Scientists can now use both grids in their applications
BUDAPEST, Hungary, Dec. 7 -- The EELA-2 project has created a Bridge that connects the OurGrid middleware to gLite, the middleware that is also used by the large European EGEE Grid. This OurGrid-gLite Bridge is an implementation of the EDGeS 3G Bridge. Thanks to the new bridge, scientists in Latin America can now seamlessly submit jobs to both grids. When they do not have enough computing capacity on the gLite part of the EELA-2 e-infrastructure they can use the OurGrid resources.
OurGrid is a peer-to-peer based desktop grid middleware that is used to share computers amongst peers. Jobs can run on computers that have spare computing time. OurGrid takes care this is handled in a fair way, and computer owners always have access to the full capacity of their own system when needed.
OurGrid is widely used. Currently it connects about 1,000 computers of the Federal University of Campina Grande (UFCG) Institutional Grid in Brazil, which is part of the EELA-2 e-infrastructure. This complements the service part of the EELA-2 e-infrastructure that comprises over 3000 computers connected with gLite.
EELA-2 is a project to support the collaboration between scientists in Latin America and Europe by providing them with a shared computing infrastructure. Scientists all over Latin America and Europe use the EELA-2 e-infrastructure. There are over 60 applications that are running on EELA.
The EDGEeS 3G Bridge was already running, bridging between BOINC or XtremWeb based Desktop Grids and gLite based EGEE. This bridging created the largest computational infrastructure in Europe: It connected EGEE with about 150.000 processors, with several desktop grids (SZTAKI Desktop Grid, IberCivis, AlmereGrid, and several local desktop grids) with about 100.000 computers.
"The EELA-2 result shows the EDGeS Bridge design is sound enough for others to write plugins for. This is a big step towards seamless integration of different infrastructures into one pan-European computational grid," said Peter Kascuk, EDGeS project manager.
"Implementing the EDGeS 3G Bridge proved to be very easy. The new bridge will help our scientists with getting more computational resources for their applications when they need it", said Francisco Brasileiro, lead researcher of the OurGrid project and manager of the joint research activity of the EELA-2 project.
The EDGeS project is a European project with 9 partners and 7 subcontractors led by MTA SZTAKI. EDGeS is supported by a Grant from the European Commission's FP7 IST Capacities Programme under grant agreement RI-211727.
About OurGrid and EELA2
The EELA-2 e-infrastructure has a service part that runs gLite and an opportunistic part that runs OurGrid. A 3G bridge allows the interconnection of the two parts of the e-infrastructure. More information about the OurGrid middleware can be found at http://www.ourgrid.org/.
In a recent solicitation, the NSF laid out needs for furthering its scientific and engineering infrastructure with new tools to go beyond top performance, Having already delivered systems like Stampede and Blue Waters, they're turning an eye to solving data-intensive challenges. We spoke with the agency's Irene Qualters and Barry Schneider about..
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).
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...

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.
