Worked on the ROCm/ROCR-Runtime repository to address a memory allocation bug that limited dmabuf export to only the first GPU in multi-GPU systems. Focused on stabilizing cross-GPU buffer sharing, the developer used C++ and low-level GPU programming techniques to debug and resolve the allocator issue. The solution involved validating the fix across various hardware topologies and collaborating with the ROCm driver team to ensure robust integration. By enabling dmabuf export across all GPUs, the work improved buffer management and scalability for complex configurations, demonstrating strong skills in memory management and attention to runtime reliability in heterogeneous computing environments.
