Hi Joe,

Not quite clear about your use-case -- you say the data doesn't change between kernel invocations, but then you say it's changed on the host, and needs to be copied back out to the card between kernel invocations? Do you mean that the kernels don't change it, but the host does? Or something else?

Also, are you on an architecture that shares physical memory between the host and the OpenCL device (like Intel OpenCL)? Or are you on an architecture that has separate device memory (like most Nvidia and AMD cards)?
