We have started removing database records for results that were completed more than 7 days ago. This will limit the size of the workunit and result tables in our database. Happy holidays!

December 27, 2004
We are experimenting with redundancy parameters. We will continue to send 3 copies of each workunit, but will validate results and grant credit when 2 (rather than 3) of them are returned. This should result in faster validation.

Well looks like they deceided to go back to 3 for validation, but will now send out 4 copies of the WU now instead of the original 3.

More on redundancy parameters. After some discussion we have decided to send out 4 copies of each workunit and continue with a quorum of 3 for validation. Validation should still proceed at a good pace because a single result in error will not mean distributing an additional workunit copy (and waiting for it's result) in order to reach a quorum.

i guess what ever works - as long as i can download WU i am happy

Looks like they have received the new hardware and are converting to improve the capacity of Seti Boinc. There is a slowdown with getting credits but this too shall pass.

We're hastily getting two new big servers on line. One will be the new BOINC database server. Our current server is maxed out at 2 old CPUs and 2 GB RAM. This new server will start with 2 CPUs that are 5 times faster and 8 GB RAM. Plus it has the ability to grow by 2 more CPUs and double the RAM if demand is high. As well, attached to it will be a hardware RAID for much faster disk I/O. The current server will then become the replica server. We need to get this working in order to keep up with increased demand as users migrate from classic SETI@home to BOINC.

The other server a Sun E3500 similar to our current E3500 which holds the master database (where all the scientific results are stored after they are validated). The storage on the current database is slow, bulky, and almost full. We will put much larger, more efficient disk arrays on the new E3500 and then transfer the database to it. This will vastly improve the speed of our back-end scientific analysis.

Hopefully they goof something up (not too bad though...

) so that Classic can run another four weeks or so...

15k here I come! :burn:
