Check What Stuck
OpenCL Programming by Example Knowledge Check
Test your mastery of the core principles.
Question 1 of 4
What is the primary role of the OpenCL host code?
Explanation: The host processor orchestrates the application flow, manages memory buffers, and schedules tasks onto OpenCL compute devices.
Question 2 of 4
Which memory space in OpenCL is shared among all work-items within a single work-group?
Explanation: Local memory is allocated per work-group and is accessible to all work-items within that specific work-group, serving as a high-speed scratchpad.
Question 3 of 4
What is the main benefit of using local memory tiling in matrix multiplication?
Explanation: Tiling caches sub-matrices in local memory, minimizing expensive round-trips to global DRAM and accelerating computation.
Question 4 of 4
How can a developer accurately measure kernel execution duration in OpenCL?
Explanation: OpenCL event profiling APIs provide exact hardware timestamps for submission, start, and completion of queued commands.
