Rover - we need you to contact us
 
You are the only user of LLRnet, and LLR has a problem. It doesn't matter if you are using the old LLRnet (and losing 10% of your machines) or the new substitute scripts with LLR 3.8.1. The wrong FFT size is being picked by the program. This results in 3% to 5% of the tests reporting a wrong residual. it could even result in missing a prime. The 3% to 5% is only a SWAG, but Lennart has accepted the challenge of determining a more precise number. If you could switch to PRPnet and PFGW 3.3.6 it would benefit you and the project. Please contact us, by replying to this post or via PM

Actually, if he's using the old LLRnet (i.e., LLR version 3.5.0) he's fine. The gwnum bug only affects LLR versions 3.8.0 and newer.

Note, of course, that LLR 3.5.0 is much, MUCH slower than the latest LLR or PFGW on base 5 numbers. For base 2 it's about 10% slower, but for other bases it's about 3 times slower. So it's still good to upgrade to PRPnet anyway. (Or, upgrade to the new LLRnet client after a fixed version of LLR is released that doesn't have the bug.)

Actually he is not. We still need him to contact us (Joe O or LTD).

LOL, I saw this thread under "New Posts" and didn't see what forum it was in.

I thought first it was a funny comment for the Mars Spirit Rover to contact us :)

LLRnet will be down sometime in the week of 13 December 2010. How long it will be down is not yet known. We will be updating the machine on which it runs, and LLRnet will have to be down while this happens.
