SETI@home Weekly Update
May 19, 2000
Dan Knight
SETI@home turned one year old on Wednesday, May 11. As of this morning, there are 2,011,678 users. Between us we have completed over 122 million work units. We are currently averaging 15.96 TeraFLOPs/sec.
Macs have contributed almost 10% of the total at 12.1 million units, 11.3 million of those under the Mac OS and 0.8 million using other operating systems.
Team Art Bell should pass the one million mark by the end of the month. They will be the first club team to do so, although three corporate teams (SGI, Sun, and Compaq) have already done so.
Looking at daily units submitted (on Dave's SETI Stats), it seems the SETI server was down all day Tuesday (5/16) as well as parts of the 13th, 14th, and 17th. Because of this, most teams have much lower average units per day than usual.
Team 6100, the slowest part of Team Mac Observer (it's only for unaccelerated Power Mac 6100s) has grown to six members. We've already completed 15 units and are averaging about 72 hours per unit. That means each computer can do about 2.3 units per week, assuming they are running SETI@home full time (mine is). It's not a huge contribution to the effort, but does add about 2 units per day.
We're now 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, May 5, and May 12.

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:
- Hardware Central is currently at 45 and averageing 3,433 units per day. Dave projects them at 16 within a month, but they are only two weeks old, so the numbers are high due to a lot of new members. However, they should climb rapidly until they hit about 20th place.
- Cassieopeia Seti Group, 32 and averaging 2,092 units per day, is only three weeks old and really crunching work units. Daves stats have them reaching 21 in mid-June, but it's hard to predict how a new team will fare in the long run. If they maintain their high average, they will be serious competition.
- Forum Hardware.FR Team, 39 with an average of 1,442 units per day, will reach 28, according to Dave's stats. Again, the team is only three weeks old, so their average units per day will probably settle somewhat. Still, they are climbing rapidly.
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 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.)
