I am running seti@home and rosetta@home on a 25%/75% resource share thru BOINC. I started only yesterday so am new to this.

When seti runs, the time To Completion counts down as I would expect. But when rosetta runs, the time To Completion counts up. What does it mean for the time To Completion to count up?

By the way, both the CPU time and the Progress (percentage) both count up for both seti and for rosetta, as I would expect. I am using setiathome 4.18 and rosetta 4.79, on an iMac G5 running OS X 10.4.4.

R@H usually only updates the status at multiples of 10%. This will tend to make a saw toothed graph of the estimated time to completion.

The time to completion works out the average rate your computer is crunching the data and then divides the remaining data by this to work out how long it will take. If your computer cpu slows down for any reason then the data will take longer to crunch hence the time increases.

eg.
100% cpu for 100 units will take 1:00
if the cpu drops speed to 90% the 100 units will take 1:06 hence the time will count upwards for a period of time.
so possibly the clock is just counting up as your compter gets slower due to workload/ memory status etc. usually i see the clock count down for 10-15 seconds then up for 2-3.
