What is the largest individual effort currently under way?
 
Of course, we all know about the team efforts of Curtisc and Team_Prime_Rib, but what is currently the largest INDIVIDUAL effort under way?

As for my miniscule contribution, I have two P-4 systems (2.2GHz & 2.6GHz) and a Celeron (2.6GHz) working on it.

Depends how you define individual, I guess. Not all the computers I use are owned by me, but I have set up everything and written all the scripts I use to control my farm. Every participating computer is controlled by me, by permission of course.

A few numbers from my report:
[PRE]
Intel Pentium III : 113
AMD Athlon : 1
Intel Pentium II : 3
Intel Celeron : 1
Intel Pentium : 2
Unspecified type : 133
---------------------- -------
TOTAL, uniquely named : 255
[/PRE]
Most of them are only running mprime when no users are logged in. Some are only running at night. I also use some dual G5s and 4 of 64 Itanium2 CPUs on a HP SuperDome with 0 priority through a batch system.

I think individual would mean not in a team.

That would be me, but the (apparently) two man team C. Cooper / S. Boone has almost four times my CPU time. At least one of them is producing very much more than I am! There is also another two man team ahead of me (Marc Getty / Phil Fizur).

I've contributed 39.336 CPU years. I think that is 4.09 * 10^16 floating point operations. Is that right?

Damn! And I thought my operation was of a pretty decent size:

I convinced a friend to put his Athlon to good use, so I guess technically that's not all me. I've also had a P100, a P266, and a K6-2 500 in the past. That also doesn't count my dual-Athlon, which is in the shop at the moment...

I took this thread to mean my machines that I use everyday as I see fit.
However, I have given to family members most of my machines.
The conditions are that they do not run a screen saver and they run prime95 24x7. Everything else is fine.
If we include all that . . .

Intel Pentium III : 1
AMD Athlon : 1

You just might be addicted to GIMPS if...

#72: You managed to build a P4 machine for all your friends with some "Special Software included at no charge!" :grin:

You've got to start somewhere. I started with my own 486 and by asking if I could use some SGI Indys in a computer lab at my university during times when the lab was closed. Then I added a few Sun machines and a couple of Windows machines, and then idle time on an IBM SP/2, then more labs, and then more and more Linux machines which have replaced the old Indys and Suns.

There are negative sides to large operations. My current Primenet Report is 2676 lines long. At the end it says:
[PRE]
Factored composite : 69
Lucas-Lehmer composite: 1028
Double-checked LL : 96
---------------------- -------
TOTAL : 1193
[/PRE]
Kind of hard to get an overview. But no primes yet...

I started with one AMD K6-II 500. Then I added my old P266MMX laptop. After that I dug my really old P100 out of the basement and used that. Eventually I got around to building more modern PCs though... :grin:

Actually, the fact that I have a dual-Athlon is a reflection of the fact that I'm a GIMPS addict. I ordered it that way specifically so I would have an extra processor that could be totally dedicated to Prime95.

I take the more conservative interpretation of the question meaning "How many computers do you run at home?" (since I presently only run three computers at other places). So I have six P4's (1.80A, 2.40, 2.40B, 2.40B, 2.40C, 2.40C) and one Pentium M (Centrino) laptop.
