Rennes, France November 12, 2009 - The XtreemOS project has
released the second public
release of its Linux-based Grid operating system under the motto "Making
Grid Computing Easier".
The consortium has conceived and integrated a platform of open source
technologies to enable easier usage, management, scalabilty and
programming on top of Grid computing resources.
XtreemOS brings new capabilties to Grids, such as easing job submission
and monitoring, while providing a comprehensive security implementation
and virtual organization management. XtreemOS comes in three flavors:
The PC flavor makes it possible to aggregate standalone PCs as
computation resources into XtreemOS Grids. The XtreemOS cluster flavor
is based on Kerrighed's LinuxSSI (single system image) technology.
LinuxSSI is a Linux cluster providing users an image of a single large
system. The third flavor, XtreemOS Mobile has been tailored to run
XtreemOS services on mobile devices, such as Nokia Internet Tablets.
The 2.0 release version includes the following functionalities:
- Creation and management of dynamic virtual organizations
The security infrastructure includes a set of services that guarantee
the secure operation of the system, providing management of
credentials, permissions and resources.
- Application execution management AEM is able to search
available nodes that fulfill the application needs from within a large
number of candidates and then execute the application on the selected
nodes. AEM provides job and resource monitoring so that users can get a
Linux-like view of their applications. A new experimental feature in
this release is the ability to run interactive jobs such as graphical
applications unmodifed; harnessing the power of a Grid system. In
addition, there is a new graphical tool for editing and managing job
submissions. Lasty, grid checkpointing and job migration has been
integrated into this version.
- XtreemFS is a replicated and distributed object-based file
system. It allows scaling an installation by adding machines with free
storage resources. It offers striping of files over multiple storage
servers for high performance parallel access. Furthermore, it supports
automated mounting of home volumes.
- XOSAGA programming interface The XOSAGA API is built using
the Simple API for Grid Applications (SAGA) standard from the Open Grid
Forum (OGF). It provides access to XtreemOS resources and services.
- Xosautoconfig is a new tool included in the distribution,
which assists Grid administrators and other users to quickly deploy
XtreemOS nodes on Virtual Machines, Grids and test beds.
With this release, the XtreemOS consortium invites the participation of
external contributors and feedback. XtreemOS is open source and GPL/BSD
licensed. For more info please email: contact@xtreemos.eu There is a
lively developer channel on #xtreemos-dev on irc.freenode.net, as well.

About XtreemOS
Partially funded by the sixth framework programme (Contract FP6-033576)
of the European Commission, XtreemOS is a 4-year research project,
comprised of 19 academic and enterprise partners in Europe and China
that aims to develop a Linux based grid operating system to simplify
the usage, management and programming of grids.

------------------------------------------------------------------------
XtreemOS is a 4-year integrated project aiming at building and
promoting a Grid operating system based on Linux to underpin future
computing grids. The XtreemOS operating system provides for Grids what
a traditional operating system offers for a single computer:
abstraction from the hardware and secure resource sharing between
different users. The project is led by INRIA and involves 19 research
and industrial partners from Europe and China. More information on our
project website: http://www.xtreemos.eu/

Did You Know? netcat is a unix utility which reads and writes data across network connections, using TCP or UDP protocol. It's designed to be a reliable back-end tool that can be used directly or easily driven by other programs and scripts. At the same time, it's a feature-rich network debugging and exploration tool, since it can create almost any kind of connection you would need and has several interesting built-in capabilities. Netcat, or "nc" as the actual program is named, should have been supplied long ago as another one of those cryptic but standard Unix tools.
