Hi all,

Indeed - we gladly offer compensation CPU time credit in PrimeNet's accounting
system for work lost to the v17 to v18.1 software upgrade. Please email
<mailto:[EMAIL PROTECTED]> with the exponent value and iteration or percent
complete at the time you upgraded from v17.
If your computers have contacted PrimeNet at any time since the first week of
April, any v17 clients will be clearly identified on your PrimeNet individual
account report. (Available at http://entropia.com/ips/accounts.html)
On a different subject:
On the heels of the probable find of the 38th Mersenne prime, I was undecided
upon about whether to ask all of you about a new prize pool for the next
Mersenne prime under 10M digits long. Obviously I've concluded, 'what the
heck' - I simply want your opinions. If you think the question is
inappropriate, please disregard.
GIMPS is certainly not about cash, and for those of you who offer your machine
time primarily for the value of GIMPS as an academic objective - and I believe
that is true for most of you - that is a very fine gift toward knowledge.
However we can't deny having seen cash prizes, in addition to this satisfaction,
make an observable difference in accelerating Mersenne number research results.
The $1500 I offered before the EFF contest began has since gone toward more
PrimeNet hardware. Between some GIMPSers, a new prize pool of $1111.11 has been
proposed (the radix is 10 :-) If you think it's worth a few (literally) of your
bucks to support their proposal, please let me know how much you would consider
'pledging' to a new GIMPS prize pool. A private response is fine.
No followup plans have been made - this will just give us some viability
measure. I'll later summarize it for the list.
Best regards,
scott
