  • Ticket #18100 – Description

    initial v11  
    1 This ticket implements parallelization of basic operations (arithmetics, contractions) on tensors on free modules of finite rank. The parallelization is performed by means of Python's module `multiprocessing`, via the decorator `@parallel`.
     1This ticket implements parallelization of basic operations (arithmetics, contractions) on tensors on free modules of finite rank. The parallelization is performed by means of Python's module `multiprocessing`, via the decorator `@parallel`. It is implemented in computational methods of classes handling tensor components: `sage.tensor.modules.comp.Components` and `sage.tensor.modules.comp.CompWithSym`. The user can control the number of processes involved in the parallelization via the global function `set_nproc`, with `set_nproc(1)` switching off the parallelization (the default).
