Device fission is an addition to the OpenCL* specification that gives more power and control to OpenCL programmers over managing which computational units execute OpenCL commands. Fundamentally, device fission allows the sub-dividing of a device into one or more sub-devices, which, when used carefully, can provide a performance advantage, especially when executing on CPUs.
Device fission is defined in the OpenCL 1.2 specification and is available with Intel SDK for OpenCL Applications 2012 as an OpenCL 1.1 extension.
