Detailed Description¶

The MegaKernelTracer class implements a ray tracer using a mega-kernel strategy.

This tracer processes rays in batches as they propagate through a beamline. It generates rays from source definitions, traces them through optical elements, and records interactions according to configurable event masks.

Key features: * Supports both sequential and non-sequential ray tracing modes. * Uses Alpaka to enable parallel execution across multiple backends (CPU, GPU, etc.). * Manages critical resources such as ray buffers, event buffers, and material data, ensuring optimized memory usage and efficient host–device data transfers.

Workflow: * Generate rays from sources. * Execute the mega-kernel tracing function. * Compact recorded events to optimize memory transfers. * Transfer compacted recorded events back to the host. * Aggregate results from all batches into a final Rays object for output.
