Restarted large grid run with 59507 and edited 3dscan.h and types.h
Now reads:
COMPUTING FLOW DIRECTIONS
classifying nodata (inner & boundary)
total elements=6783000000, nodata elements=3291487486
largest temporary files:
FILL: 454.84G (488376000000) [6783000000 elements, 72B each]
FLOW: 312.17G (335185201344) [3491512514 elements, 96B each]
Will need at least 909.67G (976752000000) space available in /data1
