It is not that the threads in OpenCL are tiled, but blocked linear.

What is the difference between linear and blocked linear? How to map the blocked linear to the cal's linear? Can you explain it more clearly? Thank you.
Linear is sequential along a single line, blocked linear is sequential within a block and each block is sequential. In tiled mode it usually follows a hierarchical Z pattern.
