= QCG Infrastructure Components = The !QosCosGrid stack consists of a set of components playing different roles in a grid/cloud computing. On this page we present general description of main QosCosGrid components as well as description of basic relations between those components in a typical scenario. If you need more detailed information about functionality as well as configuration and installation procedures of particular QCG components follow links presented in the table: ||= Component =||= Main function =|| || [[http://www.qoscosgrid.org/trac/qcg-computing|QCG-Computing]] || Basic Execution Service (BES) with Advanced Reservation Support || || [[http://www.qoscosgrid.org/trac/qcg-notification|QCG-Notification]] || Notification capabilities based on brokered version of OASIS WS-Notification standard || || [[http://www.qoscosgrid.org/trac/qcg-broker|QCG-Broker]] || Resource Management and Brokering service || || [[http://www.qoscosgrid.org/trac/qcg-openmpi|QCG-OpenMPI]] || Extended version of OpenMPI library supporting cross-cluster job execution || || [[http://www.qoscosgrid.org/trac/qcg-core|QCG-Core]] || Common library for !QosCosGrid elements || || [[http://www.qoscosgrid.org/trac/qcg-tools|QCG-Tools]] || Various elements extending the !QosCosGrid functionality ||
