identical tasks running?

(moderation:
I noticed that the names of two currently running tasks are identical and that the times elapsed and to completion are identical. This seems like a duplication of effort. Shouldn't I abort one?
identical tasks running?

Are you sure they are identical? Your Intel-MAC has (according to E@H website) two tasks, but the id's differ: one is *401* and the other *402*.

Alas this is the problem encountered by 59 year olds when their visual focusing acumen deteriorates. Thanks for your quick response. All is well.

Yup, they are different. But not by much, as the 401 and 402 indicates they are nearby in a parameter that specifies celestial/sky position. As discussed, oooh ..... well over a year ago now, the behaviour of work units in runtime along the axis of this parameter approximates a sinusoid ( or parabola maybe ). There's quite a clustering of workunits near the minimum of that curve - meaning they will have very close runtimes on a given machine - and possibly equal runtimes for a pair if each is exactly an equal 'distance' from the minimum. In this case the 'true' runtime minimum would lie b/w the sky positions indicated by 401 and 402.
You see, the sky is analysed in a pattern which would look like tiny little grid squares - if it was marked out for you while looking up at the stars - but this grid is indexed by angular position. The short answer is that one can't neatly wrap a flat newspaper around a basketball without distorting one or both, and the sinusoid mentioned above is a consequence of the choice of the marking out, and the alignment of, the grid that we calculate with.
Cheers, Mike.
