ERROR 17: Exponent not assigned to this computer.

Hello,

I have mprime running on several Linux machines. One of them is a Laptop, and thus it's not frequently running because it drains the battery and makes noise to occupy the CPU.

So I paused a few months, and now when starting it outputs the above message, while nevertheless continuing computations. It further says:

The FAQ at http://www.entropia.com/ips/faq.html may have more information.

but that link is outdated.

What can I do? I wouldn't want to continue work on my current mersenne number if the results are going to be thrown away. Neither would I of course throw away the work already done.

You'll probably get a response from someone who knows better soon, but if it's been more than 60 days then your exponents get taken away and put back in the pool. Since Primenet likes to pretty much go in order of size, your exponents have probably been reassigned to someone else. (From the error message you got, at least one certainly has.)

If you want to do first time tests, I would close prime95/mprime, delete the worktodo.ini file, and any of the files named something like px123456, qx123455, or similarly but starting w/ any other letter and having different numbers, and then restart prime95/mprime.

If the exponents have been assigned to someone else, I don't think you will get credit for them unless you discover a prime as a double-check on an exponent that the person who now has the exponents made an error on.

If you had a first time exponent and turn it in after someone else gets it as a first time, you should get credit.

To put it more simply. If the exponent that you are working on is larger than 13 million, and you have completed more than 5-10% of work, finish it. Otherwise, just delete the files as mentioned above and contact the server again.

Thanks for your answers.

I'm testing M21419329, and it's at 41%. But I'm not so much after the credit, it indeed annoys me to do double unnecessary work. I think I'll remove the files and start with a new assignment.

Well, it is not unnecessary work since every number is double checked. So your test will be useful and save somone from performing another test later on.

maik · 2004-09-29, 16:28

Ok - in the meantime I already got a new assignment, but I save those files away and first go finish the previous one before continuing with the new M.

I should probably occasionally run the new one also just to keep up communication about it :-)

Thanks
Maik
