Does CULA support zero copy?

My card is GTX280, and it supports host page-locked memory mapping. But when cula funcution is called, I get runtime error (17).

While CULA supports page-locked memory, it doesn't support this type of memory in zero-copy mode. Zero-copy would force synchronization on every kernel that CULA uses internally, which would result in disastrous performance.

Ok , got it! Much thanks for your reply.
