I got this error on my GIMPS client (version 20.4.1) x86: Error 11: exponent already tested I'm testing exponent 8277083 and I'm about 45% done. Every other time I've checked in, it was OK. Now I get this error message and the exponent is gone from my GIMPS user status page. Yet, the client continues to work on it. I HOPE I DIDN'T WASTE MY CPU CYCLES. Somehow, the exponent got cleared. It's in the cleared.txt document. (The cleared exponents page). It was cleared July 19th by a user named "Floris". Thanks Floris. I didn't know the server was checking out multiple exponents. Could someone explain what has happened, and can someone tell me how to fix my client to resolve this issue?? - -Dennis ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com _________________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.exu.ilstu.edu/mersenne/faq-mers.txt ------------------------------ Date: 20 Jul 2000 00:09:20 -0400 From: "Robert Deininger" <[EMAIL PROTECTED]> Subject: Re: Mersenne: Error 11: exponent already tested!?!

I have saved some of the hourly status and cleared reports, and I think I see what happened. On 13-May-2000: 8277083 64 4126527 105.0 -12.1 42.9 16-Apr-00 19:40 29-Jan-00 22:24 floris Vincent This exponent was assigned to floris on 29-Jan-2000. On 25-Jun-2000: 8277083 64 4126527 148.0 -55.1 -0.1 16-Apr-00 19:40 29-Jan-00 22:24 floris Vincent The exponent had just expired, but is still assigned to floris. On 26-Jun-2000: 8277083 64 0.7 34.5 66.5 26-Jun-00 10:24 26-Jun-00 06:44 timbit home1 The exponent has been re-assigned to you, and you didn't realize it was previously assigned to floris. floris/Vincent continued to work on the exponent, finished the LL test in the last day or two, and checked in the result. I don't know why the server accepted the result, since the exponent was no longer assigned to floris. I think this was an error. Probably you should continue the LL test and get credit for double checking. I guess you should contant the primenet administrator and ask for some manual intervention to make sure your work isn't wasted. Alas, it appears the first LL test has been completed and checked in.

If the assignment is checked in as double check already (see the cleared assignments report) then you can remove the assignment from your worktodo.ini file, as when the assignment is double checked already an extra result will not be accepted.

I realize there are participants who will undergo "agonies similar to giving birth" unless ALL exponents through xxxxxxx are checked by such-and-such a date. Nevertheless, as the exponents being worked on start taking longer and longer on any given machine, could we PLEASE refocus GIMPS recordkeeping on the 'humane' aspect of the effort, rather than on the 'treadmill' aspect ? Because the GIMPS expiration limit has stayed at 60 days (rather than increasing with the exponents) I no longer try to run LL tests with my K6-III machine. [I run offline. If I am forced to "check in" by a given date even though I have not finished, for me it is simpler to just decline to participate.] The material I quoted from Robert Deininger appears to me to indicate that somebody who was working on an exponent failed to "check in" for at least 70 days. The exponent got assigned to a second person, who got upset when the original person suddenly completed his LL test. Wouldn't it be more 'humane' to wait a bit (i.e., to not 'expire' assignments after 70 days) ? Will the project truly suffer if "seemingly abandoned" exponents are NOT reassigned on a 'treadmill' schedule ? mikus _________________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.exu.ilstu.edu/mersenne/faq-mers.txt ------------------------------ Date: Thu, 20 Jul 2000 14:28:13 +0100 From: [EMAIL PROTECTED] Subject: RE: Mersenne: Error 11: exponent already tested!?! Another enhancement would be to add the functionality to force a checkin with the server. Currently I have found the only way to do this is to alter the number of hours per day field. This is fairly minor compared to the problem of duplicated effort mentioned below but may elevate the problem slightly.

If you complete the exponent it will serve as a valid double-check. If you do not wish to complete the exponent I'll bet someone on the list will be glad to take your Pnnnnnnn and complete the test. >Could someone explain what has happened, and can someone tell me how to >fix my client to resolve this issue?? If Floris was using the automatic method as most people are, then he did not connect to the Internet for a 60 day period. That is, after 28 days the program will start trying to contact the server saying "I'm still working on Mnnnnnnn". The server won't release the exponent until 88 days after testing began. This algorithm seems to work well as the recycle rate is rather low. There is a downside to increasing the 60 day period to a higher value. If it takes longer to recycle exponents, there will be more "holes" and the server will have to hand out larger exponents. If Floris was using the manual method, then he neglected to use the manual web pages to extend his assignment. The suggestion that the manual web pages default to a value higher than 60 days is reasonable. I'll contact the primenet guys to see if they can change it.
