Detailed Description
Allocates at least width (in bytes) * height bytes of linear memory Padding may occur to ensure alighnment requirements are met for the given row The change in width size due to padding will be returned in *pitch.
Currently the alignment is set to 128 bytes
- Parameters
-
[out] dptr Pointer to the allocated device memory [out] pitch Pitch for allocation (in bytes) [in] width Requested pitched allocation width (in bytes) [in] height Requested pitched allocation height
If size is 0, no memory is allocated, ptr returns nullptr, and hipSuccess is returned. The intended usage of pitch is as a separate parameter of the allocation, used to compute addresses within the 2D array. Given the row and column of an array element of type T, the address is computed as: T pElement = (T*)((char*)BaseAddress + Row * Pitch) + Column;
- Returns
