A structure that describes some of the traits of this class in terms of its run-time behavior. Some other classes (such as the block matrix classes) that take one or other of the matrix classes as its template parameters can tune their behavior based on the variables in this class.

It is not safe to elide additions of zeros to individual elements of this matrix. The reason is that additions to the matrix may trigger collective operations synchronizing buffers on multiple processes. If an addition is elided on one process, this may lead to other processes hanging in an infinite waiting loop.
