Detailed Description

template<class Resource>
class uni20::cuda::ResourcePool< Resource >

Fixed-capacity pool of preconstructed provider resources.

Non-blocking waiters receive released resources in FIFO order. The pool is independent of scheduler and CUDA stream policy and must outlive all leases and queued acquisition awaiters.
