Exascale application preparation services
The first Exaflop-capable supercomputers are imminent, and Juelich Supercomputing Centre is preparing accordingly with a wide range of associated activities [reference to NIC-Symposium paper will be added]. These include the installation and integration of the large GPU-based JUWELS Booster module expected to enter production by the end of 2020.
Apart from coming architectural changes, why should you care? Better scalability of your applications enables you to tackle bigger scientific problems. Imagine possibilities arising from much larger system sizes, increased resolution, or more detailed problems because execution time or memory allocations are less of a constraint.
Talking about time, efficient large scale jobs also mean you do not have to wait for your results to become ready at the end of the project period after months of running jobs. Ideal scalability assumed, your turnaround time will shrink with job size and you are ready to start the next project earlier. You might get your results from a single job.
The current JUWELS Cluster now accepts jobs with up to 1024 nodes as part of standard scheduling. Please refer to the page listing specific hints for tuning large jobs and known (and resolved) issues.
Beyond that, to prepare users of JSC computer systems and their applications, our extensive education, training and support services continue to be expanded to assist with the efficient use of current HPC systems and get ready for upcoming systems.
