How far along are you in your 100M digit LL test?

How far along are you in your 100M digit LL test? What is your expected finish date?

I got caught with an exponent that hadn't gotten a P-1 test or factoring through 2^75 (which may actually be the norm), so I'm 0% of the way through. I'm probably looking at another month to six weeks before my LL test even starts. The only thing I have is an approximate length of time which will bring me to February 2014.

What if there are some calculation errors during all this time? You'll have to restart the whole calculation, right?

If staging files are kept at periodic intervals then it might be possible to avoid beginning from the start. But a much better solution is to only do computations that take a long time (> 1 month IMO) on a machine with ECC.

The only completed 100M digit test has errors, and it's not going to be double checked for a long time.

Another good question would be - how would one know that there were no calculation errors during all this time? ("Because Prime95 didn't report any errors" is not the right answer!)

2 checksums that match would establish that there were no errors.
