Description: Infrastructural and procedural changes have been put in place to support parallel execution of Abaqus User Subroutines.

For threads, a number of parallel primitives has been exposed in Fortran that allow you to write safe multithreaded code in Fortran. These primitives have also been exposed in the C++, although this language has its own facilities for writing multithreaded code.

For MPI, full native support has been enabled and provided for both Fortran and C++. All MPI calls are available from within Abaqus user subroutines.

Special arrangement have been made to provide thread-shared and thread-local storage for users' needs.
