Dec. 9 -- The use of computational grids, also known as grid computing, facilitates people's lives by combining computer resources from various domains for a common task. An EU-funded team of researchers has developed and launched its second Linux-based grid operating system. Under the motto "Making Grid Computing Easier," the XTREEMOS project has released the second version of its Linux-based grid operating system. XTREEMOS, which is scheduled to end in May 2010, has received over EUR 14 million in financial support.
Funded under the Information Society Technologies (IST) of the EU's Sixth Framework Programme (FP6), the XTREEMOS (Building and promoting a Linux-based operating system to support virtual organisation for next generation grids) project has designed and integrated a platform of open source technologies to facilitate usage, management, scalability and programming.
Due to end in May 2010 and coordinated by the France-based group Caisse des Dépôts et Consignation (CDC), XTREEMOS successfully provides new grid capabilities including simpler monitoring and job submission. It also offers virtual organisation management and a comprehensive security implementation.
According to the partners, XTREEMOS is available in three flavours: PC, XTREEMOS cluster, and XTREEMOS Mobile.
The PC flavour allows for aggregating standalone PCs (personal computers) as computation resources into XTREEMOS grids. The XTREEMOS cluster is based on Kerrighed's Linux SSL (single-system image) technology, which is a Linux cluster that enables users to obtain an image of a single large system. XTREEMOS Mobile enables XtreemOS services to be run on mobile devices including Nokia Internet Tablets.
The latest 2.0 release version includes several functionalities: (1) creation and management of dynamic virtual organisations, (2) application execution management, (3) XtreemFS, (4) XOSAGA programming interface, and (5) Xosautoconfig.
The first one focuses on security infrastructure ensuring the secure operation of the system, while the second allows searches for available nodes that meet the application needs of candidates, and then executes the application on the selected nodes. XtreemES enables installation scalability by adding machines with free storage resources, XOSAGA programming interface provides access to XTREEMOS resources and services, and Xosautoconfig supports grid administrators and other users in their efforts to deploy XTREEMOS nodes on virtual machines, grids and test beds quickly.
Interested users can download the second public version on XTREEMOS' Web site. The source code, sample applications and demos are also available online.
The XtreemOS partners are from China, France, Germany, Italy, the Netherlands, Slovenia, Spain and the UK.

The Xeon Phi coprocessor might be the new kid on the high performance block, but out of all first-rate kickers of the Intel tires, the Texas Advanced Computing Center (TACC) got the first real jab with its new top ten Stampede system.We talk with the center's Karl Schultz about the challenges of programming for Phi--but more specifically, the optimization...
Although Horst Simon was named Deputy Director of Lawrence Berkeley National Laboratory, he maintains his strong ties to the scientific computing community as an editor of the TOP500 list and as an invited speaker at conferences.
Supercomputing veteran, Bo Ewald, has been neck-deep in bleeding edge system development since his twelve-year stint at Cray Research back in the mid-1980s, which was followed by his tenure at large organizations like SGI and startups, including Scale Eight Corporation and Linux Networx. He has put his weight behind quantum company....

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.

For engineers looking to leverage high-performance computing, the accessibility of a cloud-based approach is a powerful draw, but there are costs that may not be readily apparent.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
