WebC 如何在OpenMP中正确使用分区锁?,c,locking,openmp,C,Locking,Openmp WebOpenMP (Open Multi-Processing) is an application programming interface (API) for shared memory parallel computing. It is supported on numerous platforms, including Linux and Windows, and is available for the C/C++ and Fortran programming languages. The API consists of a set of directives, a software library, and environment variables.

WebThe sections clause is a worksharing construct; the section clauses that are contained in it will be picked and executed by the threads in the team. If the sections clause is not associated with a nowait clause, an implicit barrier takes place at the end; waiting for all section directives contained to complete. WebParallel Computing with OpenMP#. OpenMP is an API that implements a multi-threaded, shared memory form of parallelism. It uses a set of compiler directives (statements that you add to your code and that are recognised by your Fortran/C/C++ compiler if OpenMP is enabled or otherwise ignored) that are incorporated at compile-time to generate a multi …
