Second Adept White Paper Published

The Adept consortium are delighted to announce the publication of the second Adept White Paper, "Evaluating Power Usage of Hardware Platforms". 

This White Paper follows on from the first Adept White Paper and describes the work undertaken on the project to characterise and understand power usage on a number of different hardware platforms, using the Adept Power Measurement System.

EMiT: Emerging Technologies Conference

Dr Michele Weiland, leader of the Adept project, will be giving a keynote at the EMiT Conference in Barcelona on Friday, 3rd June 2016.

"Efficient HPC: Waste Not, Want Not"

The focus of the HPC community is firmly on reaching its next big goal: the Exascale. There are many technical hurdles that need to be overcome to reach this goal in the next five to ten years, but there is an underlying theme of efficiency. HPC applications often only use a few percent of the peak performance a system can offer, wasting vast amounts of resources that could be exploited to achieve increased science throughput. The efficiency of Exascale systems in terms of power is also of great concern – we will need to achieve 50 GFlop/s per Watt if we want to stay within a 20MW power envelope. In this talk, I will present the work of two projects: Adept, which investigates and models power/energy expenditure in parallel systems; and NEXTGenIO, which exploits Intel 3D XPoint technology to eliminate the I/O bottleneck in large-scale parallel systems.

Intel Xeon Phi User Group Conference: IXPUG

Adept was presented at the IXPUG/EMEA Conference in Ostrava, Czech Republic. The conference ran from 14-18 March 2016 and Adept was presented by EPCC's Emmanouil Farsarakis on Wednesday, March 16th at 16:00.

This talk concerned the work that Adept has undertaken in developing its power management tools, and also about using the RAPL tool for Intel processors.

If you would like to watch the talk, you can do so via IXPUG's recorded stream of the event here; the Adept talk begins at 07:11:00.

Slides from the talk will also be available shortly. 

 

Publication Round-Up

2015 was a very busy year for Adept! It was the second full year of the project and we authored a number of articles, presentations and talks during the course of the year.

Adept White Paper Published

The Adept Project consortium has published a White Paper detailing some of the advances the project has made. The White Paper was published in November 2015.

This White Paper concerns the Adept Benchmark Suite, which allows the measurement of power consumption and performance. There are a series of benchmarks, from small 'nano' benchmarks up to full application benchmarks.

Adept at SC15!

Adept is at SC15 in Austin, Texas, from the 15th to 19th November 2015.

We're at the EPCC booth #2503, so please stop by to see our new videos, pick up a copy of our white paper on benchmarking for power usage characterisation or simply chat to us about what we do!

Adept Benchmarks released!

We have now released the first version of the Adept Benchmarks for power and performance measurement. You can download them from EPCC's GitHub repository.

If you have suggestions for improvements, or spot any mistakes, please let us know by creating an 'issue' and we will do our best to follow up promptly!

Adept in Scientific Computing World

The Adept project has been discussed in a Scientific Computing World article- Software softens energy demands. You can read the full article at: http://www.scientific-computing.com/features/feature.php?feature_id=461

Teaser from the article:

"But in order to reduce power consumption, it must first be measured. In the Adept project, energy measurement is EPCC’s role –developing the benchmarks -- while Alpha Data is providing the power measurement board that filters data so as to get the highest resolution power reading. According to Johnson, EPCC has a set of different types of hardware in the laboratory so that it can test performance on different architectures and then provide feedback on the accuracy of the model’s predictions as compared to the actual energy consumption."

Adept Measurement System Introduction

The Adept project has published a video which is an introduction to instrumenting a computer for power measurement with the Adept measurement system. Please watch to learn more:

Presentation: Energy Efficient Parallel Software for Radio Access Networks

Adept team member Erik Berg recently presented at the SICS Software Week. His talk was titled ‘Energy Efficient Parallel Software for Radio Access Networks’. You can view the talk in the video below:



Abstract: The increasing number of radio base stations for mobile communication emphasizes the need for improved energy efficiency. Better alignment of the hardware and software properties is one way to reduce energy consumption. Another approach is to design scalable software that enables powering down idle devices. This presentation will highlight some of the research activities at Ericsson targeting this increasingly important area, including the EU FP7 Adept project. The Adept project develops models and tools to predict the power consumption and performance of parallel systems.
