CSRB Embedded Cluster

The Embedded cluster consists of a number of *fairly old* ARM-based devices, intentionally selected to provide a very challenging development and testing environment. Working with such low-spec hardware inherently highlights bottlenecks, inefficient threads/locks management, data management etc.
