PROFILE

Alexandre De Limas Santana

Alexandre Delima Santana developed a vector-length-agnostic JIT 1x1 convolution kernel for the oneapi-src/oneDNN repository, targeting RISC-V’s RVV architecture. His work focused on enabling portable, high-performance convolutional neural network operations across varying vector lengths, addressing the challenge of hardware diversity. Using C++ and leveraging expertise in JIT compilation and high-performance computing, Alexandre introduced new format tags and updated memory descriptor handling to ensure correct data layout and efficient memory access. These architectural improvements enhanced both scalability and maintainability of the kernel and memory model, providing a robust foundation for future development and broader RVV support within oneDNN.
