Abstract

OpenMP is a defacto standard API for shared memory programming with widespread vendor support and a large user base. The OpenMP Architecture Review Board has sanctioned an interface specification known as the ”OpenMP Runtime API for Profiling” to enable tools to collect performance data for OpenMP programs. This paper describes the interface and our experiences implementing it in OpenUH, an open source OpenMP compiler.
