Roger Shepherd will report on his progress with benchmarking other

Paolo Savini and Jeremy Bennett have recently re-run the Embench 0.5
benchmarks to obtain data for GCC 10.2 and a historical record of
performance for Arm on versions of Clang/LLVM. They will report results

5. Publicity
- ------------

Stefan Wallentowitz is putting together an interview style blog post
about Embench, based on interview responses from Dave Patterson and
Jeremy Bennett

A new version of a generic presentation on Embench will be circulated
at the meeting.

Ben Marshall has raised the question of a standard citation for
Embench. Currently he is using:

title={Embench: Open Benchmarks for Embedded Platforms},
author={David Patterson and Jeremy Bennett and Palmer Dabbelt, Cesare
Garlati and G. S. Madhusudan and Trevor Mudge},

He has asked if there is a better citation he should be using.

Jeremy Bennett is giving a keynote talk at the 3rd Workshop on RISC-V
Activities held by Edacentrum, Germany. The talk will be looking at
the RISC-V Software Ecosystem. The final part of the talk explores the
importance of benchmarking in developing that ecosystem.

- - talk abstract: https://www.edacentrum.de/risc-v-software-ecosystem

Jeremy Bennett is speaking at VSDOpen on 10 October, a conference for
students in India. Although the talk has quite a broad abstract, it
will use Embench as an example of the bridge between hardware and
software in open source.
