I\'m seing a patter of different times required to complte each work sub-unit (30min of simulation).

I\'m seing 5 subunits completing in about 3 seconds then every 6th completing in 26seconds.

What\'s going on?
This is Linux 2.6.5-7.111 (Suse 9.1)
running the latest boinc and climateprediction software.
I just downloaded them 5 minutes ago.

Much thanks!

Here\'s some data to show what I\'m talking about:

At each 6th timestep, there is a more computing intensive radiation calculation.
