New Adept Project Paper: Benchmarking for power consumption monitoring

Researchers from the Adept project will present a paper at the  International Conference on Energy-Aware High Performance Computing (EnA-HPC). This paper, on benchmarking for power consumption monitoring, has just been published in the Journal of Computer Science - Research and Development.  You can access the paper here:

Here is a brief abstract of the paper:

This paper presents a set of benchmarks that are designed to measure power consumption in parallel systems. The benchmarks range from low-level, single instructions or operations, to small kernels. In addition to describing the motivation behind developing the benchmarks and the design principles that were followed, the paper also introduces a metric to quantify the power-performance of a parallel system. Initial results are presented and help to illustrate the contribution of the paper.

Adept Podcast with HPC Wire

We're very pleased to announce that Adept has recently featured in a podcast hosted by HPC Wire. 

'The Adept Merging of HPC and Embedded Computing' podcast features EPCC Applications Consultant Nick Johnson as he discusses the Adpet project which aims to merge the worlds of HPC and embedded computing to address the needs of efficient computing.

Also available on iTunes, Nick's interview can be listened to on the HPC website here.

The workshop was very well attended and we hope that everyone attending found it both interesting and informative. 

Adept Workshop: Efficient Modelling of Parallel Computer Systems

Workshop held in conjunction with HiPEAC 2014, 21st January 2014, Vienna (Austria)

Adept addresses the challenge of energy‐efficient use of parallel technologies. We build on the expertise of software developers from high‐performance computing (HPC) to exploit parallelism for performance, and on the expertise of embedded systems engineers in managing energy usage. The aim of Adept is to develop tools and methodologies that will guide software developers and help them to model and predict performance and power consumption of parallel software and hardware.

In line with the project goals this workshop will bring together experts from the HPC and embedded domains to discuss the current state‐of‐the‐art and research in the area of performance and power modelling and monitoring of parallel computer systems. Specific emphasis will also be given to the cross‐fertilisation of expertise between the two domains.

Adept Initial Press Release

Adept project investigates energy efficiency in parallel technologies

Edinburgh, 11th October 2013 – Today, a consortium led by EPCC, the supercomputing centre at the University of Edinburgh, announced the successful launch of the Adept project.  Adept brings together software and hardware experts from HPC and Embedded to address the challenge of energy efficient use of parallel technologies. In addition to EPCC, the consortium comprises two world-leading Universities, Uppsala and Ghent, as well as two representatives from industry, Alpha Data Parallel Systems Ltd and Ericsson AB.  Adept is supported with €2.8m through the European Commission’s Framework 7 programme.

The challenge

It's been quite some time since parallel computing was limited to only high-end scientific applications; it is increasingly becoming ubiquitous in all forms of software development and especially so in the Embedded domain.  In HPC, the race towards reaching the exascale by 2022 is steering research into new directions, one of which is that of energy efficiency.

Dr Michèle Weiland, the coordinator of the Adept project which is led by EPCC, explains: “We will address the challenge of energy efficiency in parallel technologies by building on the expertise of HPC software developers in exploiting parallelism for performance, and Embedded Systems engineers in managing power consumption”.

The objectives

The aim of Adept is to further the understanding of the power usage of parallel software and hardware, and to develop a tool that enables the rapid exploration of power consumption and performance design space across a range of heterogeneous architectures.

“Over the last 15 years, one of our overriding research goals has been to produce new technologies and tools to help programmers understand and optimise their systems for better performance and power efficiency”, says Professor Erik Hagersten from Uppsala University. “This project brings us together with application experience from HPC and large-scale commercial Embedded computing, as well as some of the leading researchers in efficient performance modelling. This is an ideal environment for taking our research results to a new level”.

Professor Lieven Eeckhout from Ghent University, who is working on the modelling aspect of the project, agrees: “The Adept project is a great opportunity for me and my research group to combine the interval model, which we developed here in Ghent, with the cache models developed in Uppsala, and build a powerful tool for software developers to explore hardware options in the Embedded and HPC space”.

The view from industry

Alpha Data Parallel Systems Ltd, a leading global supplier of high-performance reconfigurable platforms, is one of the commercial partners in Adept.  Dr Andrew McCormick, Design Engineer at Alpha Data, explains why the project is important to the company: “Adept will help bring power management for HPC down from the cluster level to the individual application level. Identifying the total lifetime cost of power hotspots in applications may justify the extra development costs of using lower power customisable hardware accelerators. Alpha Data is pleased to be involved in this project, which could lead to new opportunities for the reconfigurable computing market".

Adept started on the 1st September 2013 and is set to run for 3 years. For more detailed information on the project please visit the website, www.adept-project.eu, or contact:
