PROFILE
Selvin Xavier
Selvin Xavier worked on performance and reliability improvements for the amzn/rdma-core repository, focusing on the BNXT_R data path. He developed a push buffer optimization that initializes buffers during QP creation and uses them directly in post_send, reducing CPU cycles and improving throughput for the first 15 queue pairs. Selvin also corrected inline size alignment to prevent failures in data transmission. In a separate effort, he fixed a pointer type casting issue in the low-latency push path, ensuring accurate data copying and data integrity. His work leveraged C, kernel development, and low-level programming to enhance driver efficiency and maintainability.
