As I know, there is an open source version of OpenCL with CPU support and it is available here: POCL . You may try this one. Thank you elstaci for your reply and providing those links. The OpenCL standard does not specify how the abstract execution model provided by OpenCL is mapped to the hardware. You can enqueue any number T of threads (work items), and provide a workgroup size (WG), with at least the following constraints (see OpenCL spec 5.7.3 and 5.8 for details): how to remove outlook rules https://bobbybarnhart.net

Webcase, we start as many threads as there are rows in the matrix. OpenCL may execute these threads in any order, or in parallel (that’s what we count on!), which means that we can make no assumptions about execution order. Each thread needs to know which row it is working on: we determine this by obtaining the index (or: global id) of the thread.
