11:10 AM PIC Site Report Spring 2012

PIC is a scientific-technological center providing High Throughput and Data Processing Services to various scientific disciplines: High Energy Physics, Astrophysics, Cosmology and Life Sciences among others. To fulfill these communities requirements it needs to maintain a steep capacity growth while keeping high levels of reliability. Thanks to technology improvements, in the last years it has been possible to support this growth keeping the overall energy budget about constant. However, power limit is getting close and, as user communities and requirements just keep growing, energy efficiency has become a key metric to ensure the sustainability of the activity. Therefore, power efficiency has become the metric for most purchasing decisions. The current input power limitations are a 200KVA UPS line to our main computer room and 100KVA UPS line to an independent, more energy efficient, module (PUE 2.3 vs 1.55). While a significant improvement of the situation is on sight, as of today we have to hold out with the available power. That means that our resources are mostly channeled on “going green”: how to save as much energy as possible to keep our equipment running while still delivering the required service. With that in mind, different techniques are being experimented: improvements on racks to enhance cooling, by controlling air fluxes; newer, more efficient equipment that has a better performance unit per watt ratio; and virtualization technologies that allow us to consolidate servers. In this presentation a brief description of the experiments running at PIC will be given. Furthermore, the status of the PIC site will be presented: computing resources, storage resources, datacenter considerations and software considerations regarding the most resource-consuming project, LHC, as well as other projects, and will try to give some insight on the trade offs found.

2:00 PM EasyBuild: building software with ease.

EasyBuild is an open source build framework written in Python that enables you to install software in a repeatable and consistent way. EasyBuild was motivated by the need for a system that would allow us to build and install multiple versions of a software package, built with different tool-kits in an automated manner. This whilst a huge number of software packages require us to divert from the standard configure - make - make install.

Speaker: Jens Timmerman (U)

2:30 PM DB On Demand at CERN

This presentation gives an introduction to the Database On Demand service at CERN. The need to offer support based on different database systems is on the rise within our user community. For example, one use case includes certain applications certified for running with non-Oracle databases (e.g. MySQL). Additional use cases are based on the desire expressed by user groups in being able to easily deploy and maintain different DBMS systems for their internal applications development. DB On Demand will cover this need offering users an easy way to create and manage their databases through a system that is fully integrated with different CERN technologies.

Speaker: Daniel Gomez Blanco (CERN)

4:00 PM Experience with new Service Management at CERN

The CERN Service Management project was born to fulfil the need of a global, homogeneous, and efficient service organization for all services provided to the users. On February 2011 the project entered in operation including in a first step services of the IT and GS departments. The CERN Service Management infrastructure is based on ITIL best practises and it includes a single Service Desk, a Service Portal providing access to the service catalogue and a set of standard processes as the most significant elements of the project. The tool that has been chosen to support the project and to give a single entry point to both supporters and users is a commercial product: Service-Now. The infrastructure provided by this tool has been adapted to accommodate the structures and needs of the laboratory. This talk presents the status of the project after one year of operation including the user’s and supporter’s perspectives, volume of work after the first year of operation, and the status and plans for the tool. Future developments as the incoming Service Level Management procedures, new processes and facilities will also be discussed.

11:00 AM Agile Infrastructure at CERN: Introduction

Over the past decade, CERN-IT has successfully managed thousands of machines for specific services in the CERN computer centre, using dedicated home-grown tools for configuration, installation and monitoring. However, a more dynamic and flexible approach is needed in order to provide new services, reduce inefficiencies, address business continuity, and cope with a remote extension to the Tier-0 compute facility. The presentation will explain the motivation, and introduce the Agile Infrastructure project detailed in the subsequent presentations.

Speaker: Dr Helge Meinhard (CERN)

Slides 2012-04-24-AI-Introduction.pptx

11:15 AM Agile Infrastructure: Configuration and Operation Tools

Configuration Management is not new to CERN. For more than a decade, CERN has build its own Quattor based Configuration Management infrastructure which is currently used to manage the configuration of several thousands machines. Experience shows that our infrastructure has several limitations. Moreover, it will not scale to manage configuration of systems on a heavily virtualised computer centre which will be scattered within two distant sites. This talk unveils those limitations and describes the technical choices that have been made when designing a new Configuration Management infrastructure. An update on current status of its implementation is also provided

Speaker: Dr Helge Meinhard (CERN)

Slides 2012-04-24-AI-Config.pptx

11:40 AM Agile Infrastructure Monitoring

The Agile Infrastructure (AI) project will establish a flexible and dynamic management of CERN computer centre resources. From the infrastructure monitoring perspective the AI project is working towards a common monitoring architecture to allow accessing and correlating information about all computer centre resources. This new monitoring solution will simplify the sharing of monitoring data and promote complex monitoring analysis tasks. This talk will motivate the need for such architecture, explain the architecture building blocks, and present the selected technologies.

Speaker: Mr Pedro Manuel Rodrigues De Sousa Andrade (CERN)

Slides AI_Monitoring_HEPIXSpring2012.pdf AI_Monitoring_HEPIXSpring2012.pptx

12:05 PM Agile Infrastructure: IaaS

The Agile Infrastructure project leverages emerging OpenStack Cloud Computing framework and Puppet configuration tools to provide Infrastructure as a Service in a sustainable and scalable way, but also ensuring sufficient resource flexibility and availability. In this solution, different services will be connected and scheduled over the IaaS layer using the same entry point. Moreover, a common approach to organizing the resources used by each different service will be deployed to be able to correlate usage tracking, auditing, authorization, etc... for various reasons such as security, accounting and isolation. This presentation will give an overview, the current status of the Openstack IaaS implementation and future plans along with how this fits into the CERN computing model

4:05 PM Data Protection Technologies: What comes after RAID?

Increasing data volumes and demand for access impose serious challenges for data storage infrastructures. Risk of data corruption increases over time, increase of disc size leads to an unacceptably long recovery time in usual RAID configurations. Recently a new solution, erasure coding, has appeared in the Cloud. It is based on a mathematical construction and involves dividing the data into a large number of small segments which are then duplicated and spread over multiple locations and in some cases multiple IaaS providers. Erasure coding in combination with RAIN (Redundant Array of Inexpensive Nodes) allows significantly reduce overhead ensuring data redundancy similar to RAID and possibility of recovery from storage nodes failures. Several solutions implementing erasure coding are already available on the market.

Speaker: Dr Vladimir Sapunenko (INFN)

12:10 PM CHOS in Production -- Supporting Multiple Linux Environments on PDSF at NERSC

The CHOS[1] software package combines a Linux kernel module, a PAM module, and batch system integration to provide a mechanism for concurrently supporting multiple Linux environments on a single Linux system. This presentation gives an introduction to CHOS and details how NERSC has deployed this utility on the PDSF HPC system to meet the complex, and often conflicting, software environment requirements of multiple applications. The CHOS utility has been in continuous use on PDSF for over 8 years, and has proven to be a robust and simple approach to ensure optimal software environments for HENP workloads. [1] CHOS was written by Shane Canon of NERSC, and the code is available on GitHub[2]. The CHOS technology is explained in detail in the paper at [3].

3:00 PM ITIL and Business Continuity (Service Perspective)

Based on ITIL best practices, the support of the overall business continuity is ensured by managing and controlling the risks that could seriously affect the corresponding services. The identification of the risks and the provision of measures to mitigate or eliminate the threats in the system will play an important role in achieving the level of service required to ensure the business continuity. The CERN Service Management project is starting to put the basis towards a future risk management activity covering the services of the IT and GS departments. A formal approach will be defined to analyze the service assets, the threats and the vulnerabilities and to establish countermeasures towards the increase of the services reliability. This talk presents the ITIL principles of business continuity and risk management and it describes several practical cases applied to some of the most important IT and GS services.

It will focus on major architectural changes being put in place as well as describe how these are better fitting the power, cooling and space envelopes available in the CERN hosting facilities. The talk will underline how the simplification of these architecture tends to streamline the process of delivering computing capacity quicker to the physics community.

Speaker: Eric Bonfillou (CERN)

2:30 PM The HEPiX IPv6 Working Group

Since the Vancouver HEPiX meeting in Oct 2011, the IPv6 working group has been busy expanding its IPv6 testbed and testing data management over IPv6. Work has also started on the full survey of the IPv6 readiness of all WLCG applications, software and tools. This talk will present our experiences to date and plans for the future. A second talk by Francesco Prelz will give more details about the experiences on the distributed testbed.

2:50 PM The IPv6 reality check: what we learned so far on the IPv6 distributed testbed.

The outcome of the first, extremely basic application tests that were performed on the dual-stack testbed that was set up by the HEPix IPv6 group is reported. Running sustained file transfers and deploying the File Transfer Service (FTS) over a mesh of 'gridftp' servers provided enough real-life issues for a first reality check.

Speaker: Francesco Prelz (Sezione di Milano)

3:10 PM Federated Identity Management for HEP

A single Grid (X.509) identity certificate together with an attribute certificate from a Virtual Organisation can be used by an appropriately authorised HEP user anywhere in the world to access WLCG resources wherever they may be. There are however many other non-Grid distributed computing services that HEP users also need to access; webs, wikis, mail lists, document databases, agenda systems, and other collaboration tools to name just a few. Traditionally access to these services has to be fully managed by the hosting site and this results in the requirement to create and manage many many user accounts. This is very painful for both sites and users. This talk will present an overview of work being done both in the general research and education community and by WLCG, in collaboration with other scientific communities, to improve this situation.

4:30 PM Cyber Security - The Road We've Traveled and Modest Predictions

One of the first cyber incidents was caused by an insect (a moth, in fact). Ever since then, the lower life forms have been trying to disrupt the virtual landscapes we construct for our users. As our virtual environments have evolved to be more complex, these other life forms have always evolved sufficiently to find new cracks in our defenses. As we continue down the current path we are reminded of a quote attributed to Einstein, "Insanity: doing the same thing over and over again and expecting different results." Of course, he also said, "Only two things are infinite, the universe and human stupidity, and I'm not sure about the former." So, let's look at how we got here and see if we can use that to guide what we should do in the future.

10:00 AM Helix Nebula

In Europe the EIROForum are the 8 international organizations pursuing fundamental research in science and space exploration. In this context, CERN and several of the other organizations, including ESA and EMBL are forming a collaboration to engage with European industry in public-private partnerships to build a European Cloud infrastructure capable of supporting the missions of these organizations. As well as addressing the purely technical aspects, the collaboration will focus on issues of policy and privacy, particularly in the area of data. The goals of the work are to understand cost and service models, and to understand how the needs of the science organizations can be fulfilled by commercial compute and storage providers. This talk will discuss the complementary large scale flagship projects proposed by CERN, ESA, and EMBL, and how they will address the open questions that may eventually enable science to make large scale use of such commercial facilities.
