UMD 3.11.0 [16 February 2015]
The new versions of QCG-Computing and QCG-Notification services for Scientific Linux 6 were included in a fresh UMD release and they are already available in the UMD repository.
UMD 3.9.0 [10 November 2014]
UMD 3.9.0, which includes updated versions of the main QCG packages, was just released. Among others the new QCG packages provide better support for parameter sweep jobs, new resource filters and improvements in data transfers.
PLGrid Plus book [September 2014] eScience on Distributed Computing Infrastructure is a new position presenting results of the PLGrid Plus project. The book is available on Springer website. Among others, the book includes publications about the QosCosGrid - see the Publications section.
QCG-Icon 1.5.0 [20 August 2014]
A new version of QCG-Icon has been released. The main improvement of the program is a support for monitoring of applications using XMPP, e-Mail and QCG-Monitoring service. A new release may be downloaded from this webpage.
UMD 3.5.0 [20 February 2014]
The next update of UMD has been released. The UMD 3.5.0 complements the current QCG family by the new versions of QCG-Broker and QCG-Client.
QCG-Monitoring [11 February 2014]
QCG users are already offered by QCG-Monitoring, a new flexible service for tracking the application execution. With help of monitoring templates, the application progress may be presented in a fully customized form, e.g. application specific tables and charts. More information about the service can be found on the QCG-Monitoring web page.
UMD 3.4.0 [29 January 2014]
A new relase of Unified Middleware Distribution was just published by EGI. The current release includes improved versions of two core QosCosGrid services, namely:
QCG-Computing-3.2.0 and
QCG-Notification-3.2.0.
EGI H2020 workshop [08 December 2013]
On 4-6-th December 2013 EGI towards Horizon 2020 Workshop took place in Amsterdam. The meeting aimed to present the EGI strategy and discuss Horizon 2020 Work Programme 2014-2015 with existing and new user communities, research infrastructure representatives, NGIs and EIROs, resource centres as well as technology providers. The QosCosGrid middleware, which is already an integral part of European e-Infrastructure, has been represented by Tomasz Piontek.
QCG in UMD [12 September 2013]
We can officially announce a big success of QosCosGrid that is joining to EGI Unified Middleware Distribution (UMD). The UMD is a software repository for grid middleware systems and can be seen as Apple App Store or Android Market. The entering of QosCosGrid to UMD means that the system passed restrictive procedures that proved its high maturity and usefulness. Starting from now computing centers accross Europe can easily and safely deploy the QCG components on their sites.
QosCosGrid
The QosCosGrid (QCG) middleware is an integrated system offering advanced job and resource management capabilities to deliver to end-users supercomputer-like performance and structure. By connecting many distributed computing resources together, QCG offers highly efficient mapping, execution and monitoring capabilities for variety of applications, such as parameter sweep, workflows, MPI or hybrid MPI-OpenMP. Thanks to QosCosGrid, large-scale applications, multi-scale or complex computing models written in Fortran, C, C++ or Java can be automatically distributed over a network of computing resources with guaranteed QoS. The middleware provides also a set of unique features, such as advance reservation and co-allocation of distributed computing resources.
QCG Middleware
QosCosGrid provides:
- the most efficient remote access to computational resources in a single cluster or many clusters in Poland and Europe,
- automatic steering of various types of complex computing experiments ranging from multi-parameter sweep studies to cross-cluster executions of parallel applications,
- fully transparent integration with parallel programming and execution environments like OpenMPI and ProActive located on many computing clusters,
- support for Quality of Service (e.g. start time) based on advance reservation mechanisms,
- shorter waiting times and improved resource utilization by hierarchical grid- and local-level job scheduling,
- management of input and output files in distributed computing clusters,
- efficient integration between services and queuing systems ensuring high performance and reliability of the overall system,
- extensible, open and standard based architecture supporting OGF DRMAA, JSDL, BES and HPC Profile with pluggable modules,
- secure communication channels using transport level (SSL/TLS, X.509) and message level (SAML2.0) mechanisms,
- delivered together with command-line, graphical, web-based or even mobile phone tools for end users and administrators,
- fast and reliable installation procedures.
QosCosGrid consists of the following components:
