Cuda texture Memory Allocation in C

You define it with the texture syntax:

texture<Type, Dim, ReadMode> Name

Where:
Type is the data type (float, int, ...)
Dim is the number of dimensions 1D, 2D, 3D, represented as just the number 1, 2 or 3
ReadMode is the access allowed. Either cudaReadModeNormalizedFloat (a float value in the range [0-1], where ints are converted) or cudaReadModeElementType (The actual value you store in the memory). Reffer to section 4.3.4 of the Cuda Programming Guide[^] for a further explanation.
Name is your variable name

So, say we want a 2D array of integers (to be stored as integers), we would have

texture<int, 2, cudaReadModeElementType> MyIntGrid;
