Martin has probably not come to the most unbiased place for an answer
to his question, as I would expect most people here to believe that
GIMPS is indeed significant. I don't know of any other mathematical
search doing as much reliable work.

[EMAIL PROTECTED] used to be popular, but I haven't heard anything about it
for a while. It had many more participants, probably because looking
for extra-terrestrial life is sexier than looking for massive prime
numbers. However, I understand that their search lost popularity when
the server ran out of source data so kept on recycling already checked
data.

Google apparently offers something similar, related to protein folding
as a possible way to assist cancer research. I don't know how much CPU
power they have at their disposal. I believe Amazon are also either
looking at or have already implemented a similar project for their
users.

GIMPS currently harnesses power equivalent to over 1000 CRAY
supercomputers, which seems to me significant. See
http://www.mersenne.org/primenet/status.shtml for details. The search
has already found the ten largest Mersenne primes known, which is
already mathematically significant. See
http://primes.utm.edu/mersenne/index.html#known for details. No
Mersenne Prime has been discovered by any other person or group since
1996. Also, millions of candidates have been eliminated by being shown
to be composite, 118 of them by me.

Certainly GIMPS is significant, but I cannot comment on how it
compares with the others. It would be churlish to say that we have had
a result ten times but SETI haven't had any...
