Hello. I’m developing some matrix solver program with MAGMA.
MAGMA code is converted and optimized for my develop environment.
When I use the cudahostregister to use async functions, there is some error.
It is fixed by allocating the GPU memory with enough free memory(about ~500~600 Mbyte.)
So I suspect that cudahostregister uses some resources of GPU.
Are there anyone, who knows about how the cudahostregister works?
