distributed.net staff keep (relatively) up-to-date logs of their activities in .plan files. These were traditionally available via finger, but we've put them on the web for easier consumption.
Several new client versions were promoted to released status today, for a detailed list consult the list of client updates by release date. As always, updating to a more recent client release brings with it performance and usability improvements as well as bug fixes. Consult the most recent changelog for a list of the changes that have occurred. (Check the changelog included with each client for an exact list of changes included.)
For those who want to help with testing the latest and greatest, please peruse the list of prerelease clients available.
Thanks all for the contributions and happy holidays.
The mediawiki backend on www.distributed.net has been upgraded to the latest version. Let us know if you see any breakage.
After several weeks of anticipation, we’ve finished deploying our new stats servers and have fully transferred operations to them. The two new machines (standard and deviation) should be able to provide us with sufficient capacity and reliability for the foreseeable future. You can check out a picture of standard and deviation in our photo gallery. Full hardware specs on our current and past servers are also listed on the statsbox FAQ page. Our old server, fritz, has been physically relocated offsite and is awaiting a disk wipe before we decide its final fate.
Stats should again be available at http://stats.distributed.net/ No loss of data occurred during this server transition.
We’d also like to thank Midas Networks in Austin, Texas for continuing to provide excellent hosting services to us.
Thanks for your attention!
We’ve taken our stats server temporarily offline while we do the final cut-over to our new server hardware. If all goes well, the upgrade should be complete in time for today’s statsrun.
There was a brief interruption in the distribution of RC5-72 workunits earlier today, however the problem has been fixed and clients should be again receiving workunits. OGR-27 was completely unaffected during this time. Additionally, RC5-72 results continued to be accepted without interruption.
The problem was caused by our migration to some new webserver hardware (unrelated to the new stats servers), which disrupted some of our alert monitoring systems.
Keep on crunching!
We’ve temporarily put our stats server into “read-only” mode, which means that you’ll be able to view your current stats (and they will continue to be updated daily) but you won’t be able to make any changes to your user account or team. As usual, no client work will be affected during this period.
This is being done to prepare for switchover to new hardware that will replace our aging stats server some time next week. Read-only mode allows us to make and restore database backups without losing any user-made edits. We’ll make another announcement once the new hardware is fully deployed.
If you’re curious, some details about the new stats hardware are listed on our FAQ page.
So, stats hit a milestone of sorts. We’re got a team that has now done 2^63 keys in rc5. This has overflowed the column that it was stored in.
The temporary solution is to increase these columns to NUMERIC(25), which is 10^25. This gives us over a million times more storage until we get a more “correct” solution, which is to store stats units in the database. But that requires more work, and we’re looking to get things up as quickly as possible.
We apologize for the downtime but we didn’t realize how good you guys are!
It seems that we’ve encountered an unexpected milestone in the our RC5-72 project’s status! Last night’s stats processing hit a data overflow error in one of the team database columns.
We will be making some schema changes to one of the backend team tables and hope to have stats processing back online later today. Once we’re done, stats should again properly reflect all received results.
Keep on crunching!
Stats server is back online and fully caught up after the outage. We’re still running on reduced redundancy on the power supplies, however.
It is probably time to consider a complete replacement of this machine, since it has been running for more than six years (April 2004). It has also recently been suffering from regular failures on one of its RAID controller ports, regardless of the drive connected to it.
As a reference, the current stats hardware is described at the top of http://faq.distributed.net/?file=63
We’ll be investigating our resources and options over the next few days and hopefully be able to begin the replacement process soon.
Thanks for your support!
One of the three power supplies in our stats server has failed again, causing it to be unstable while operating on the remaining units. We’re in the process of trying to get the failed unit replaced, but it may take a few days.
Until then, all results sent by dnetc clients will be saved by our keyservers and will be reflected once the stats server is brought back online. Thanks for your support!
