This matrix type is identical to MATSEQAIJVIENNACL when constructed with a single process communicator, Many brand MATMPIAIJVIENNACL otherwise. As a result, for single process communicators, Many brMatSeqAIJSetPreallocation is supported, and similarly MatMPIAIJSetPreallocation is supported Many brfor communicators controlling multiple processes. It is recommended that you call both of Many brthe above preallocation routines for simplicity. Many br
