My machines are up and running.
Adjust-strategy 2 does use a bit more memory than the default, but each process should still fit within 4GB.

Done. I suppose it's possible he's already started working on it himself and just hasn't got round to updating the reservation page, so I'll keep everyone updated.
What parameters are you using...

I'm happy to leave this one to NFS@home unless there's more interest in a quick team-sieve.
We need a polynomial in any case, so I'm starting a CADO run with P=4M, admax=10M, incr=420. Help is...

Not sure if this counts as elegant:
Suppose n = ab where b>1 is odd. Then when we write n = a+...+a, one of the a's is in the middle, so we can easily rewrite this as a sum of consecutive...

Now on a c189.
I've run just under half a t50 so far, so if anyone wants to run ECM it would be best to start at the 55-digit level or higher.

And now a further 3500@40e7, 6700@65e7 and 3900@12e8.
In hindsight it might have been better for me to stick to 40/42e7 and for Yoyo to start at 85e7, but I expected Yoyo would have got going by...

Thanks - I hadn't properly taken on board that Yoyo is running more than a full t60.
I've done 1900@42e7 so far, as well as 300@40e7 on some memory-limited machines. Switching most machines to...
