Nvidia CUDA Subsystems Assignment Answers

Question:

Nvidia CUDA Subsystems: Which three of the following statements are true?

e) Grid-stride loops guarantee fully coalesced memory reads.

Nvidia CUDA Subsystems Answer and Explanation

e) False. Grid-stride loops do not guarantee fully coalesced memory reads by themselves. Achieving fully coalesced memory reads depends on how memory accesses are structured and aligned within the kernel.

Therefore, the three true statements are: a, c, and d.
