I ran into this error while running
cuda-memcheck. The error comes from a
cudaMemsetAsync statement in a library that is too big to make an example here. The msesage is:
========= Host API memory access error at host access to 0x302000000 of size 13 bytes ========= Invalid start allocation on access by cudaMemset destination.
13 is the number of bytes used in
cudaMemsetAsync (just a number I used to test).
CUDA_CHECK(cudaMemsetAsync(data_ptr, c, 13, stream));
I tried to search the meaning of this error, but Google does not show any result. Does anyone know what could be the problem?
