Variables

Type Visibility Attributes Name Initial
integer, private, parameter :: nleafbuf = 16384

Depth-first leaf flags of the whole forest, one LOGICAL per tree node. Buffered in chunks of nleafbuf rather than written one node at a time: the byte stream on disk is identical either way, but a tree of a million nodes costs a million individual MPI_FILE_WRITEs otherwise. read_forest consumes the same stream through a buffer of its own.
