I got one! I got an AP! I haven't seen one in a long time.

Edit: I seem to have passed 2 Million credits recently. Yay!



Congratulations on your milestone! Keep on crunching.

I agree that that seems to be true. What I have noticed is that high MB production and having the replica running don't seem to coexist, one can either have one or the other but not both. At least it would appear that way to me, of late.

Looking at the Munin graphs for MBs reminds me of driving a four cylinder pickup in West Virginia, one starts up a hill, down-shifts to fourth, down-shifts to third - foot pressed to the firewall... and it just... won't... go... any... faster...

That's right! No synthohol for us, the True Believers.

The replica is back online, 26K seconds behind - but, Yea!

No worries, Swibby Bear - questions answered help everyone. I (and most everyone else) have had my share of of "D'oh!" moments. Being polite and considerate is a wonderful thing, keep doing it.

Thanx Matt, you rock!

(You do know I was only being hyperbolic, yes?)

No worries, it will be fixed during the next weekly maintenance. ;^)

I was about to ask that myself. All I am getting is "no work sent" without a qualifier across 9 boxes.

Four? We want to encourage them, not kill them!

crude estimation says there are about 12K MB WU per channel, at 6/second there is about 60-90 minutes until the server scrapes the bottom of the barrel

Akio, you can go here:

http://setiathome.berkeley.edu/sah_status.html

also available from the S@H web page as "Server Status Page" - referred to as SSP.

Wave goodbye to the short-term cricket graphs for the gigabitethernet 6_17. I still don't understand why this is not working, it apparently has not been moved and either it is or is not part of the UC Berkeley network, why would that make any difference? It is was a useful tool to gauge server performance, why is it being hidden?

Probably because they are looking at other options right now.
I would imagine the IT guys are using a tool like Cisco Prime(or the older Cisco Works) for their internal needs. If the school year isn't yet over I imagine it is ending soon. Which would likely put the priority to replace the external graphing tools low on the list.


Thanks, much better than the last explanation I read. Although, as you suggest, it is unlikely to happen tomorrow...

they can fix it during the maintenance outage, let the staff have a holiday weekend - at least the project hasn't crashed yet, thank you Mrs. Murphy...

The cricket graph is reading correctly, it has been changed to reflect how much UC Berkeley cares about the S@H project. ;^)

Remember, the flow of Tasks from the Scheduler is not a continuous feed. The Feeder only holds about 200 Tasks at a time. It refills every 5 seconds or so, but with so many hosts asking for work at any given time, once that 200 is allocated, everybody else gets the "No Tasks Available" message until the Feeder refills. It's all a matter of timing.


So the system saturates at 200*12*60 or 144,000 WU/hour? Results returned is currently ~48K/hour leaving excess capacity of nearly 100K/hour currently. If the feeder empties before all requests are filled perhaps it should refresh more rapidly than about every 5 seconds... (it does not escape me that this is approximately equal to the maximum result creation rate)
Also, there is 35-65MB/sec of data leaving the server and not (visibly) going to the lab - that's a lot of work units going somewhere considering all of my boxes are getting the "no work available" message, as is nearly everyone else - maybe Charles Long bought all the servers in new mexico...

The lab (8_34) doesn't show a corresponding huge inflow of data. (unless I have the wrong cricket for it...)

The cricket graphs show 40-60 MB/s going out to somewhere. Not reaching the users, apparently.

updated my cabundle. crt - the link would not let me download it, still no joy - how do I fix this?
