Detailed Description

Tool providing HIP-based traccc spacepoint formation algorithm.

This tool constructs the traccc device spacepoint formation algorithm, configured to run on with HIP backend. It relies on separate tools to provide the host/device memory resources and the vecmem copy object.

Currently only pixel spacepoint formation is implemented in Traccc
