I'm developing an open-source API that uses multiple OpenCL devices to compute kernels, adding features like pipelining and load balancing, but now I need to add a device-to-device pipeline such that a GPU will send data to another GPU without touching system RAM, only through inter-pci-e connection. What is the OpenCL API command for that? I guess this command
should have that but its documentation in Khronos site doesn't tell anything about it.
Details about my project:

thank you for your time.
Solved! Go to Solution.
It's depends on the implementation. AFAIK, on AMD platform, MigrateMemObjects currently still uses system memory.
cl_amd_bus_addressable_memory extension is there which supports direct transfer, however I've doubt whether it would be applicable in this scenario or not. Also this extension available for FirePro boards only.

Then a HD7870 has to visit RAM before talking to R7-240.
