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. 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.

Collaboration with Ukraine [30 August 2013]
Start of cooperation with Ukraine was signed in  Memorandum of Undestanding between Poznan Supercomputing and Networking Center and The Basic Coordination Centre of Ukrainian National Grid. The MoU is opportunity to promote QosCosGrid in East European countries.

QosCosGrid 3.0 [16 July 2013]
A new major release of QCG services has been just published! The 3.0 release includes many improvements that simplify the access to applications and limit the time overhead needed to run or manage jobs in a grid environment. Undoubtedly the newly applied mechanisms, e.g. simplified syntax of QCG-Client commands, enhanced data transfer rate or advanced monitoring capabilities, will allow scientists to concentrate even more on the core of the scientific work.

QCG-Icon 1.4.3 [21 June 2013]
Next version of QCG-Icon is available to download. Since the version 1.0 there were many improvements that wait to be discovered by QCG users.

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:
