| Subject: Big puzzle on processing times (WUs with same dates, AR & TerFlops) |

I have just processed two couples of different WUs, and got radically
different processing times.
The first group of two WU is -
25au03ab.6263.3617.573572.101
AR 0.547, TeraFlops 3.986, crunch time 5.054 hrs (about normal)
25au03ab.6263.3617.573572.28
AR 0.547, TeraFlops 3.984, crunch time 6.436 hrs (like a VLAR)
Second group of two WUs -
25au03ab.6263.3617.573572.87
AR 0.547, TeraFlops 3.991, crunch time 5.233 hrs (about normal)
25au03ab.6263.3617.573572.28
AR 0.547, TeraFlops 3.991, crunch time 6.433 hrs (like a VLAR)
I have been using my PC box for word processing during both these sets
of results today.
Anyone able to speculate as to the wild crunching time differences?
NOTE: I run 4 instances of the S@H CLI, under Driver & Spy to a proxy
(SETIQueue) on my box. It is a dual 2.8GHz Xeon, with HT active,
under WinXP Pro. This box is part of a small farm.
With this set up I achieve times for VLARs @ 6.0-6.5 hrs and for
VHAR the time drops to 4.0-4.25 hrs. Normal AR processing is in
the range 4.75-5.25 hrs.
