Performance Profiling on AMD GPUs - Part 4: Fortran OpenMP Offload Edition

This blog, like the previous articles in the profiling guide series (Part 1, Part 2, and Part 3), is designed to help you systematically analyze and improve the performance of your Fortran OpenMP offload applications running on AMD GPUs. This guide builds upon the foundational skills from the previous articles and introduces profiling techniques specifically tailored for Fortran applications that use OpenMP target offloading.

Introduction to profiling tools for AMD hardware

Getting a code to be functionally correct is not always enough. In many industries, it is also required that applications and their complex software stack run as efficiently as possible to meet operational demands. This is particularly challenging as hardware continues to evolve over time, and as a result codes may require further tuning. In practice, many application developers construct benchmarks, which are carefully designed to measure the performance, such as execution time, of a particular code within an operational-like setting. In other words: a good benchmark should be representative of the real work that needs to be done. These benchmarks are useful in that they provide insight into the characteristics of the application, and enable one to discover potential bottlenecks that could result in performance degradation during operational settings.

Graph analytics on AMD GPUs using Gunrock

Graphs and graph analytics are related concepts that can help us understand complex data and relationships. In this context, a graph is a mathematical model that represents entities (called nodes or vertices) and their connections (called edges or links). And graph analytics is a form of data analysis that uses graph structures and algorithms to reveal insights from the data.
