cudaMemGetInfo is really useful function.
That gives programmers device memory info.
But I don’t know how to know main memory info (host memory).
because cudaMalloc allocation minimum 2MB to device memory when call cudaMalloc.
I wonder about does main memory (host memory) allocate minimum 2MB minumum?
So I want to check main memory usage size.
I already try googling, but there are a lot of confuse things…
