It supports both interactive and batch modes for gathering profile data, and supports MPI, OpenMP and single-threaded programs. Debug with Arm DDTĪrm MAP is a parallel profiler that shows you which lines of code took the most time and why. It provides a complete solution for finding and fixing problems whether on a single thread or thousands of threads.

It includes static analysis that highlights potential problems in the source code, integrated memory debugging that can catch reads and writes outside of array bounds, integration with MPI message queues and much more. Forge includes three components: DDT, MAP and Performance Reports and can be used for serial or parallel applications relying on MPI and/or OpenMP.Īrm DDT is a powerful, easy-to-use graphical debugger. GCC OpenMP project page (includes implementation status)Īrm Forge is a software development toolkit designed to assist Linux developers write correct, scalable and performance applications for a variety of hardware architectures, including Arm (aarch64), x86_64, and NVIDIA GPUs.GCC binary builds are provided by Linux distributions, often with offloading support provided by additional packages, and by multiple entities for other platforms – and you can build it from source. The devel/omp/gcc-12 (OG12) branch augments the GCC 12 branch with OpenMP and offloading features, including relevant backports from the GCC 13 development branch. GCC 12 has the initial support of OpenMP 5.1 and extends the OpenMP 5.0 coverage.

Since GCC 11, OpenMP 4.5 is fully supported for Fortran and OpenMP 5.0 support has been extended for C, C++ and Fortran. OpenMP 5.0 is partially supported for C and C++ since GCC 9 and extended in GCC 10. OpenMP 4.0 is fully supported for C, C++ and Fortran since GCC 4.9 OpenMP 4.5 is fully supported for C and C++ since GCC 6 and partially for Fortran since GCC 7. The free and open-source GNU Compiler Collection (GCC) supports among others Linux, Solaris, AIX, MacOSX, Windows, FreeBSD, NetBSD, OpenBSD, DragonFly BSD, HPUX, RTEMS, for architectures such as x86_64, PowerPC, ARM, and many more.Ĭode offloading to NVIDIA GPUs (nvptx) and the AMD Radeon (GCN) GPUs Fiji and Vega is supported on Linux.
