Hello together,
the calculated processor time of the download workunits (time left shown in the 6th column of the "work"-sheet) seems to be sometimes wrong which causes that not enough WUs are downloaded.

Because of the often server outages I set preferences to download WUs for 5-7 days work. I get normally WUs which take 3 hours to compute and they really take 3 hours. But sometimes I get a WU which shows 19,5 hours computation time. But in reality they take 3 hours to be done, too!

At the moment I have 2 of these WUs in my queue. Both starting with "04ja04aa.7402..." as ID. The problem is, that boinc "thinks" that there is work for nearly 2 days in the queue but in fact there is only work for 6 hours.

Maybe there is a little bug in this and maybe it affects the calculation of credits, too?

Greetings,
Andreas Voßloh

Hi,

A known problem, reported on these message boards several times. This was caused by a batch of work units with an incorrect "rsc_fpops_est" (An estimate of the average number of floating-point operations required to complete the computation. This used to estimate how long the computation will take on a given host.)

As far as I am aware, it does not affect granted credit - but I may be wrong...
