Deeksha Goplani developed robust unit test suites for the ROCm/rccl and ROCm/rocm-systems repositories, focusing on improving reliability and test coverage for NCCL and RCCL APIs. Using C++ and CUDA, Deeksha implemented tests that validated device association with communicators in both single- and multi-device scenarios, and introduced checks for invalid communicator handles to ensure predictable error handling. In addition, Deeksha enhanced the register functionality tests by covering multiple registration configurations and improving output clarity, which streamlined CI reporting and enabled safer refactoring. The work demonstrated depth in GPU programming and contributed to more maintainable and reliable codebases.
