I know some of you like to know the batch plan, so here it is...

Batch 13x270 is nearing completion for subfield 3. After that, we will spend a week or two picking some of the low hanging fruit on subfield 7. Then it's back to subfield 3, batch 13x271. This is a very big batch, so I expect it to last until the end of December, possibly into January.

Posting in the wrong forum.

Try https://setiathome.berkeley.edu/forum_help_desk.php - but next time, please give details of your operating system, BOINC version, and what you did prior to the change in behaviour.

Are DS13x271 tasks short (similar to DS13x270)?

No, they will be about twice as long. DS13x270 took about 10 days, so DS13x271 should take about 85 days, assuming FLOPS stay the same.

Which raises the problem of the transition back to long tasks after our machines have adapted to the short runs from subfield 7. You may get a blip of runtime exceeded errors again, followed by another blip when the first resends try to run in half the time. Might be wise to cut down the 'maximum tasks in progress' for a while when the first long tasks are ready to flow out.

Ok. I reduced the "max_wus_in_progress" parameter just to be safe. But just to clarify, the sf7 tasks will average about .7 hours and the future 13x271 tasks average about 1 hour, so they are actually pretty close in time. For comparison the 13x270 which recently completed (just waiting on a few stragglers to trickle in) averaged .5 hours. All these times are from the same 3.6 GHz computer, running single threaded. If you run hyper-threaded, you can double the times for a better runtime estimate.
