Thread Trace Part 1 introduces ROCprof Compute Viewer (RCV), a GUI tool for analyzing AMD GPU kernel performance using SQTT (thread trace) technology. The post explains how to capture traces with rocprofv3, analyze instruction timing and stalls, and investigate performance bottlenecks by connecting source code to executed ISA instructions. It is the first in a three-part series targeting kernel developers and profiling tool developers working with ROCm 7.13 or later.
