Hi,
Sorry for the delayed response. Since I set most of this up for a paper
submission, I have only simulated the system that we were interested in (64
cores). Below are approximate simulation times for that system on our
Condor cluster (2 & 4 core P4 Xeons and 2 core Opterons):
-------64 cores-----------
simsmall: simmedium: simlarge:
- blackscholes 00d05h10m 00d16h24m 01d22h39m
- bodytrack 02d05h27m 10d18h19m
- canneal 01d05h38m 03d03h57m
- dedup 00d17h14m
- facesim <- more than 20d: incomplete ->
- ferret 00d22h48m 02d23h49m
- fluidanimate 02d14h40m 02d20h03m
- freqmine 02d04h20m 04d18h53m
- vips 02d20h07m 05d15h32m
- x264 11d01h32m
-------64 cores-----------
Mark, another student in our group, might be able to give better estimates
for systems with fewer simulated cores. Hopefully this is useful,
Joel
