Description (last modified by egourgoulhon)

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. 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).

This work is an extension of #15916, within the ​SageManifolds project (actually the code in this ticket is the basis for parallelization in SageManifolds 0.8).
