Jens Breitbart

Research summary

I got my Ph.D. for my research on programming models for future HPC systems. My research has been centered around easing parallel programming mostly with a focus on programming models and high performance computing. I am currently a software architect in the area of driver assistance and automated driving.

Projects

Field Data Collection

Bosch Driver Experience • 2021 — Present

Most modern algorithms require a lot of specific data during its development phase. This data is intended to be collected in the field by cars that are driven by end-customers and upload it to online storage for further processing.

Automated Driving for Commercial Vehicles

Bosch Automated Driving • 2018 — 2021

Under NDA.

HermitCore

Research interest • 2015 — Present

HermitCore is a novel unikernel operating system targeting a scalable and predictable runtime behavior for HPC and cloud environments. It extends the multi-kernel approach and combines it with unikernel features.

Front Facing Driver Assistance Camera for Trucks

Bosch Driver Assistance • 2016 — 2018

Adopt the existing multipurpose camera for cars to work well with Daimler trucks and other similar comercial vehicles. It provides semi-automated driving (Level 2) functions like lane keeping and object and pedestrian detection.

PSAM: Partitioned Single Assignment Memory

Research interest • 2011 — 2016

PSAM is an experimental PGAS implementation designed to provide allow fine-grained synchronization and efficient remote memory caching mechanism.

FaST: Find a Suitable Topology for Exascale Applications
