Run with the option -info and look for output of the form Many brVecAssemblyBegin_MPIXXX:Stash has MM entries, uses nn mallocs. Many brto determine the appropriate value, MM, to use for size and Many brVecAssemblyBegin_MPIXXX:Block-Stash has BMM entries, uses nn mallocs. Many brto determine the value, BMM to use for bsize Many br
