Research on the intersection of Machine Learning, High-Performance Computing and Hardware
The Hardware and Artificial Intelligence (HAWAII) Lab (previously: Computing Systems Lab) at the Institute of Computer Engineering at Ruprecht-Karls University of Heidelberg is focussing on vertically integrated research (thus considering the complete computing system) that bridges demanding applications such as machine learning (ML), artificial intelligence (AI), high-performance computing (HPC) and data analytics (HPDA) with various forms of specialized computer hardware.
Today, research in computing systems is most concerned with specialized forms of computing in combination with seamless integration into existing systems. Specialized computing, for instance based on GPUs (as known for gaming) or FPGAs (field programmable gate arrays) or ASICs (not the shoe brand but “application-specific integrated circuits”), is motivated by diminishing returns from CMOS technology scaling and hard power constraints. Notably, for a given fixed power budget , energy efficiency defines performance:
As energy efficiency is usually improved by using specialized architectures (processor, memory, network), our research gears to bring future emerging technologies and architectures to demanding applications.
Particular research fields include
- Embedded Machine Learning includes bringing state-of-the-art DNNs to resource-constraint embedded devices, as well as embedding DNNs in the real-world, requiring a treatment of uncertainty
- Advanced hardware architecture and technology by understanding specialized forms such as GPU and FPGA accelerators, analog electrical and photonic processors, as well as resistive memory
To close the semantic gap in between demanding applications and various specializations of hardware, we are most concerned with creating abstractions, models, and associated tools that facilitate reasoning about various optimizations and decisions. Overall, this results in vertically integrated approaches to fast and efficient ML, HPC, and HPDA.

Invited talk on “Green Machine Learning by Accelerating Deep Neural Architectures” and “Bayesian Machines: Unlocking the Potential of Bayesian Neural Networks for Enhanced Uncertainty Reasoning” at the 1st Heidelberg-Chile Workshop on Scientific Computing, Santiago, Chile, March 25-28!
Invited talk on accelerating Bayesian Neural Networks at the workshop on “Synergies of Machine Learning and Numerics Workshop”, March 11-14, Osaka, Japan!
In collaboration with the Neuromorphic Quantumphotonics Group led by Wolfram Pernice, among other collaborators, we published an article about “Probabilistic photonic computing with chaotic light” in Nature Communications. As a Bayesian Machine, this approach substantially reduces the costs associated with Bayesian Neural Networks, hopefully paving a way to new approaches to learned uncertainties in machine learning.
