Project OGR

The OGR project restarted with new clients on Thursday July 13, 2000 around 22:00 UTC. The first pass of OGR-24 has been completed and distribution of OGR-25 was started on August 1, 2000. The verification second pass of the OGR-24 stubspace is currently being done in parallel with OGR-25 distribution.

Although OGR code has been present in the dnetc Official Clients since version v2.8002.446, no blocks will be accepted from versions prior to v2.8009.460. We ask that you update your clients to v2.8009.460 or higher. These clients have been available for some time now and you should take the time to upgrade as many systems as you can.

Even if you don't plan on participating in the OGR projects, you will want to upgrade your clients because of major network and buffer-management improvements. Check out the changelog document for a complete list of changes.

In the first year of running the OGR-25 project has attracted around 55 000 participants with three to four thousand participants reporting each day. The project is approaching 6000 participating teams of which almost 1000 are active each day. So far we have tested over 7 000 000 000 Gnodes of OGR-25 stubs.

You can monitor your OGR progress at OGR stats. For information on changes to stats see the following document.

The Advertising Banner Area has been updated and obsolete banners have been removed. While we have many banners for the RC5-64 project, project OGR banners are currently lacking and contributions of these will be particularly welcome.

Stats code available as open source

The stats code is now open source and is available on GitHub. The database software used to keep track of work done and generate reports is Postgres.
