Detailed Description

Algorithm executing traccc track finding on the GPU.

The backend-specific track finding algorithm is provided by a dedicated tool, together with the device memory resource.

The algorithm retrieves the device resident traccc track parameter and measurement collection from the event store, passes them to the device track reconstruction algorithm and records the resulting device resident traccc track and track states collections back into the event store.
