Load imbalance is often a challenge for applications in parallel systems. Static cost models and pre-partitioning algorithms distribute the load at the beginning. Nevertheless, dynamic changes during execution or inaccurate cost indicators may lead to imbalance at runtime. Reactive work-stealing strategies can help monitor the execution and perform...

Social interactions increasingly shift to computer-mediated communication channels. Compared to face-to-face communication, their use suffers from a loss or distortion in the transmission of social signals, which are prerequisites of social interactions. Social virtual reality platforms offer users a variety of possibilities to express themselves v...

Recent advances in High-Level Synthesis (HLS) allow software developers to offload compute kernels to FPGAs without deep knowledge about low-level hardware description languages. However, this abstraction comes at the cost of control over the bitstream and thus complicates features like partial reconfiguration. We introduce a vendor-agnostic high-l...
