Agreement between PSNC and EGI.eu [1 November 2012]

Poznan Supercomputing and Networking Centre has signed  an agreement with the  EGI.eu to integrate the QosCosGrid middleware stack into the European Grid Infrastructure (EGI). QosCosGrid will extend the current capabilities of the EGI e-infrastructure by providing mechanisms for advance reservation and co-allocation of heterogeneous resources.

QCG-Broker 2.8 [5 September 2012]

After 6 months from the last release of QCG-Broker, the next version of the service has been deployed in the PL-Grid infrastructure. Main enhancements include: improved stability, improved performance, more accurate brokering algorithms and implemented support for interactive jobs.

QCG-Icon 1.0 Beta [5 September 2012]

The beta version of the lightweight desktop application enabling remote access to QosCosGrid has been already published. The 1.0 release of QCG-Icon provides many enhancements, but in its current version, may include minor bugs. All comments are welcomed as they help to improve the tool.

Cluster Inula in QCG [20 August 2012]

QosCosGrid has been extended with a cluster Inula from PSNC. Thus the QosCosGrid infrastructure offers currently access to 6 PL-Grid clusters.

QCG services update [3 August 2012]

The 2.6 release of the all QCG services is already available for download. The new version was developed with close cooperation between QCG team and various users communities, especially from the PL-Grid and MAPPER projects. Thus the many of offered enhancements is the response to reported opinions and significantly improves the practical usability of grid and cloud computing.

QCG-Broker 2.6 [3 April 2012]

The version 2.6 of the QCG-Broker service has been released and deployed in PL-GRID infrastructure. Main changes include additional form of description of jobs (a simple script with “#QCG” directives) and a set of “qcg-” commands to interact with the infrastructure. The motivation for both extensions was to simplify the process of defining as well as controlling of experiments and to make the process similar to the approach well known and used in queuing systems.

QosCosGrid 2.4 [20 December 2011]

Just before New Year, a new version of QosCosGrid has been published. We hope the extensions and improvements included in this release will importantly contribute to further development of new and existing Grid infrastructures.

The first MAPPER review [24 November 2011]

During the first review of the MAPPER project, the QosCosGrid stack has been successfully presented in the two demanding multiscale scenarios. Within the loosly-coupled scenario, QCG has been utilized to create advance reservations for the efficient workflow execution, while within the tightly-coupled one to create advance reservations and run co-allocated jobs simultaneously on several clusters.

QCG deployments across Europe [18 September 2011]

QosCosGrid stack has been already deployed on 4 production sites being part of the PL-Grid e-Infrastructure in Poland, namely Cyfronet, PSNC, WCNS and TASK. Additional two deployments has been perfomed in Munich on LRZ cluster and London on UCL cluster. Works on further deployments in other places and communities, such as EGI and PRACE, are in an advanced stage.

QosCosGrid at International Supercomputing Conference 2011, Hamburg, Germany [21 June 2011]

During the ISC'11 conference the EU funded MAPPER project has organized a joint meeting with both PRACE and EGI project representatives working together under the MAPPER Task Force. The main aim of the Task Force, established after a series of meetings over the last three months, is to enable a closer collaboration among resource providers and multi-scale application communities at the European level. Another goal is to support the execution and management of multi-scale distributed applications on example production sites. Two distributed multi-scale application scenarios have been selected as pilot jobs for the first MAPPER review, 24th November 2011. The QosCosGrid middleware together with application tools will be deployed on selected production EGI sites in Poland, Germany and UK as well as PRACE sites, SARA and CINECA

QosCosGrid in Mapper [April 2011]

It was decided to use the QosCosGrid middleware to multi-scale computations in the Mapper project. Installations of the QosCosGrid middleware at production sites in Europe, including EGI and PRACE machines, are currently being discussed.

QCG release 2.0 [16 April 2011]

We are happy to introduce a next relase of QosCosGrid. This is the first release after finishing the QosCosGrid project and takes a number 2.0.

QosCosGrid middleware deployed in PL-Grid [March - April 2011]

QosCosGrid was successfully deployed on the PL-Grid infrastructure in Poland. Currently the QCG middleware is available in Poznan Supercomputing and Networking Center as well as in AGH Cyfronet in Krakow. Further deployment are planned.

QosCosGrid project page moved [March 2010]

After the end of QosCosGrid project, the old www.qoscosgrid.org page was moved to the  archive. The new page is strictly related to the QosCosGrid middleware and further QosCosGrid sollutions.
