Dear friends,

It is a great pleasure for us to announce that OGR-25p2 was fully
completed a just short while ago! We'll be providing some final
details regarding the mathematical results from the project
completion, as well as the details of our new project, later today.

With that in mind, I'd like to recommend that your clients are
switched over to RC5-72 as soon as is practical for you to do so. For
many of you, this is a non-issue, as your client will switch over
automatically. We will shortly be rolling out a new project which we
have been working on and hope that you can bear with us as we complete
our preparations.

We thank you for your continuing support.

Moo! ]:8)

The phat lady starts singing!!! :D

:cheers:

hopefully our crunched stubs count for today so we can :train: linux-de.org again :thumbs:

So no info about whether they will still be accepted OGR WUs for stats or not in there. I guess we will find out tonight if stats are processed again.

[Chuck]

Let us see which results are counted and which are not..... as it is still accepting my returned results and I would prefer to go find an official posting of said completion, which i will start doing now.



JUST taken from the D.net page.... last updated on the 13th.

Welcome!

Welcome to statsbox-iv, distributed.net's statistics server.

This server hosts the database which keeps track of statistics for the ongoing distributed.net projects.

Running progress and development announcements can be found in nugget's .plan, decibel's .plan and the announcements mailing list.

For those of you that have a morbid fascination about statsbox-iv itself, you can see a picture of the actual box.

Project Statistics

Here is a list of our projects that currently offer statistics:
Project Description Status
[Cow] RC5-72 RSA Labs' 72bit RC5 Encryption Challenge active
[Roo] OGR-24 Optimal Golomb Rulers completed
[Roo] OGR-25 Optimal Golomb Rulers active
[Cow] RC5-56 RSA Labs' 56bit RC5 Encryption Challenge completed
[Cow] RC5-64 RSA Labs' 64bit RC5 Encryption Challenge completed



Please note: OGR-25 ACTIVE.

[Nitrousine]

It's about time it's over! That took forever!


Now when does the next one begin? :D

[alpha]

Word in the official IRC channel is: soon. It sounds like OGR-26 is very likely and probably some other type of project is coming too..

edit: there's a new pre-release client up with the change "2.9101-507 new: all: Added OGR-NG contest"

edit 2: new .plan:

distributed.net is proud to announce the completion of OGR-25!

A little over eight years ago, distributed.net users undertook the
search for the optimal 25 mark Golomb Ruler. This year sees the
successful conclusion of that effort. We have proven conclusively by
the exhaustive search of all possible rulers that the previously
predicted 25-mark ruler is indeed the most optimal one.

The total length of the ruler is 480, with marks at positions: 0 12 29
39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396
431 459 467 480. (This ruler may alternatively be expressed in terms
of the distance between those positions, which is how dnetc displays
them: 12-17-10-33-19-...)

This shortest ruler was found by two independent computers. The
initial report was received on October 10th, 2007 and a second,
matching result was returned on March 24th, 2008. However it was not
until the final stub was returned and verified that we could rule out
the possibility of a still-shorter ruler. This final stub was returned
on October 24th, 2008 drawing to a close the complete search of all
possible stubs. Due to the nature of an exhaustive search,
distributed.net users have also proven that the above solution is
unique (the ruler's mirror notwithstanding).

To celebrate the successful end of yet another distributed.net project
all our contributors are invited for a drink...when we find a place
large enough to host the 124,387 people that participated in this
particular distributed effort. :)

As previously mentioned, a successful match of the shortest ruler was
found by two independent computers. We'll be sending those two users
some free distributed.net swag and shirts for their noteworthy
contributions to the project. We'll also be sending some swag to the
user that submitted that last confirmed stub. (At the time of writing,
we had not yet received permission from those three users regarding
the publication of their identities.)

Thank you all and keep those computers busy!

Just found this in a log file... must have missed by a fraction.


[Oct 25 23:20:38 UTC] OGR-P2: 1 packet (623.72 stats units) is in buff-out.ogf
[Oct 25 23:24:18 UTC] Network update is currently not available.
[Oct 25 23:34:08 UTC] The perproxy says: OGR-P2 is closed.


Would have been nice to add that one to our total. I should have been more attentive.



So, now we wait for the next team project?

[PCZ]

All my clients have now stopped..
pproxy says project is over.

OGRP2 section of the ini has completed status and the queue in has been deleted.

So the fat lady has sung,

Good job eveyone :thumbs:


edit:
It's a lot quieter in the house at the moment, CPU fans have slowed down and its getting chilly.
I'll give the machines a day of rest and consider options Monday.

[Chuck]

Pcz,
Same here..... but did we get 4th place back?????????

[Paratima]

Won't know till News @ Ten-ish. Have a drink, pill, or puff of whatever does it for you and cultivate patience. :D

[Paratima]

:umm: Nolo update-o.

[Chuck]

That was rather unfair, IMHO, to let us crunch for a whole day, initially grant the points crunched on the 25th and then yank them back, when all that was needed was verification of a SINGLE packet on another machine.

I have OGR-NG loaded and ready to go as soon as a proxy will permit it (it is the 507 'NG' update/project), but as I stated in another thread this is probably the best time to get the GPU lib ready for general purpose use. We've decided to work on both aspects.. a) ease of integration to a project a b) support for ATI/nVidia/etc and their product lines. My offer of assembling a larger team still stands. We are assembling a good crew and can then decide if perhaps WE (FDC) want a project of our own (?)

Anything else said re GPUs will be in the GPU thread. I just wish I had been able to help a few days sooner... it just might have made a difference as my trivial output is so very close to what it would have taken to win 4th place before the 24th end-of-project.... not a '25th cut everyone off'.

please forgive me if I am seem to be venting, I'm just disappointed and think we all (all d.net participants) deserve the credit for work done in the double check / exhaustive search double check.



At least the release candidate code 'rc' does acknowledge the OGR-NG project.... but I think we have better uses of our time and cpu power..... I personally don't wish to invest another 3001 days or (8 years ?) (as you all did)

If a poll is warranted, would someone please phrase it properly and place it in the appropriate place? I've been away too long to remember all the rules.


with deepest thanks to all for everything done to help me,
C.

That is too bad we didn't have that extra day to push into 3rd. The latest news.

Dear friends,

It is with great excitement that we announce our upcoming project to
find the Optimal Golomb Ruler with 26 marks. Optimal Golomb Rulers
have many applications including sensor placements for X-ray
crystallography and radio astronomy. Golomb rulers can also play a
significant role in combinatorics, coding theory and
communications. Dr. Golomb was one of the first to analyze them for
use in these areas.

New clients and proxies will be required to support the new project,
which we are calling "OGR-NG". The new clients will have version
2.9101.507 or higher. Clients with version numbers prior to this will
only be able to work on the RC5-72 project. Similarly, Personal Proxy
version 343 or higher is required.

Updated clients and proxies are being made available for early-adopter
testing at http://www.distributed.net/download/prerelease.php for many
major platforms. Builds for additional platforms are gradually being
produced and will be made available on that page as soon as
possible. If you do not feel comfortable helping with this
early-adopter testing and reporting bugs, then we recommend waiting
for a few days when we will move those clients to the official release
page. Not all of our public keyservers have finished upgrading to the
new version, so not all will have OGR-NG workunits yet. Stats for the
new project will also be launching in a couple of days. As with all of
our pre-release software, we encourage you to file bug reports for any
problems you find at http://bugs.distributed.net/

The OGR node rate for these new clients may appear to be slower than
those for the OGR-25p2 project. This isn't a cause for concern. The
effective search rate for the overall project is actually more
efficient as these new clients are using an improved algorithm. The
new algorithm is named FLEGE (Feiri-Levet Enhanced GARSP Engine). It
has been developed by Didier Levet and Michael Feiri over the course
of the past few months. We are especially grateful to them for this
Herculean effort. In technical terms, the number of elements in the
'choose lookup table' has been increased from 48K to 2M
elements. Although this will slightly increase the size of the dnetc
binary, this optimization will significantly reduce the number of
nodes that we have to search through, sometimes a node improvement of
ten-fold or more.

We estimate that OGR-26 will take much less time to complete than
OGR-25 and will probably be more similar to OGR-24, in terms of
computational effort. Beyond that, we're looking forward to OGR-27 and
OGR-28 because the current solutions to at least one of the two is
very likely not optimal. OGR-26 is on the way and must be done first
since higher-order rulers depend on the proven optimality of previous
ones.

We are grateful for your continuing support and enthusiasm.

[alpha]

Awesome! I'm up and crunching and I've upgraded my pproxy. Bok, can you let us know when your pproxy is updated so that we can begin using it for OGR-NG?

[Bok]

I don't see an updated proxyper for linux yet..

[PCZ]

Got the new pproxy running at home.
Clients all attached and got work OK :thumbs:

ppstats is working OK with it but the gnode numbers might be a bit off.
