Typedefs

using WorkspaceRequirements = NVCVWorkspaceRequirements

using WorkspaceMemRequirements = NVCVWorkspaceMemRequirements

Functions

inline WorkspaceMemRequirements MaxWorkspaceReq(WorkspaceMemRequirements a, WorkspaceMemRequirements b)

Computes memory requirements that can cover both input requirements.

The resulting memory requriements will have alignment and size that is not smaller than that of either of the arguments.

alignment = max(a.alignment, b.alignment) size = align_up(max(a.size, b.size), alignment)

inline NVCVWorkspaceRequirements MaxWorkspaceReq(const WorkspaceRequirements &a, const WorkspaceRequirements &b)

Computes workspace requirements that can cover both input requirments.

inline void AlignUp(WorkspaceRequirements &ws)

inline UniqueWorkspace AllocateWorkspace(WorkspaceRequirements req, nvcv::Allocator alloc = {})

Allocates a workspace with an allocator specified in alloc (or a default one).

This function is meant as a simple helper to simplify the usage operators requiring a workspace, but its intense use may degrade performance due to excessive allocations and deallocations. For code used in tight loops, some workspace reuse scheme and/or resource pools are recommended.
