EDGI introduces new tools to submit thousands of jobs to the grid

At the EGI User Forum, held in Vilnius, Lithuania, the EDGI project successfully demonstrated the use of the new MetaJob feature, which enables user to submit jobs to the EDGI Desktop Grid through gLite using one single command. The new feature can be used to wrap or describe thousands of jobs into one single MetaJob.

“Desktop Grids are especially useful for applications like parameter sweeps where you have thousands and thousands of similar jobs,” explains Ad Emmen, from AlmereGrid. “MetaJob is a command line ‘script’ that helps an EGI user to create these jobs for his/her application, and submit them automatically through standard gLite interfaces.”

The efficiency of MetaJob was demonstrated with great success at the EDGI booth. During the day, the EDGI team submitted 10,000 jobs several times to show the EGI User Forum visitors how this can easily be processed by BOINC, without disrupting the gLite infrastructure.

For Jozsef Kovacs, from the MTA SZTAKI (the Computer and Automation Research Institute, Hungarian Academy of Sciences), MetaJob makes it easier to handle a high number of jobs. MetaJob also allows “to increase the scalability of the service grid to desktop grid bridging services deployed by the EDGI project by decreasing the load of the service grid components – for example gLite wms,” he adds.

From a technical point of view the solution is based on the well-known Service Cluster Grid to Desktop Grid bridge, where an extra MetaJob description file - containing the definition of a huge number of jobs - is attached to the job as input file. This MetaJob input file is recognised by the 3GBridge component, which then creates the jobs and inserts them into BOINC. This solution also works with XtremWeb on the Desktop Grid side or ARC on the Service/Cluster Grid side without any modification.

This work was performed in the framework of "Task JRA1.5: Solve Service/Cluster Grid to Desktop Grid bridge scalability issues" in the EDGI project.

"This successful EDGI demonstration clearly shows that Desktop Grids can be used effortlessly for scientific day-to-day calculations,” said Peter Kacsuk from the EDGI project. “The relevance of Desktop Grids for e-Science has been proven once and for all.”

EGI User Virtualisation Workshop

Virtualisation and cloud computing have demonstrated how new technologies can enable dynamic execution environments or on-demand elastic service deployment with new, clear cost measurements and business models. Today’s ICT policies and services that are tailored to the established e-Infrastructure user communities do not always meet the needs of newcomers. Now is the time for EGI to provide a more flexible, efficient e-Infrastructure to attract new users on a larger scale.

EGI is organising a dedicated workshop on User Virtualisation (12-13 May 2011, Amsterdam) to bring together three critical groups within the European production infrastructure – resource providers, end-users and technology providers. The workshop will address specific questions through a series of user specific presentations and topical breakouts and serves as a follow-up to a recently published report on the integration of clouds and virtualisation into EGI. A technical roadmap defining the EGI cloud profile is also currently underway.

The workshop will deliberately not spend time on technology related presentations or provide an introduction to cloud computing, as there have been plenty of recent activities in the area (e.g. DCI collaborative and SIENA roadmaps) as well as recently held events (e.g. Cloudscape-III).

Discussions will be focused on understanding if and how EGI should move towards providing an Infrastructure as a Service (IaaS) model to support data intensive science and if this service should be provided by federations of resource providers from the research community. Other key topics to be covered include what sort of use (consuming communities and use cases) would the research community make of such a capability and what are the major issues (e.g. technical, policy, governance, etc.) that need to be resolved for this use to happen.

The outcome of the meeting will be a set of critical observations that can be developed into a roadmap that will meet the growing need for virtualised resources from the European research communities.

Technical Forum 2011 to be held in September in Lyon

As a successful User Forum draws to a close, the next meeting is already becoming a reality.

Steven Newhouse, Director of EGI.eu, opened the call for participation for the EGI 2011 Technical Forum in Lyon (19-23 September 2011), during the closing plenary session of the User Forum in Vilnius. The Technical Forum will be organised by EGI.eu and the Institut des Grilles du CNRS, the French National Grid Initiative.

While the User Forum held this week focused on user communities, with an emphasis on new tools, new applications and user support services, the Technical Forum will review the community's plans and progress towards the adoption of a federated virtualised infrastructure for European researchers.

The Technical Forum, to be co-located with the OGF33 meeting and Grid 2011, ‘will be a great opportunity to learn more about the state of the art of e-Infrastructure in Europe, including standards development and the community’s long-term plans for offering cloud interfaces to our users,’ says Newhouse.

The call for participation is now officially open. The Technical Forum welcomes submissions on a wide variety of EGI-related topics.

The event will also feature an exhibition area open for organisations active within the EGI community (projects, NGIs, companies) to present their work. In addition, end-users, application and tool developers, operations staff and others are encouraged to participate by submitting abstracts for technical sessions, posters, demonstrations, training sessions and workshops.

User training workshops: Heavy User Communities leading the way

The EGI User Forum 2011 in Vilnius has a packed programme offering a diverse range of workshops, demonstrations, presentations and tutorials with a focus on end-user training. With more than twenty three workshops and tutorials on offer over four days, the EGI-InSPIRE Heavy User Communities (HUCs) shall be playing their part.

Here is an overview of the HUC training workshops:

SHIWA platform

The Life Sciences community will introduce the SHIWA platform, a multi-system workflow execution platform and interoperability solution, supporting Askalon, MOTEUR, P-GRADE and Triana workflows. Workflow environments shield the end-users from the details of the grid infrastructure. The examples used at this training event are taken from the Life Sciences domain, but the tools presented here have much wider applications and should be of interest to all user communities.

  • Location: Theta; Time 11-Apr-2011 @14:00; Duration 03h30'

Using a StratusLab cloud infrastructure

StratusLab open-source cloud distribution allows resource centres to expose their computing resources as an ‘Infrastructure as a Service’ (IaaS) type cloud.

This tutorial presents the main StratusLab features and how they can be used by system administrators and scientists alike. They will learn how StratusLab-based infrastructures can be integrated with the EGI, and how the cloud services complement grid services. Practical exercises will teach the participants how to launch virtual machines, customise their computing environment, share those environments, manage virtual disks, and define complete services.

Participants will be provided credentials to access a StratusLab cloud infrastructure and must bring a laptop with python (2.6+), java (1.6+), and an ssh client installed.

Earth Science Data Processing Tools and Applications

The Earth Science community has a rich and extensive repository of data stored outside EGI and access to this data during job execution is a mandatory requirement. The Earth Sciences community is also interested in using the OPeNDAP protocol and Hyrax Data Server. Hyrax offers many features that go beyond high-performance access to distributed datasets, such as an extensible component-based architecture, multiple data representations, static or dynamic THREDDS catalogues. Due to the many different technologies, data-centres, standards and pseudo-standards, however, it seems that no general solution can be found. This talk should be of interest to anyone interested in these or similar issues.

Shared Services Tools based on the Ganga job definition

Ganga is a user-targeted job management tool designed to provide a homogeneous environment for processing data on a variety of technology ‘back-ends’. Initially developed within the high-energy physics (HEP) domain, Ganga has been adopted by a wide variety of other user communities as their default analysis and task-management system. The modular nature of Ganga means that communities can easily, if desired, develop their own suite of tools independent of both the core code and those of other communities. This presentation will use case-studies to illustrate the ease with which non-LHC communities (for example medical research), have adopted Ganga as their chief job-submission tool.

Experiment Dashboard

The Experiment Dashboard applications for infrastructure monitoring are widely used by the LHC virtual organisations for the computing shifts and site commissioning activities. The LHC Experiment Dashboard consists of:

  • Site Usability Dashboard, which uses tailored VO tests within the existing Site Availability Monitoring (SAM) system;

  • Site Status Board, which allows VOs to construct customised monitoring views;

  • SiteView, a single point of entry for site administrators, to understand how their site is used by the LHC VOs and to detect potential problems and ensure effective site performance.

The Dashboard applications are essential LHC computing operations tools. However, they are generic and can be adapted for other community’s needs. The talk will give an overview the Dashboard applications, highlighting the possibility of exploiting these applications outside the LHC domain.

  • Location: Lambda; Time: 13-Apr-2011 @16:00; Duration: 01h30'

MPI Hands on training

The Message Passing Interface (MPI) standards and their implementations are currently the most prevalent frameworks on which parallel applications are built. A significant problem in exploiting MPI applications on the grid is the inherent nature of its heterogeneous environments. Different MPI implementations, system interconnects or job managers can be found at different resource centres. In order to run an application, the end-user needs some ‘a priori’ knowledge about the resources. MPI-Start offers a unique and stable interface to execute parallel applications at the gLite based grid sites. It aims to hide the differences and complexities of the heterogeneous systems that compose a grid infrastructure by providing a high-level abstract layer. This presentation introduces the basic concepts of MPI, together with a detailed description of MPI-Start and how to use it.

The tutorial is suitable to all users who wish to adapt their MPI-based applications for use on the grid using gLite.

Kepler

Kepler is a free and open source workflow engine used extensively by the FUSION community. It is designed to help scientists and developers to easily create, execute, share and reuse their models across the scientific and engineering domains. In particular, Kepler includes components that integrate with different middleware stacks (e.g. gLite or UNICORE). Kepler workflows can be decomposed into smaller parts, thus allowing complex tasks to be divided into much simpler ones. This feature provides workflow designers with ability to build re-usable, modular sub-workflows. These can be saved and applied to other workflow. This introductory tutorial should be of interest to all users keen to explore Kepler's powerful capabilities. It will begin by showing how to use Kepler to build basic workflows; use relation paths and synchronisation; and to create control structures such as "if-else" and loops. Finally, job submission, monitoring, and data management shall complete the tutorial.
