The solution preserved explicit user overrides and aligned with existing configuration patterns, preventing silent fallback to TCP on clusters lacking RDMA-capable NICs. This work improved trainer robustness in multi-node setups and streamlined deployment, demonstrating a strong grasp of distributed computing principles and practical shell scripting for system integration.
