Doc, I have a noob question about the BitMinter client.
Would you say that minimizing the client accomplishes the same thing speed-wise as switching it to Performance Mode? The reason I ask is because I'm wondering whether adding a check box under Options for "Start in Performance Mode" would essentially be a duplicate of "Start Minimized".
If there is a difference, would the option to start in performance mode be a good addition to the client?

Edit: So far the changes had a negative effect on my side 
Hmm yes, the results are a bit unexpected.
Currently I have 2 (0.08%) rejected and 2,431 accepted in the block rounds. And I have 0 rejected and 545 accepted in the current shift.
I'm not sure what's causing some workers to get high stales still. I'm working on some ideas to lower stales further though.
Anyone who is running BitMinter client and haven't restarted it since we switched server, please try shutting it down and starting it back up. Then it will connect directly to the server in Germany, instead of going to the US and then through a tunnel to Germany. This could improve stales somewhat.

Woot! 7950s and 7970s are hitting the market, and as I had hoped, causing 58x0 cards to come on the market and prices to plummet. I just got a deal on a 5850 for 70 euro and Im negotiating a 5870 for ~90.
Now if only powersupplies would drop in price too. I am still using piles of older 500-700W PSUs, leftovers or psus that somehow found their way to my house, but despite generally being A-brands like antec, most of them cant even power 2 overclocked cards; this is getting tedious and the cable salad is not good for my zen/karma/whatever. Since I have several unused PCIe slots its all too tempting to spend my money on more cards, but meh.. a new PSU most come next now.
Im eyeing a Tagan 1000W for a good price, I know its not Antec, but does anyone have experience with that brand? I can buy it for like 1/3 the price of an equivalent Antec, and reviews dont seem bad at all.

Who the hell let me solve that block? 
EDIT: My 4890 solved that one. wierd.

Good. Now that you have solved the stale problem, perhaps you can tackle the block finding algorithm?
February 04, 2012, 06:13:32 AM
Is the new backend up ?
It wasn't when you asked, but it's running now.
First block change 3 stales. Second block change 0 stales. Looking good so far. Block rounds are of course affected by stales from the earlier backend still. But you can see the results of the new backend in the current shift, and faster response to your workers.
Ok, stales went up a bit more now, but still looking ok I guess.
Working on some more improvements.

Not a biggie I think, but use screen.
Yeah, I use screen all the time. For some reason I didn't with this thing and I thought it was only going to be needed a few minutes/hours. I put it inside a screen session now when I restarted it.
Found the problem too. When running with a security manager, the Java virtual machine caches DNS lookups forever. I didn't know that. Java WebStart applications always run with a security manager.
I will see about fixing this problem + fixing GCN support so AMD HD7970 runs properly fast (right now you must disable BFI_INT on those), then release an update for the BitMinter client.

What happened was that my overvoltage protection kicked in and cut the power to one of my computers. The shell with the tunnel was running on that computer, so the tunnel went too.
Not a biggie I think, but use screen. Then whatever session you are running over ssh wont close down if you close the shell.
simply run
Code:
screen ./yourscript
although just closing the shell will do the same, and not stop the script.
to reattach a screen
screen -r

The tunnel from old server to new went down this morning, causing quite a few workers to lose their connection to the pool. It's back up again now and workers seem to be reconnecting. Still through the old server. It's surprising that the old address is still being used so long after the switch in DNS. It appears BitMinter client is among them. I'll have to look into this problem and see if there is a way to force Java to look up hostnames anew.
What happened was that my overvoltage protection kicked in and cut the power to one of my computers. The shell with the tunnel was running on that computer, so the tunnel went too.
I think the tunnel was down 30-40 minutes? My apologies for the lost mining time for those affected.

Yay! All hail Dutchman, the slayer of the beast!
Doc, is that you? Random packet storm? Did that uncooperative block panic and go into self-defense mode?
Most likely it was the rate of requests going high enough to hit that bottleneck, causing everything to slow down and stales to occur.
I'm testing the new pool backend version now. I wanted to get it running tonight. But I'm going to let it run overnight to get some more testing on it.

Sticking with Doc...lol. DT will probably just solve another record block after this long one (what was it, like 4 mins or something?)
February 03, 2012, 12:26:07 PM
I trust Doc. Plus we have solved some blocks. I was talking more A1. They have solved no blocks. Say it goes on ANOTHER 3 million shares just by luck of the draw.. When they hit 7.5 million shares and the pool has NEVER solved any block true or not people are going to say the pool is broken.
Its a proportional pool. By the time it hits 7.5M shares , the payout of each share is 1/5th what you get elsewhere. Youd have to be nuts to mine there even if you trust the software.
February 03, 2012, 12:04:26 PM
Mind you, P4, the migration was a bit hasty...
What if Doc opted to take the combat reconnaisance approach to pool server bugs?
