The Tier-0 system SuperMUC is hosted by the Gauss Centre for Supercomputing (GCS) at the Leibniz-Rechenzentrum der Bayerischen Akademie der Wissenschaften (Leibniz Supercomputing Centre of the Bavarian Academy of Science and Humanities) in Garching near Munich. In June 2012 SuperMUC was Europe's fastest supercomputer and the number 4 on the world-wide TOP500 list. Already starting in August 2011 a migration system nicknamed SuperMIG was provided to port applications to the new programming environment. The migration system will be integrated as one fat-node island into the SuperMUC system. This best practice guide provides information about SuperMUC in order to enable users of the system to achieve good performance of their applications. The guide covers a wide range of topics from the detailed description of the hardware through information about the basic production environment including how to login and the accounting procedure as well as information about porting and submitting jobs, up to tools and strategies on how to analyze and improve the performance of applications.
