Matrix-Multiplication Profiling Examples

This code contains a global memory, shared-memory tiled, and joint shared-memory and register-tiled matrix matrix multiplications.

Module 1: Nvidia Nsight Compute

Examples for using Nsight Compute to compare kernel performance.

• 1-1-pinned-basic: (1_1_pinned_basic.cu)
• 1-2-pinned-tiled: (1_1_pinned_tiled.cu)
• 1-3-pinned-joint: (1_1_pinned_joint.cu)

Module 2: Nvidia Nsight Systems

Examples for using Nsight Systems to compare data transfer, and relationship between data transfer and end-to-end time.

• 2-1-pageable-basic: (2_1_pageable_basic.cu)
• 2-2-pinned-basic: (2_2_pinned_basic.cu)
• 2-3-pinned-tiled: (2_3_pinned_tiled.cu)
• 2-4-pinned-tiled-overlap: (2_4_pinned_tiled_overlap.cu)
• 2-5-pinned-joint: (2_5_pinned_joint.cu)
• 2-6-pinned-joint-overlap: (2_6_pinned_joint_overlap.cu)

All programs share the same basic options:

• Three optional positional arguments to set M, N, and K.
• --iters <int> the number of measured iterations (default 5)
• --warmup <int> the number of warmup iterations (default 5)
• --check: check correctness (default false). Only use for small multiplications
