Current "RAC" (Recent Average Credit) by the team. Total Members are numbers reported by the BOINC Project. Members w/o Beacon are members of the team activly running this project, but has yet to advertise their CPID to the Gridcoin Network.

Team Hosts count are number of hosts that are connected to team members. Anonymous hosts can not be counted to the team.

Server upgrade planned for Dec 19

Hi everyone, we're upgrading the server to a new machine on Dec 19. Expect intermittent outages which could last as long as 24 hours. No action is needed from users during the upgrade. More workunits will be on the way shortly thereafter. Thanks!

Preparation for a server upgrade

Dear users, Over the next couple of weeks, we will be moving the Cosmology@Home server to a newer machine. No action is needed from you, and we hope to do so with minimal down time. This will solve lots of the work generation and validation problems the site has had over the last several months. It will also set us up to debut some new science applications which we have been working on and thinking about. For now, we are letting the work queue get emptied out. Once that is done (it already is for camb_legacy), we will move forward and keep you updated. Thanks for your continued support!

Recent outage explanation

Hi all, Over the last week we suffered a database corruption due to some disk errors. I've spent the last several days recovering the database from backups and from the corrupted files. Unfortunately, records of workunits from the last several weeks were lost, which means you will not receive credit for any of these jobs. I greatly apologize for this, and we've taken steps to make sure this doesn't happen again. The good news is that this was the only thing which could not be recovered, everything else is fine. We're continuing to monitor things as the server comes back online, please report any problems you may find here. Marius

Based on all hosts for this project (anonymous hosts included) the following table displays some estimated projected RAC for a specific architecture. The data can be incorrect, incomplete and/or very inaccurate since we have no way to verify how much the host runs the specific project. This is based on architectures that has checked in once the last week with at least 5 hosts.

Max RAC: The highest RAC score found for a single host.

Please note that this is NOT a mining calculator, but rather a way to find hosts that can perform well on the project based on what other uses.
