R. Andreoli, T. Cucinotta. "DistWalk: a Distributed Workload Emulator," (to appear) in Proceedings of the 25th IEEE international Symposium on Cluster, Cloud and Internet Computing (IEEE CCGRID 2025), May 19-22, 2025, Tromsø, Norway.
This paper introduces DistWalk, a flexible, distributed, scalable, and open-source toolkit designed to emulate compute, network, and storage workloads across a networked infrastructure, and measure the resulting end-to-end latency. DistWalk provides fine-grained control over the workload behavior, which consists of a graph-like sequence of operations spanning multiple servers, It supports several communication protocols and traffic patterns, and enables the customization of several factors, such as the duration and parallelism of compute-intensive operations, and the I/O data access and synchronization mode, among others.
The proposed toolkit may be used to experiment with a variety of deployment models, from bare-metal to virtualized or containerized environments, e.g., using Cloud/Edge infrastructures, OpenStack, Kubernetes, or other orchestrators, allowing for experimental comparisons of the achievable latency across a wide range of system-level configurations.
