Scalability

Scalability is a metric which characterizes how well software is able to make good use of additional hardware, like CPU cores or cluster nodes. Scalable software makes good use of additional hardware to perform work faster (strong scalability), or to perform more work (weak scalability). Experiments can be performed with which to compute scalability efficiencies, for example. This is mostly relevant for developers working on the LUE software.

See the experiments page for general information about scalability and performing scalability experiments. The quick start page describes how to perform scalability experiments using an example model. It makes use of the lue_scalability.py command.

Note

Use optimized / release builds when performing performance or scalability experiments.
