 | SETI@home Weekly UpdateMay 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

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.)
