The one-time setup overhead times, which include installing the files
on the remote nodes and starting and stopping PVM, are found in
Table D.1. Table D.2 shows the average
elapsed wall-clock times for the calculation of the the four
pixel-based historical scenarios for the Hoh Watershed in
Table 8 with LUCAS running on a single host and
pLUCAS running on 4, 8, 12, 16, and 20 hosts. The averages were taken
over three independent timings. The calculation of speedup and
efficiency are discussed in Section 5.2. Timings were
taken using the UNIX utility /usr/5bin/time.
