XtreemOS at SuperComputing 2009

XtreemOS exhibited for the 3rd time this year at Supercomputing '09 in Portland, Oregon. Sharing the booth were consortium partners INRIA, CNR, VUA, ZIB and Kerlabs.

During the show, the new version 2.0 of XtreemOS was demoed (along with the latest version of Kerrighed using their cluster in a box). Interest from visitors ranged from university faculty interested in integrating XtreemOS in their teaching to other research institutions wishing to join future development.



Despite the economic crisis, there were not many signs of retrenchment in investment or research in HPC (high performance computing). A number of ambitious future projects were unveiled at Supercomputing, along with record numbers of visitors.

One other highlight from the show was the keynote from former U.S. Vice President AL Gore, who addressed the topic of how supercomputing can be used to harness solutions to global climate change science.

Already, space for SC '10 is nearly sold out, which portends another record breaking exhibition.


XtreemOS at Poslovna Linux Konferenca

Poslovna Linux konferenca (Business Linux Conference) is an annual event in Slovenia, focussing on the use of Linux and other open-source software in business environments.  This year  the conference took place in Portorož on the 28th and 29th of September.



XtreemOS was presented by Marjan Šterk and Matej Artač (both from XLAB) as a platform for collaboration both within companies and across company borders. A potential use case in an architectural bureau was used to enumerate the most important features of XtreemOS in businesses: sharing files with XtreemFS, exploiting grid resources for automatic compilation of project documentation, marketing material, animations etc, and use of applications installed on remote computers without the need for local user accounts. A simplified live demonstration of these features was also shown.


Feedback: XtreemOS summit at Euro-Par 2009

Delft, The Netherlands - August 25, 2009

The first XtreemOS summit was co-located with Euro-Par 2009 in Delft, The Netherlands.


The objective of this half-day summit was to present the XtreemOS technology with different talks ranging from a general overview to selected topics including security, resource matching, and parallel I/O. After the talks different demonstrations were run to show the benefits of  the XtreemOS system.

The summit concluded with an interesting and fruitful discussion between the audience and the XtreemOS representatives.

Thilo Kielmann (VUA) also gave an invited talk at CoreGRID 2009 workshop (in conjunction with EuroPar): "XtreemOS a sound foundation for IaaS and cloud federations"

In addition, John Mehnert-Spahn (UDUS) presented an XtreemOS paper:

- "The Architecture of the XtreemOS Grid Checkpointing Service" by John Mehnert-Spahn, Thomas Ropars, Michael Schoettner and Christine Morin



XtreemOS at Libre Software Meeting (RMLL'09)

Rencontres Mondiales du Logiciel Libre 2009 in Nantes, France

In 2009, LSM took place between July 7th and July 11th in Nantes, France ! An event managed by the Linux-Nantes Association, with active support from Free, Libre and Open Source Software users’ associations from the whole country.

On July 8th 2009, Surbhi Chitre of INRIA, Rennes gave a talk at RMLL'09 Nantes on OpenVZ integration in XtreemOS. She explained the need of XtreemOS, its importance as a solution to make grids easy and also the features that XtreemOS offered along with why and how it was new.

She illustrated her design of OpenVZ integration in XtreemOS, the difficulties in doing so and why OpenVZ was chosen for integration in XtreemOS.

Surbhi's presentation slides are available here.

XtreemOS at ISC'09

International Supercomputing Conference

The International Supercomputing Conference (ISC) is Europe’s leading Conference and Exhibition on High Performance Computing, Networking and Storage. The 2009 event took place in Hamburg, Germany, last June 23-26, 2009.

XtreemOS had a booth at ISC'09 showing the current software prototype (version 2.0 rc1) including demonstrations of the XtreemOS grid checkpointing service.

ISC’09-2 ISC’09-1

 Furthermore, the Wissenheim application (a multi-user virtual world) was also presented running on top of the XtreemOS Object Sharing Service (OSS) in charge of distribution and consistency management of the scene graph.

ISC'09 had 36 sponsors, 120 exhibitors and 1,670 attendees.

XtreemOS keynote talk at BNCOD 2009

Filed Under:

Domenico Laforenza (CNR) will give a keynote talk about XtreemOS at the 26th British National Conference on Databases (BNCOD 2009) to be held at Birmingham University from the 7th to 9th of July 2009.

The theme of BNCOD 2009 will be "Dataspace: the Final Frontier". Dataspace is a term recently coined to denote the expansion of the database topic into the broader area of managing large numbers of diverse but interrelated data sources of many varying forms.

D.Laforenza's talk is entitled "XtreemOS: Towards a Grid-enabled Linux-based Operating System" and present XtreemOS, as a first European step towards the creation of a true open source operating system for Grid platforms.
