We have three networked (peer to peer) computers running
Seti@Home.

The network includes a Linksys Printserver, an Assante Router, and a Linksys hub.
- No machine is dedicated exclusively to Seti@Home
- All machines are used for email, word processing, games,
educational software, web design and, of course, web
browsing. The games place a high demand on the cpu's and
slow down Seti workunit processing.
- The Set@Home
windows clients are set to run all of the time on all three machines, under the
premise that even slow processing is better than no
processing.
- Our current average processing time per work unit for the P233's is 46
hours (no additional cpu load) up to 54 hours (additional
heavy cpu load). The P100 averages 93 hours per work unit.
- Machines are on 16 - 24 hours a day (except during
electrical storms, when they are shut down and
disconnected from the power and telephone lines.)
- Due to Server Bandwidth at UCB, we are now running Seti Queue, which enables us to cache work units and connect to the Seti@Home server only during off-peak hours.
- The two P233's were originally built by ST Monforte
Robotics as Pentium 90's. Both have undgone
extensive upgrading (one has only the original case,
power supply and floppy drive and the other has only the
original case and floppy drive).
- Both upgrades began with a hard
drive replacement and ended with.... (Murphy's law?)
- The P100 was built by Dell.
