The recognition of human activities in a smart home is an essential prerequisite in order to derive typical behaviors and needs of the inhabitants and adapt the functions of the smart home to them. Different sensor modalities, such as video or audio data in combination with machine learning methods can be used for this purpose. However, the use of video and audio data is associated with a strong infringement on the privacy of the inhabitants. In this paper, we present an alternative approach that uses vibrational data that is acquired by stationary wall-mounted sensors to detect a specific set of inhabitant activities using machine learning. We compare different neural-network based time series classifiers and show that is possible to detect the selected activities with up to 95% accuracy.

This paper presents a framework for defining, performing, and analyzing distributed load testing experiments for benchmarking edge-cloud clusters. This end-to-end workflow helps researchers build reproducible environments to evaluate cluster management techniques. Our implementation extends the open source tool Galileo by adding support for distributed execution on Kubernetes clusters, additional system monitoring instruments, as well as out-of-the box experiment workloads. We focus on providing tools that run across popular CPU architectures and provide a set of representative workloads, such as edge AI functions. We demonstrate our framework's capabilities in a set of experiments based on use cases commonly found in edge computingsystems research. Additionally, we show that the resource usage of our system is minimal and that it can run on resource-constrained devices.

In this paper, we present a framework for moving compute and data between processing elements in a distributed heterogeneous system. The implementation of the framework is based on the LLVM compiler toolchain combined with the UCX communication framework. The framework can generate binary machine code or LLVM bitcode for multiple CPU architectures and move the code to remote machines while dynamically optimizing and linking the code on the target platform. The remotely injected code can recursively propagate itself to other remote machines or generate new code. The goal of this paper is threefold: (a) to present an architecture and implementation of the framework that provides essential infrastructure to program a new class of disaggregated systems wherein heterogeneous programming elements such as compute nodes and data processing units (DPUs) are distributed across the system, (b) to demonstrate how the framework can be integrated with modern, high-level programming languages such as Julia, and (c) to demonstrate and evaluate a new class of eXtended Remote Direct Memory Access (X-RDMA) communication operations that are enabled by this framework. To evaluate the capabilities of the framework, we used a cluster with Fujitsu CPUs and heterogeneous cluster with Intel CPUs and BlueField-2 DPUs interconnected using high-performance RDMA fabric. We demonstrated an X-RDMA pointer chase application that outperforms an RDMA GET-based implementation by 70% and is as fast as Active Messages, but does not require function predeployment on remote platforms.
Graph-based approximate nearest neighbor algorithms have shown high performance and quality. However, such approaches require a large amount of memory and still take a long time to construct high-quality nearest neigh...

As humans, things, software and AI continue to become the entangled fabric of distributedsystems, systems engineers and researchers are facing novel challenges. In this talk, we analyze the role of IoT, Edge, and Cloud, as well as AI in the co-evolution of distributedsystems for the new decade. We identify challenges and discuss a roadmap that these new distributedsystems have to address. We take a closer look at how a cyber-physical fabric will be complemented by AI operationalization to enable seamless end-to-end distributedsystems.
