Data.Array.Accelerate.Array.Data
Description
This module fixes the concrete representation of Accelerate arrays. We allocate all arrays using pinned memory to enable safe direct-access by non-Haskell code in multi-threaded code. In particular, we can safely pass pointers to an array's payload to foreign code.
