 The key component of every administrative domain in !QosCosGrid is the [[QCG_BES|QCG BES/AR service]], which gives the 
-remote access to queuing systems resources. QCG BES/AR supports advance reservations, parallel execution environments - OpenMPI, !ProActive and MUSCLE with coordinators responsible for synchronization of cross-cluster executions (see [[QCG_libraries_and_cross-cluster_communication|Cross-cluster communication]]) and [[QCG_DataMovement|QCG Data Movement services]] for managing input and output data. The another relevant service at the administrative domain is in charge of notification mechanism and it is called [[QCG_Notification|QCG Notification]]. These services are tightly integrated and connected to the Grid-level services. The critical service on this level is [[QCG_Broker|QCG Broker]], that is a meta-scheduling framework controlling executions of applicaitons on the top of queuing systems via Smoa Computing services. !QosCosGrid architecture is depicted in the figure presented below.

 === End-user Information ===
+The demanding nature of scientific simulations requires a new e-Infrastructure that is able to simultaneously manage heterogeneous resources, such as computing resources, storage and network to guarantee the level of Quality of Service 
+(QoS) required by end-users for their applications, especially a large number of legacy applications designed to run in parallel. Addressing the need of end-users to run large scale complex simulations we have built a system capable to bring supercomputer-like performance for advanced applications, including sophisticated parameter sweep experiments, 
+workflows, and more importantly cross-cluster parallel computations. For more information see this [[user_information|section]].
