Researching Automatic Performance Optimizations for Artificial Intelligence, Scientific and High Performance Computing

About me

I am Nicolas Weber, research engineer in the Intelligent Software Systems Group at the NEC Laboratories Europe. Before, I was PhD student in the Graphics, Capture and Massively Parallel Computing Group at TU Darmstadt supervised by Prof. Michael Goesele and Associate of the Graduate School of Computational Engineering at TU Darmstadt.

My main research interests are the automated optimization of code running on accelerator hardware, especially for Scientific and High Performance Computing, Biomedical and Artificial Intelligence applications. During my PhD I developed MATOG, an automated tool that automatically chooses optimal memory access patterns in CUDA applications. Since I joined NEC Labs I mainly worked on the SOL project. SOL is a compiler for neural networks running in PyTorch, TensorFlow or ONNX. It has many similarities with TVM, but in contrast mainly focusses on training, therefore provides it’s own AutoGrad implementation and much tighter integration into the executing frameworks.

Aside of SOL, I’m heavily involved in the development of the hybrid programming API VEDA for the NEC SX-Aurora TSUBASA and related libraries for integrating the SX-Aurora into PyTorch and TensorFlow.
