Grid5000:School2014

Grid5000 Spring School 2014

June 17-19, 2014 - Ecole Normale Supérieure de Lyon Organized by GIS G5K, Hemera and the ENS Lyon, LIP Laboratory with the financial support of Inria,

Introduction

After the successful 2006, 2009, 2010, 2011 and 2012 editions (respectively 100, 72, 80, 67 and 75 registered participants), Grid'5000 practitioners and future users are invited to gather, learn and share experience around the usage of Grid'5000 as a scientific instrument.

Hosted by Ecole Normale Supérieure, from June 17th to June 19th 2014, this 6th edition of the Grid'5000 school will bring together, but is not limited to, Grid'5000's newbies as well as expert-users, technical team and executive committee for 3 days of keynotes, talks and practical sessions focusing on best-practices and results. Presentations and practical sessions will cover basic and advanced usages of the platform as well as lessons on experiment control at large-scale. A challenge contest to showcase tools and environments demonstrating the deployment of distributed systems on Grid'5000 (including large-scale middleware, parallel and cloud applications, etc.) will be held this year for the third time. Language for the school will be English.

Thursday 19th June

9:00-9:45 : Introduction to Grid'5000 - feature overview by David Margery

Abstract : In the presentation, we will shortly motivate why Grid'5000 was built, and describe the type of experiment lifecycle it supports. Resource discovery, resource provisionning, and configuration will be covered for the different types of resources supported by the instrument : computes, data blocks, IPs, VLANs.

9:45-10:00 : break

10:00-11:00 : Keynote : André Brinkmann (Johannes Gutenberg-Universität Mainz, Germany) : How do I tell it to my hardware?

Abstract : Computer hardware and software are getting more and more complex, making application development a challenging task. One way to reduce the development efforts is to abstract from the underlying IT infrastructure by using multi-tier architectures, high-level languages and programming frameworks. Unfortunately, this approach hides opportunities to optimize accesses to the underlying hardware, which often leads to poor scalability. The talk includes techniques to pass semantic information from the application through different software layers down to the hardware, so that low-level software layers can use application knowledge to adapt to changing environments; examples will be given from the areas of high performance computing and Cloud computing.

11:00-13:00 : Presentation from G5K users (4 slots) - Session "Environments and Energy"

• Matthieu Simonin, Eugen Feller, Anne-Cécile Orgerie, Yvon Jégou, David Margery and Christine Morin : "snooze : evaluation of the self-healing and self configuration mechanisms"

13:00 - 14:00 : Lunch

14:00-15:30 : Selected talks from G5K Community

• Grid'5000 for high-quality reproducible research by Lucas Nussbaum

Abstract : There is currently a push towards higher-quality and more reproducible experimental research. The specific features of HPC and Clouds research make it a field where those questions are particularly important. In this talk, we will highlight some challenges faced in HPC and Clouds research, and describe how Grid'5000 already addresses many of them. We will also discuss some future plans and remaining open questions.

• Grid’5000 - Beyond Grids and Clouds by Adrien Lèbre

Abstract : Although HPC has been the primary focus of Grid’5000, the infrastructure has continuously evolved to address additional concerns such as server virtualisation, cloud, and more recently energy concerns. To illustrate such evolutions, we will present few cloud experiments that have been conducted on top of the platform and discuss how the use of advanced toolkits made them possible. We will conclude the presentation by raising current challenges about network virtualization and big data the Grid’5000 community is facing and the first technical solutions the technical board has provided.

• EE@G5K by Laurent Lefèvre

Abstract : This talk will cover recent works dealing with energy efficiency and energy reduction and benefiting from the Green Grid5000 infrastructure.

15:30-16:00 : Conclusion / Awards (best presentation, best challenge) / End of G5K Spring School

Call for presentations and practical sessions

Important dates

• April 7, 2014 (deadline extended): full-submission deadline for presentation and practical sessions proposals
• April 30th, 2014: notification to authors
• June 6th, 2014: Registration to the Grid'5000 Large Scale Deployment Challenge.

Call for presentations

Grid'5000 users are invited to present recent results (including already published results) obtained using Grid'5000 as well as the tools and techniques used to produce these results. They will be evaluated based on:

• their scientific contribution,
• the quality of their experimental process
• the potential for other users to reproduce those experiments and/or to learn from those experiments for their own problems
  • availability and visibility of the environments and scripts used, or
  • clear description of the techniques used

The presentations will last 30mn and will have a fixed format with

• 15mn to describe the scientific results
• 5 to 10mn to present techniques used to conduct the experiments
• 10 to 5mn for questions.

Submissions in the Springer LNCS style should be either:

• 1 to 2 pages document (i.e a short paper) focusing on Grid'5000 usage and referencing a recently published or submitted paper describing the work. Please send a pre-print of this document to help assess the interest of the work for presentation to the Grid'5000 school. This pre-print will not be made public.
• 4 to 6 pages, presenting work in progress

Submissions will be handled through Easychair system : https://www.easychair.org/conferences/?conf=g5kss14

Call for practical sessions

Seasoned Grid'5000 users are invited to submit proposals for practical sessions. These practical sessions should be focused on dedicated kadeploy environments maintained by the submitters or on specific tools developed or used to ease the use of Grid'5000 (e.g. on common use-cases of the instrument). In particular, maintainers of Glite, Condor or cloud management stack (to name a few) are invited to make their work known. Practical sessions should be 1,5h or 2h long, or combine 2 sessions. Authors are invited to submit a 2 page long proposal detailing the tool, environment or technique that will be taught to practitioners, as well as the main steps of the practical session. Submissions will be handled through Easychair system : https://www.easychair.org/conferences/?conf=g5kss14

Registration for the Grid'5000 Large Scale Deployment Challenge

A challenge will be organized during the upcoming Grid'5000 School 2014, and we encourage users to submit a demo of your Grid'5000 experiment. Submission about all acceptable uses of Grid'5000 are welcomed: experiments on networking, virtualization, operating system, runtime, middleware, libraries, programming models, emulation, simulation, applications ... It is a great opportunity to demonstrate your work, your tools, and your mastering of the Grid'5000 platform. A submission consists in a short document (1 to 4 pages in the Springer LNCS style) describing the scientific context of the experiment, and giving an overview of the experiment. Submissions will be handled through Easychair system : https://www.easychair.org/conferences/?conf=g5kss14 A few submissions will then be selected by the jury (composed of members of the Grid'5000 steering committee), and selected candidates will get the chance to do a live demo during the Grid'5000 School (the full experiment is expected to take between 30 minutes and 1 hour). Prizes will be awarded based on (in no particular order):

• size of the experiment (number of cores/nodes/clusters/sites and percentage of used resources: network, CPU, RAM, disks)
• complexity of the experiment
• efficiency of the experiment (qualitative ratio between quality of results and used resources)
• use of Grid'5000 features: Kadeploy, the Grid'5000 API, KaVLAN ...
• reproducibility: is your experiment fully scripted? Does it involve some manual steps?
• quality of the experimental process and methodology
• interest of the experiment for the Grid'5000 community
• quality of the live demo

Candidates can group themselves in teams. However, only one prize per team will be given. There is no restriction on the status of participants: interns, PhD students, engineers, permanent staff are all welcomed. However, when deciding the attribution of prizes, the status of participants might be taken into account.
