I do not see a problem with having multiple 2D arrays allocated with cudaMallocPitch () even if they should not all use the same pitch value.
WebOct 18, 2024 · Pitch is a linear memory allocation calculated from the user provide’s 2D sizes, with the required padding to ensure row major access correctly. Block linear layout is to optimize the coherence of 2D (and 3D) access patterns both for reading and writing purposes. There is no block height in pitch surfaces. It is simple pitch storage format. 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).
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.
