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.
