Default How does "diamonddave" operate?

I've been poking around in the status.txt and cleared.txt files (up-to-the-hour Assigned and Cleared exponents from Primenet).

I've noticed user diamonddave apparently takes over other users' exponents in the very low ranges. Not in the sense of grabbing expired exponents, but literally taking over the original assignment, with original assignment date and current iteration and update date.

Some examples, first from Sept 06 00:00 UTC status.txt (assigned exponents):

Code:
 8946493 D*  64             120.4  14.5  57.5  02-Sep-03 13:57  08-May-03 14:56  JC             DAU1

Also, diamonddave hardly ever seems to return any valid results in cleared.txt. His assignments sometimes get deleted and assigned to another user, or sometimes end up being completed by other users.

From Sep 06 00:00 UTC status.txt (assigned exponents):

Code:
 8826407 D   64              30.8   2.3  57.3  30-Aug-03 03:57  06-Aug-03 06:14  diamonddave    finrad.dc

Then from Sep 08 15:00 UTC status.txt (assigned exponents):

And from Sep 08 16:00 UTC cleared.txt (cleared exponents):

Code:

Also from Sep 08 16:00 UTC cleared.txt (cleared exponents), the only entries for diamonddave are some blank(!) residues and one valid factor.

Code:

This only occurs in the 8M range for doublechecks, so I assume this is part of some strategy to clear up straggling exponents? I'm just curious.

Sorry, this should say: the update date does change, and is set to a recent value.

Some of these aren't even straggling exponents. Particularly 8968339, run for only 16 days and well on its way to completion (iteration=5178566).

Presumably Oerwin/camel will shortly get an Error 11 when he tries to report the result?

There are a bunch of things happening here. Presumably diamonddave is "poaching" exploiting a bug in Primenet that those in the know have been aware of for sometime. With this exploit the updated date changes but the expiry and days to go dates do not when the exponent in magically reassigned to the new person.

As a result when the exponent expires it can be picked up by someone else pretty soon. Also, the original assignee can return the result before diamondave gets a chance. I doubt that diamondave is returning the results under his/her own name. You might want to track his/her assignments for some time and see who eventually returns those results.

Finally, if you have started working on an exponent and it gets reassigned to someone, prime95 does not stop working on that exponent and you do eventually return a result which is accepted by Primenet and the exponent moves from the assigned to cleared list. That is how most poachers operate as all the results do get accepted even if the exponent was not assigned to you.

PS: Personal disclosure: I use the account New_Boy/garo_q to reserve expiring exponents which I shift once/twice a week to my Team_Prime_Rib account. The reason i do this is that TPR cannot unreserve exponents due to a change we requested when a bad guy unreserved most of our exponents back in Jan 2002.

BTW, from your last post the results for exponents 8826407 and 8888293 were both returned by their orginal owners. I have an ols status.txt file from 08/06 which shows both being assigned to these accounts.

In case anyone cares, here's the complete list of assigned exponents for which the username changed between Sep 6 and Sep 8 but the assigned date did not. In other words, exponents transfered between users without an expiry having taken place in the meantime.

Mostly it seems to be users changing their own user-ids and such. We also have dswanson taking a bunch of exponents from "contech", which he presumably controls. But there is only one user (diamonddave) who seems to have taken exponents from multiple other users.


Apologies for the large size. Unfortunately the [ code ] tag can't be combined with the [ size ] tag to create small fixed-font text.

These are the "before" and "after"

GP2 is correct: The exponents transferred from contech to dswanson are by agreement. A few years ago shaneamy completed the first-time LL on the listed exponents. When these same exponents were recently released for doublechecks, he reserved them again under the contech name, an account he and I use for exchanging exponents. He did this to ensure that the doublechecks would be completed quickly, which I'm now doing. contech still holds 5 exponents; you'll soon see those transfer to dswanson, too.

Those, like GP2, who have been closely monitoring assignments may have noticed that over its history contech has had every single one of its approximately 50 exponents "poached" by either shaneamy or dswanson. contech has never finished a single exponent.

Just another example, like garo's, that there can be legitimate and perfectly honest reasons for taking advantage of the Primenet bug.

Don't know if this has anything to do with what's written above, but here's a message that Diamonddave a couple of years back wrote to the mersenne mailing list.

Perhaps there should be a warning, not to poach exponent at the top of the
"Test status, assignment report". I feel I am to blame, because it must look
to the poachers like all those small exponent are reassigned to the same
guy. If they look closely at my assignment they will see that 99% of them
had been assigned at ~6:03 PST, that's when Primenet release overdue
exponent back into the available pool.
And with the 90 days rule there is no reason to poach.

What, you are not up at that hour! well here is my secret (only available on
NT system with 24h access to the Net).

make 2 CMD file

part1.cmd :
d:
cd Mersenne
ren worktodo.ini *.tmp
copy start.ini worktodo.ini

part2.cmd :
d:
cd Mersenne
type worktodo.ini >> worktodo.tmp
del worktodo.ini
ren worktodo.tmp *.ini

modify your prime.ini ( look in the documentation for the Time variable,
because it's quite complex):
DaysOfWork=20
Time=1-7/0:00-2:00,1-7/2:04-2:15,1-7/2:20-24:00

start part1.cmd with the AT command at 6:03 PST
start part2.cmd with the AT command at 6:18 PST

And now the hard and real important part:

monitor your Account report EVERY DAY (I can't stress this enough, because
EVERY DAY 4-5 new exponent are going to be assigned to you, if you are only
able to monitor your account on the weekend modify the part* schedule and
Time setting, to fit your need) and keep ONLY 60 days of work for your
computer, use the release form on PrimeNet to release high exponent that you
can't complete in 60 Days. and reorder your assignment so that the smallest
exponent are finished first.

I've been doing this for about 6 months and let me tell you that it's quite
tedious, there is NEVER a day off :)

regards

David Campeau a.k.a "DiamondDave"

P.S: this can be used for any type of assignment! there is no reason why it
should be used ONLY on double-checking (modify your AT command and prime.ini
accordingly).

P.P.S: if you plan on doing this, DON'T quit in the middle w/o removing your
part1 & part2 from the scheduled task,
