ECP SOLLVE: Validation and Verification Testsuite Status Update and Compiler Insight for OpenMP

TL;DR

This paper provides an update on the ECP SOLLVE validation and verification testsuite for OpenMP, assessing compiler support and implementation progress across multiple vendors for recent OpenMP standards.

Contribution

It offers a comprehensive evaluation of compiler conformity and implementation status for OpenMP 4.5, 5.0, and 5.1 across major vendors.

Findings

Varied support levels among vendors for new OpenMP features

Progress in compiler compliance with recent OpenMP standards

Identification of gaps in implementation across platforms

Abstract

The OpenMP language continues to evolve with every new specification release, as does the need to validate and verify the new features that have been introduced. With the release of OpenMP 5.0 and OpenMP 5.1, plenty of new target offload and host-based features have been introduced to the programming model. While OpenMP continues to grow in maturity, there is an observable growth in the number of compiler and hardware vendors that support OpenMP. In this manuscript, we focus on evaluating the conformity and implementation progress of various compiler vendors such as Cray, IBM, GNU, Clang/LLVM, NVIDIA, Intel and AMD. We specifically address the 4.5, 5.0, and 5.1 versions of the specification.
