apiInitMPI()

static void apiInitMPI ( pastix_data_t *  pastix, PASTIX_Comm  comm, int  autosplit  )

inlinestatic

Internal function that setups the multiple communicators in order to perform the ordering step in MPI only mode, and the factorization in MPI+Thread mode with the same amount of ressources.

Parameters

[in,out]	pastix	The pastix data structure to initialize.
[in]	comm	The MPI communicator associated to the pastix data structure
[in]	autosplit	Enable automatic split when multiple processes run on the same node
