Probably not too terribly long. That's maybe what, five gigs of email,
total? In reality, they need not even send quite that much, as they
only need to make one connection to, for example, Yahoo.com, just
defining multiple recipients. Ditto with aol.com, earthlink.com, etc.
You could probably fit 95% of that population in 150 mail servers.

How will the S@h server cope with 4,723,933 dowmloads?

It probably won't have to. Out of those 4.7 million registered users,
how many are active participants today? Out of those active
participants today, how many are going to switch away from SETI@Home and
over to BOINC right away?

I think they are smart enough to space it out over weeks or months.
Notify people in batches small enough to handle.

Eeeeek, I can't stand it! Someone please tell me what is a
cobblestone. Have mercy, I'm going mad.

a cobblestone is something you can get hit on the head with
on a dark night in an alley in foggy London...

Sorry, couldn't resist ;o)

Subject: *Admin* ~ What happens to credits??
Message 18 of 43

Well they might be converted into Cobblestones...

Computation credit
Each project gives you credit for the computations your computers performs for
the project. These credits are used to generate web-site "leaderboards" showing
individuals, teams, and categories (countries, CPU types, etc.) ranked by
credit.

BOINC's credit system is based on a "reference computer" that does

1 billion floating-point multiply/adds per second
1 billion integer multiply/adds per second
4 billion bytes per second of traffic to and from main memory (sequential, half
reads and half writes)
BOINC's unit of credit, the Cobblestone, is one day of CPU time on the
reference computer. (Credit should ideally reflect network transfer and disk
storage as well as computation. But it's hard to verify these activities, so
for now they aren't included.)
Each project maintains two types of credit:

Total credit: The total number of Cobblestones performed.
Recent average credit: The average number of Cobblestones per day performed
recently. This average decreases by a factor of two every week.
Both types of credit (total and recent average) are maintained for each user
and host.
