[QUOTE=10metreh;153744]And you missed out a C72 and a couple of C74s.[/QUOTE]

Oh yes, I certainly didn't finish. And the earlier work I did only found one factor per number, so my work from last week was mainly splitting some of the remaining numbers with msieve and/or some ECM program (mostly gmp-ecm).

The combined time for a C72 and two C74s is only about 20 minutes even on my slow computer. Why didn't you do them?

As these are SNFS numbers, I would ECM to lower limits (25 digits rather than 30).

ATM I'm doing a C97 from my aliquot sequence, so I won't do the C8x's straight away.

Because my time was the scarce resource, not computing power.

Thank you for your comments!

Looks like there is a lot of work to do. First I'll rewrite the parser, the current one is not 100% clean code, hard to debug, this may take a few days.

Here we go :smile:

Things that should work now:
Fibonacci sequence
fib(x)
fibonacci(x)
or short Ix

Lucas numbers
lucas(x)
Lx

product of the first N primes
x##

The bugs R. Gerbicz mentioned
(and a few more)


I'd be happy if you give it a try

So I just tried submitting a factor and now it provides some feedback which is great. I'm getting the message:

[B]Waiting for worker ... (unknown)[/B]

The page refreshes itself fairly often but the message has stayed that way for maybe 15-20 minutes now. Does that mean it has been queued up and at some point one one of the worker machines becomes available it will be processed? Or did something go wrong and the (unknown) means it did not get scheduled anywhere so will never get processed?

Just forgot to start the workers again ..

Ok so now when I enter a factor, no message shows up, and the factor does not show up in the list of factors either.

I got a similar problem earlier. When I submitted a factor that finished the number, the submitted factors appeared in the form "Factor submitted: XXX" and in the factorization but the number was still "Composite, factors known" rather than "Composite, fully factored". If I searched for that number again the problem would be sorted.

i wouldnt be surprised if what you are seeing is something to do with waiting for the final cofactor to have its primality checked

[QUOTE=Syd;153590]I imported some factor tables using the workers. First the mersenne.org's "factors.cmp", now I'm doing the cunningham tables. Which one should be next?[/QUOTE]
