Public Attributes
size_type	stack_size {}
	Per-thread CUDA stack size (ignored if zero) [B].
size_type	heap_size {}
	Global dynamic CUDA heap size (ignored if zero) [B].

Detailed Description

Set up GPU capabilities and debugging options.

Stream sharing and synchronization might be helpful for debugging potential race conditions or improving timing accuracy (at the cost of reducing performance).

The CUDA heap and stack sizes may be needed for VecGeom, which has dynamic resource requirements.
