Collatz site is down

[NeoGen]

The collatz site has been down at least since yesterday. Either that or they changed the address, because I've been trying to see our stats there since last night and had no luck.

I haven't been on it for a long time, is this still the right web address?

It's been going down a lot lately. I quit running it because things were getting really unreliable. Since the weather is getting hot anyway I just decided to do the dark thing.

I also had to turn it off because of the heat. I hope to be back on it in the winter months if its still around and funds permit. I hope you have an enjoyable summer break from crunching Brucifer and join us again in the winter to help heat your house.

We definitely need to recruit more members from the southern hemisphere... :icon_lol:

Finally it's up again! :)


Internet Provider Testing
The power is back on, and the network is now up as well. For the next week or so, Collatz will be testing an alternate Internet provider. That means that the IP address has changed so you will need to restart your BOINC client in order to upload your results and get more work. I would appreciate any feedback as to how well the new connection is working or not working, whichever the case may be.

And now you have to restart BOINC to get Collatz to work... :icon_rolleyes:


Back to Comcast...
Collatz is now back on the old ISP which means the IP changed again and everyone gets to restart their BOINC client in order to upload or download work. Sorry about that. Why? After spending several hours both online and on the phone, it was determined that the new ISP and I defined "unlimited use" differently. Their definition is "about 5GB per month" which Collatz exceeded easily this past week, whereas my definition of unlimited use is... unlimited use. Silly me. The search for a stable, low cost ISP begins again...

And here we go again. Seems like every time I start crunching this project it craps out. Getting pretty rediculous. :-( Really ready to about just chuck this stuff.

2011-01-03: Collatz Conjecture - PBCAK (http://boinc.thesonntags.com/collatz/forum_thread.php?id=658)
There was a slight PBCAK while installing a new 42U rack today. Someone (me) bumped the power cord from the Collatz server which isn't even in the new rack. Due to the crash, it had disk errors while booting which took a little while to recover. Since the server was already down, I also took the time to optimize the database which was long overdue. Everything should be back to normal now.
...only it wasn't quite.
They'll be back up pretty quickly though.

They are down from 05:22 this morning (GMT+1), it's now 20:05 here, almost 15 hours later. In the meantime I have some 20 Collatz WUs piled up for upload. Luckely they they provide you with a long queue so I can wait for two more days if need be.
/ed.: 24:00 here (GMT+1) now and still down

not to many work units left over here

Hi Jason,

Good news and bad news: The good is that the server is up again, but the bad is that you cannot get new WUs at the moment. Use MilkyWay as fall-back (needs double precision GPU) or DNETC

[Jason1478963]

I might make it until it comes back online. I will keep milkyway in mind as i near the end of my work unit cache. I have tried dnetc in the past on a few GPU and may use that as a backup as well.

[Dirk Broer]

Good news: They are back
Bad news: New WUs take far longer and consume much more CPU as well (up to .67!)http://boinc.thesonntags.com/collatz/forum_thread.php?id=664

[Jason1478963]

I hope this isn't going to be the trend with boinc updates. I don't buy fast hardware to have it slowed down by buggy software!

Some new Collatz benchmarks:

HD 3850 3 hours
GTX 260 2 hours
HD 4770 1 hour

And the good news is that they have cured the CPU-hogging, it is now back to the old 0.01 level, which feels like a warm bath after the chilling 0.64 I suffered before.....
