SETI@home Weekly Update

June 2, 2000 - Dan Knight

Congratulations to Team Art Bell, the first club team to pass the one million mark.

Eight of the top 25 teams changed places this week.

We are color coding changes: red text for hot teams that have climbed in the standings, blue for those that have cooled and dropped in the standings.

Team 6100, the slowest part of Team Mac Observer (it's only for unaccelerated Power Mac 6100s) has grown to eight members. We've now completed 36 units and are averaging 76-77 hours per unit. That means each computer can over two units per week, assuming they are running SETI@home full time (mine is). It's not a huge contribution to the effort, but we're adding about 2 units per day.

Key tools in this anaysis are the SETI@home team statistics page, the SETI Checker program (which visually graphs recent weeks for team performance), and Dave's Stats, which cover the whole SETI@home project, as well as the team he's part of, The Knights Who Say Ni!

In the following analysis, data in the second column comes from the SETI statistics page. Information in the third column comes from my analysis and Dave's Stats, which is my source for the average recent work units per day (because the page has not been since Wednesday, we're using Wednesday's averages). Note that this is a volatile figure which can change a fair bit from day to day, especially as members join or leave a team and bring their work units with them.

You can also view weekly reports from April 14, April 21, April 28, May 5, May 12, May 19, and May 26.

This week, nothing below the Top 25 looks to be moving into the Top 20 in the near future.

Possible future contenders for Top 25 spots:

• Team EDGE is currently at 27. Dave projects them at 19 within a month, which may be a bit optimistic. Reaching the Top 25 should be no problem.
• Forum Hardware.FR Team, 32, will reach 21, according to Dave's stats. It's a fairly new team, but they do look destined for the Top 25.

Remember all this is based on a fairly simple mathematical model that is thrown off by significant defections or additions to a team's stats. Dave and I have been corresponding to develop a model that will create more reliable predictions.

That's how the top team standings look this week on the SETI@home club team page. Come back next Friday for another update. (And if you'd like to join a team, I'd like to see you join Team Mac Observer.)
