Detailed Description

Algorithm executing traccc triplet seeding on the GPU.

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

The algorithm retrieves the device resident traccc spacepoint collection from the event store, passes it to the device triplet seeding algorithm, and records the resulting device resident traccc seed collection back into the event store.

The seed finder, spacepoint grid and seed filter configurations are exposed as properties. The magnetic field and the beam spot position are taken from the conditions store for every event.
