Enabling unstructured-mesh computation on massively tiled AI processors: An example of accelerating in silico cardiac simulation Open
A new trend in processor architecture design is the packaging of thousands of small processor cores into a single device, where there is no device-level shared memory but each core has its own local memory. Thus, both the work and data of …
The connectivity network underlying the German’s Twittersphere: a testbed for investigating information spreading phenomena Open
Online social networks are ubiquitous, have billions of users, and produce large amounts of data. While platforms like Reddit are based on a forum-like organization where users gather around topics, Facebook and Twitter implement a concept…
iPUG for Multiple Graphcore IPUs: Optimizing Performance and Scalability of Parallel Breadth-First Search Open
This research delves into the potential of Graphcore's IPU AI-optimized architecture in the realm of High-Performance Computing (HPC). Focusing on solving complex challenges like sparse systems and irregular applications, the dissertation …
BeFaaS: An Application-Centric Benchmarking Framework for FaaS Platforms Open
Following the increasing interest and adoption of FaaS systems, benchmarking frameworks for determining non-functional properties have also emerged. While existing (microbenchmark) frameworks only evaluate single aspects of FaaS platforms,…
