Cuda memory pitch
WebIn this and the following post we begin our discussion of code optimization with how to efficiently transfer data between the host and device. The peak bandwidth between the device memory and the GPU is much higher … WebMar 31, 2016 · With a bit of trial and error, you can come up with an estimated maximum, say 80% of the available memory reported by cudaMemGetInfo (), and use that. The situation with cudaMalloc is generally similar to a host-side allocator, e.g. malloc.

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:

WebOur strategy for using CUDA Memory Pool is to minimize global memory occupation. There is a rule to be obeyed. allocate memory blocks from CUDA Memory Pool when needed, return memory blocks to CUDA Memory Pool immediately when useless. Namely, allocating and freeing memory blocks should be done in ppl.cv.cuda function definition. (1). WebFor allocations of 2D arrays, it is recommended that programmers consider performing pitch allocations using cudaMallocPitch(). Due to pitch alignment restrictions in the hardware, this is especially true if the application will be performing 2D memory copies between different regions of device memory (whether linear memory or CUDA arrays).
