Default Working on the 28,000,000-30,000,000 range

Just to let know to other people who are doing non server assigned work in this range.

Early November a lot of exponents lagging at the Double Check wavefront were released back into the pool. Unfortunatly it looks like many of them they were picked up again by another client that does not actually do any work. These exponents were reserved but never updated, are registered to ANONYMOUS, with no cpu name, no work recorded and with 'days to go' gone to a negative value.

The ones marked with an asterisk are seven exponents that I have started working on (extra P-1 and LL) and expect to finish before the 60 days period is over.

My guess is that it was CKDO that released them...he used to have lots in that range.
Not sure if it was on purpose though or due to a PC not reporting in for 60 days.

He released them on purpose. The range 26M to 28M has since been progressing fast. By then the unknown client that apparently was registered as having enough confidence and reliability to be assigned preferred exponents kicked in and seemingly abandonded them directly after.

How to start working P-1 for example 28550909?

First you look up this exponent at the report exponent page. If you want to do significant more P-1 work on the exponent you add the folling line to your worktodo.txt file

Pminus1=N/A,1,2,28550909,-1,600000,12000000

The last two values are B1 and B2. The values 1,2 and -1 must remain. You can omit this entire step if you are satisfied with the P-1 done on this exponent.

Next, look up the assignments page. It is here that you can see on which day the exponent was assigned, that it has never been updated and that as of today "the days to go" is at -21. When that value reaches -60 it will be reassigned by the server. So any work you do on that exponent has to be finished by then.

If you find a factor in the P-1 stage your work on this exponent is done. If not (most likely) and if you can complete the work in time add the following line to your worktodo.txt file

DoubleCheck=N/A,28550909,71,1

N/A means you assigned yourself this exponent, and the server did not. The value 71 is from the reported trial factoring done and the 1 means that P-1 has been done on this exponent already.

As you can see on the report a user by the name of Jerry Hallett did the factoring up to 71 only two days ago.

Your worktodo.txt file has an entry for each core of your processor. So if you have a four core machine, you can work on four exponents at the same time, just add the lines under each entry [Worker #1] up to [Worker #4]

Technically, DCing a candidate already assigned for DCing (or LLing similarly) is considered "poaching" by "the community" (or, at least, some of it; definitely those who are not lactose intolerant...).

On the other hand... A regular and dependable participant might wonder why the lowest untested candidate (once, without being suspect) has been allowed to linger for 1,144 days?

My four years old machine suddenly feels a lot older now. It does that assignment in 26 hours.

To avoid poaching I waited until the "days to go" went well into the negative. Together with all the other indicators it is reasonable safe to assume these assignments have been abandonded.

People who reserve exponents as "ANONYMOUS" and want to distinguish themselves could enhance the profile of their assignments by at least filling in a computername. That would keep me from considering an exponent.

When an assignment becomes the tail of DC or LL and indicates to need a lot more time to complete or give no reliable indication it is not unreasonable to have another computer doubling the work.

That does not guarantee 100% that he/she will not pick it up again.
