TechSocial June 2026 Tue, June 9, 2026

In association with KQCodes, ARC proudly presents the TechSocial Series. In June, we will be joined by Jascha Achterberg, Co-founder of Callosum to talk about - The algorithms, orchestration, and systems-level design of heterogeneous computing systems for large-scale AI.

A series of FREE, informal TALKS, DISCUSSION and PIZZA! Open to anyone interested in computational research methods, technology and innovation, this series covers a broad range of tools, programs, digital environments & language.

Join us every month at 90 High Holborn

Abstract

At Callosum we are working on how heterogeneous computing systems made up of multitudes of different accelerator types can be used to run large scale AI more efficiently than when using commonly built homogeneous computing systems. This presentation will cover the results we have from our existing multi-cloud deployment software system that achieves the processor heterogeneity by orchestrating workloads across multiple clouds by identifying and deploying novel disaggregation patterns for large scale AI. As the latency of multi-cloud deployments naturally can be prohibitive for advanced heterogeneous deployment, we will also cover the heterogeneous cluster we are in the process of constructing, which will allow for even more complex and optimised deployment strategies. With this presentation we hope to start an active collaboration with the Advanced Research Computing Centre on heterogeneous computing systems for AI and scientific workloads deployed at UCL.
