LUMI Architecture

Presenter: Emanuele Vitali (LUST)

Some insight in the hardware of LUMI is necessary to understand what LUMI can do and what it cannot do, and to understand how an application can be mapped upon the machine for optimal performance.

Q&A

1. Is there an output that informs you about the efficiency of your mapping?

   • Tomorrow we will have a talk that covers binding of resources in your jobs. This will also show some examples that can be used to inspect your mapping. To find out if you have an efficient mapping, benchmarking and profiling your code is usually the best method. On Thursday morning, HPE will provide three talks on performance analysis tools.
