It's gonna be a long time before we get fresh APs. We are paying now for the recent gluttony.

You can approximate by how many MB 'total channels to do:' there are. Right now it's at 431, which is pretty much on schedule for new data Tuesday. The recent frequent spurts seem to have been attempts to correct the splitter errors.
My bet is new APs after the Tuesday outage, as usual.

Don't be fooled by the non-zero origin for the Y-axis - we're just back to the normal level of uploads. And nothing has failed over to inr-210.

Yes, in Daily Graph. But when looking at Monthly Graph I see transfers are going back to "normal" and above it, no more AP frenzy???

Just my guess...

If you look at the monthly graph you can see our "normal" AP frenzy traffic. Which is often about 200Mb. The past few weeks there was an uptick in the inbound, first small and then larger, and outbound even went up over 400Mb at one point. It looks odd even on the yearly graph.

If you are going to go down that road my guess it is a farm reporting in a batch mode.

I would love to see one computer download gig worth of work. I wonder how long it would take to process a week on latest hardware running 24 7

Do you want a GB of MB work or AP work. Because a machine doing CPU & GPU can have 1.6GB of AP very easily when they are being produced. For MB 1 GB would be around 2700. Which was about the size of the 10 day queue on my 24 core server before the limits & when we were on MB v6.

I download more than a gig worth of work regularly when APs are being split. A gig worth of APs is only 125 work units. I'll download 900 AP work units before splitting stops. I'll have them crunched in 2 to 3 days. The 100 CPU Astropulse units may take an extra day.

For MB 1 GB would be around 2700. Which was about the size of the 10 day queue on my 24 core server before the limits & when we were on MB v6.

And considering even a mid range video card can knock over 2 WUs at a time in less than 30min that take a CPU core over 3-4 hours to process, 1GB of work doesn't last very long if you have a couple (or more) highend video cards crunching away.

Thank you all for your responses. I agree with you all in the fact that it is easy to download over a gig worth of work at a time.

My 2x690 hosts runs with up to 800 AP WU cache, so it´s about 3.2 GB of data which is enought for 4-6 days of work.

It seems like the scheduler has gone on the blink again, no work has been allocated here for an hour now.

Cheers.

Hmm.
About 40min ago I could report, but work requests would result in "Project has no tasks available" messages. For the last 10min it's been "Scheduler request failed: Couldn't connect to server"
Something's stuck.

I was seeing exactly the same, but something - maybe an automatic watchdog script, at this time of night - seems to have restarted things: I've just got through to report work, and even got one new task allocated (a shortie, of course).

Task lists are also very slow to load on this website, and that new one isn't showing yet. Work to be done during the outrage, methinks.

Just had another look at my log- 3 min ago I was able to report, but still no work allocated.

EDIT and those Scheduler responses are taking almost a minute. Usually it's 5 seconds or less.
