[resolved] statsbox maintenance

Filed under: stats @ 04:30 UTC

We’ve taken statsbox temporarily offline for some minor system updates.  It should be back online before the next statsrun.  As usual, there will be no impact to stats or our proxy network during this downtime.

UPDATE: It is back online now and no problems were encountered during the maintenance.

[resolved] Unplanned webserver outage

Filed under: Uncategorized @ 02:45 UTC

We have just recovered from some unplanned outage of our main webserver that hosts www.distributed.net, blogs.distributed.net, bugs.distributed.net, and some of our other web interfaces. During this time our stats server and our keyserver network remained available and uninterrupted. We’re still investigating the cause, but we hope to minimize the impact of such problems in the future.

Project status for November 2011

Filed under: project status — Tags: @ 18:26 UTC

This past week we passed two nice milestones for our current projects:
On November 21, 2011 we passed 2% completion of RC5-72. We also recently passed 1000 days of OGR-27 since starting it in February 24, 2009.

Long time participant Andrew Hime posted a nice summary of the milestone statistics to our mailing list, so I’ll avoid repeating further details and just link to his post:
http://lists.distributed.net/pipermail/rc5/2011-November/042080.html

Today we also started recycling some of the old RC5-72 subspaces. This means that we’ll be sending out blocks that had initially been distributed as long ago as 2002 but had never been fully completed by any client. Since these subspaces are already mostly complete (generally about 85% to 95% finished), we’ll be able to move through these subspaces pretty quickly. Once we finish this pass of the uncompleted blocks, we’ll resume distribution of blocks from fresh subspaces again.

As always, thanks for your participation and support! ]:8)

[resolved] Stats website down temporarily

Filed under: stats @ 04:16 UTC

The statsbox is offline at the moment.  We’re hoping to get it back online tomorrow.  As always, no credit will be lost while it is inaccessible.  We’ll update this post with more details later.  Thanks! ]:8)

UPDATE: stats is back online and caught up.  Thanks for your patience!

Happy IPv6 day

Filed under: Uncategorized @ 23:52 UTC

distributed.net is one of the many websites participating in the International IPv6 day. On June 8 2011 starting at 00:00 UTC, we will have AAAA records listed in our DNS for www.distributed.net. Stats and our keyservers will not be affected during this event. For most people you should have no problems continuing to access our website. For further details, check out http://www.worldipv6day.org/

New 64-bit clients available for testing

Filed under: clients @ 15:50 UTC

We have new Windows and Solaris 64-bit pre-release clients available for early-adopter testing on http://www.distributed.net/Download_prerelease

The v2.9110.519 release includes two new 64-bit RC5-72 cores that offer an exciting speed improvement. We’ll be working to get the pre-release binaries available some additional platforms soon. As always, please report any bugs you find at http://bugs.distributed.net/

New source code updates

Filed under: clients @ 03:10 UTC

We’ve made a new public source code tarball available today.  Notably, this new tarball contains the ATI/AMD Stream cores for RC5-72, which are in the clients currently on our pre-release page.  You can download the new tarball from: http://www.distributed.net/Source

We now have also started making available our public CVS repositories on Github, to make it easier for contributors to access our source.  We’re going to be looking at what other parts of our infrastructure are suitable for releasing in the future.  You can find our Github organization here: https://github.com/dcti

Keep on crunching!  ]:8)

Wrapping up 2010

Filed under: project status @ 00:34 UTC

Dear friends,

With 2010 coming to an end, we thought this would be a good time to review the tremendous progress we’ve made this year, particularly on the RC5-72 front.

Modern video cards now typically include highly advanced parallel processors that can sometimes be used for general purpose computing. Although only certain types of tasks are currently suitable for GPU acceleration, we’ve found that RC5 falls happily in that category.

We began beta testing our first GPU-based clients for nVidia CUDA and ATI Stream in January and February 2009, respectively. Public testing of the GPU clients continued for about a year until we officially released both the CUDA and Stream clients in January 2010.

Adoption of the new GPU clients has been very successful throughout 2010, due in part to the folks at DNETC@Home. At this moment, about 86% of our incoming completed RC5-72 results come from Stream clients, 5% from CUDA, and 7% from traditional x86 processors.[1] Another exciting milestone is that the overall total results ever received for the RC5-72 project, results from Stream/Win32 are extremely close to surpassing those received from X86/Win32, despite the nearly 7 year lead before the official release of GPU clients.[2]

RC5-72 keyrate for 2009-2010

At the end of 2009, our overall RC5-72 project keyrate was about 250 GKeys/sec. Our current project rate is now about 1.5 TKeys/sec, or about 6 times faster than last year!

If we started RC5-56 right now (which took us 250 days in 1997), and found the key in the same place as last time, it would take us about 18 hours to complete. If we had to check the entire keyspace… it would be a little longer–perhaps 38 hours!

In the coming year, we hope to announce some other exciting developments which should continue to push the performance and awareness of distributed computing.

Happy Moo Year! ]:8)
