distributed.net is proud to announce the completion of OGR-27!

It is almost five years ago to the day that we began on this exciting journey. Almost 20,000 of you joined us.. without whom, it would have been impossible.

We have proven conclusively by the exhaustive search of all possible rulers that the previously predicted 27-mark ruler is indeed the most optimal one. We were confident that we would find a more optimal ruler during this search, but it was not to be.

We expected it to take us seven years to complete this awesome task but thanks to your efforts recruiting your friends and co-workers to our effort and a little help from Moore’s Law, we did it in five.

Behind the scenes, we are getting ready to move over to our newest project: OGR-28. This is to discover the most optimal Golomb Ruler with 28 marks. We anticipate that it will take about as long as OGR-27 has. It has some features in common with OGR-27: some of the packets will be very large (up to 1500 Gnodes), and there are three stub spaces. We expect that the first two stub spaces will take about 90 days to complete. Ask me about that last part in a few months time. :)   Read more...

OGR-27 project almost completed... 

We’re very close being able to declare OGR-27 finished, but we have just a few more stubs remaining before final completion. The previous stubspaces 27.1, 27.2, and 27.3 are now officially complete.  We expect the last results in 27.4 to be received some time in the next two weeks, and then hope to begin sending out the first OGR-28 stubs within a few hours after that.

As a reminder, no new dnetc client binaries or configuration will be necessary since all existing OGR-27 (OGR-NG) clients are already capable of working on OGR-28 once we begin sending out those workunits.

Look forward to us making another blog post containing some final statistics about OGR-27 within the next two weeks!

November Update:

We have completed over 96% of the work and are now close to wrapping up OGR-27. Some of you may have noticed some difficulty getting OGR packets earlier today, due to our need to begin recycling of the remaining stubs. As I write this, there are about 20 million left that need working on. It is likely that you may experience difficulty occasionally in the coming weeks when hoping to collect OGR stubs to process. This is due to the master key server being unable to speak and chew at the same time!

If you have a long memory, you may remember a note from me about needing to complete one more verification pass on a small number of stubs, about 2.2% of the total, that had been processed by buggy client versions. Now is the time! Some of you are already working on these stubs. One of our core contributors “Stream” has calculated that it will take us about 3 weeks at our current average (400 Gnode/sec) to complete the verification of the earlier stub spaces.

Today we also mark the 4000th day that we have been working on the RC5-72 project. We passed 3% completion only a few weeks ago and continue to make steady progress.

As ever, you can catch up with us in #distributed on IRC (irc.distributed.net).

Do you have an Android device on your desk languishing on charge while
you are asleep? Perhaps you have a shiny new tablet? It is now
possible to run OGR on it! Late to the dance, I know…

It is running using the BOINC Wrapper technology. You can download the
BOINC app from Google Play or the ‘Market’ app (depending on your OS
version.) Just attach it to the yoyo@home project:
http://www.rechenkraft.net/yoyo/ and follow the instructions.

Moo! :)

It has been a while since I have posted any updates to my blog here. I’ve even had a few notes asking if we’re still working on our projects. I can assure you that we are.

We’re going full speed ahead on OGR. My favourite web page at the moment is http://stats.distributed.net/project/ogr_status.php?project_id=27 , which shows in detail how many stubs we have left to process until OGR-27 is complete.

At the same time, we’re still working on RC5-72; where we have nearly completed 3% of the total work space.  We released new client software over the summer which works around the incompatibility we had with AMD 7xxx series graphics cards. The keyrate history graphs for RC5-72 and OGR (http://stats.distributed.net/keyrate.php?project_id=27 and http://stats.distributed.net/keyrate.php?project_id=8) are back online after a hardware failure.

I hope to have some more updates for you very soon. :)

Moo!
