I recently bought Radeon HD 7870 and am studying on OpenCL programming on Linux.
Device driver version is CAL 1.4.1741.
When test my programs, I found that two programs demading almost all global memory work normally without errors.
In my assumption, because a program occupies the global memory and not yet terminates,
the second program I execute later cannot use GPU and returns an error.
However, there is no error and both work correctly.
When I was doing similar things in my old NVIDIA GPU, it returns out of memory error.
What makes this difference? Does Radeon support automatic memory swap to host memory? or is it a bug?
