How to get Access Sample Clauses

How to get Access. End users from both Core and Associate Partners may apply for access to many of these systems via the email address xxxxxxxxxxx@xxxxxxxxxx.xx, where they should apply with a brief description of what HPC platform they wish to access, what simulations they are interested in performing, what software they aim to employ, and how many core hours and disk space they require. To gain access to Tier0 resources, we encourage end users to apply to PRACE. UCL also command access to a vast suit of supercomputers throughout Europe and the US, including SuperMUC(-NG), Blue Waters, Titan and Summit, and are able to allocate time to collaborators on these systems. Once permission has been granted, end users are then put in contact with the associated HPC centre, who will guide them through the process of direct access to the HPC platform, using either SSH, which requires a username/password combination, or GSISSH, which requires Certificates. Both access methods grant the end users access via the Unix command line interface. Either the target simulation codes are already ported and tuned to the existing target HPC architecture, or the end user, working closely with the HPC centre’s experts, can install the simulation codes themselves. However, the efficiency of a tuned simulation code depends on the target simulation, e.g. a small simulation will not scale to 1000s of cores; thus, HPC centres offer a range of tools and services to ensure the target simulations run efficiently. The following tools and services describe how a particular simulation can be tuned to the target HPC platform. It is important to note that, once ported, these same tools and services can be used to prepare the codes for future exascale HPC systems using that current HPC platform. In conjuncture with these tools, we are preparing for exascale systems via the co-design process, wherein vendors work with end users to ensure future supercomputers are constructed to ensure key applications will run efficiently. CompBioMed is actively involved in co-design, and this is addressed in Section 10.2.
