Talk on zero-waste computing, Wednesday 13th Sept 2pm
Claire Antel
Dear reco & software trigger folk,
We’d like to invite you to a talk on zero-waste computing
in the context of HEP reconstruction by Ana-Lucia Varbanescu
(University of Twente) and Stephen Swatman (University of
Amsterdam/CERN), on Wednesday 13th September at 2pm CEST
https://indico.cern.ch/event/1320368/
This will be an interesting talk/light tutorial on how computing resource waste can happen and how to avoid it. The outline is as follows:
“Towards Zero-Waste Computing with Performance Engineering”
Many new applications emerge in need of high-performance computing resources. However, they are not always ready to use such resources efficiently. As a result, we observe significant resource waste when such applications are deployed on real heterogeneously, potentially distributed hardware. To avoid such waste in computing, performance engineering methods and tools can be used to identify performance bounds and bottlenecks at application and system level. In this tutorial, we present an introduction (with examples) in performance engineering methods and tools.
In order to put these ideas into practice, we briefly consider a connected component labeling problem from a track reconstruction application implemented for GPGPUs. Through this example, we aim to show how naive implementations of algorithms can lead to wasteful usage of hardware resources, and how profiling tools and models can guide us to implementing zero-waste applications."
The presentation will happen on zoom only. Connection details can be found in the indico link.
Hope to see you there,
Christina (LHCb), Claire (ATLAS) & Giulia (Belle II) for the HSF reconstruction & software trigger forum
The HEP Software Foundation (HSF) facilitates coordination and common efforts in (HEP) software and computing internationally. In particular, the Reconstruction and Software (SW) Triggers Working Group
is a forum to foster collaboration and common solutions on design and
implementation challenges in event reconstruction and SW trigger topics.

A reminder: This talk is happening today at 2 pm CEST (in a little over an hour).
