Detailed Description

template<typename T>
class cntr::distributed_array< T >

Auxiliary data structure for handling set of data blocks and includes usual MPI processes on them.

Purpose

Auxiliary data structure for handling of data blocks (total number is n_) , which are stored in * contiguous form in member data_ and includes usual MPI routines. The class identity is marked by * tid_ \( \in (0,\ldots,ntasks_-1) \) and the value of the tid_ is just the MPI rank or 0 if MPI is not defined. Each data block j is owned by precisely one process, which is given by \( tid * _map(j) = tid_\). The member maxlen marks the maximum size reserved for the block. NOTE: even if the block is not owned by the process, the space for the data is allocated; the ownership plays a role when the data are manipulated
