1) Message boards : Number crunching : MT and single-CPU point differences (Message 59062)

When I run an MT N-Body Simulation WU on 2 or more cores I average under 6 points per CPU per hour. Example WU: http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=385527079 (#520156 is me)

When I run single CPU MilkyWay@Home WU's I average over 40 points per hour. Example WU: http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=386935266

Why the huge difference??

Just got this task http://milkyway.cs.rpi.edu/milkyway/workunit.php?wuid=361047651 requiring an estimated 14,547,000 Gflops to complete in 9 days!!! Put another way, BM estimates it will take 15136 hours (630 days).

I know it takes time for the correction factor to kick in, but something is way off here.
