Outline Outline � Motivation & History � Production UNICORE 5 � Features � Recent Developments � Architecture � UNICORE 6 � Grid Standards � Architecture � Summary 2
Motivation: Why UNICORE? Motivation: Why UNICORE? � Scientists need computational and storage related resources 3
Motivation: Why UNICORE? Motivation: Why UNICORE? � Supercomputers are managed by Resource Management Systems (RMSs) that handle the scheduling � But: There are many RMSs available � A proprietary way of job submitting Resource Management System � IBM Loadleveler � llsubmit … � Torque Resource Manager � qsub … � Different job description languages (# of nodes, memory requirements…) 4
Motivation: Why UNICORE? Motivation: Why UNICORE? � Solution: Grid System UNICORE � Define job workflows in abstract manner � Immediate portability of job definitions for other systems with other architectures � No ‘learn overhead’ if a new RMS is used � Applications across multiple supercomputers/clusters � ‘going meta’ 5
