SETI@home Weekly Update

May 12, 2000 - Dan Knight

I just noticed that Team Art Bell should pass the one million mark somewhere around May 22. Very impressive!

The "fun" addition to Team Mac Observer last week was Team 6100, for unaccelerated Power Mac 6100s. Ten of these roughly equals a G4/400. ;-) At this point, we have five 6100 users, who have contributed a total of eight units. (Working flat out, a 6100 can do about 2.8 units per week.)

Beginning this week I'm 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. There are three places where teams have swapped positions in the standings over the past week.

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. 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, and May 5.

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:

  • Scarfy, currently at 27, has a very sporadic growth curve and could enter the Top 25 in the coming week. Or not. Very hard to predict based on their erratic performance, but they averaged 1,494 units per day this week.
  • Cassieopeia Seti Group, #38, is only a few weeks old and really crunching work units. It's hard to predict how a new team will fare in the long run, but this one looks promising.
  • workers@pse, #51, is about one week younger than the Cassieopeia team and has a very similar growth curve.

With new teams is a question of momentum: can they follow through on the initial buildup. Most of the time the answer is no.

That's how the top team standings look this week on the SETI@home 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.) LEM
