You're missing the point entirely- you have copied / used parameters from either RSA768 (a 232-digit number) or RSA-240. These are, you know, SIXTY or more digits smaller than the number you wish...

The MurphyE score depends on other parameters that you didn't list. You also didn't list the polynomial, so I can't evaluate its quality myself.

You didn't list the large-prime bound parameters,...

The poly score matches the record polys for GNFS199 or GNFS200. I agree this is a nice warmup for a team-CADO-sieve. Param selection depends on whether we go for I=16 and something like 8-12GB per...

What SNFS difficulty is it? What poly score (this most directly translates to GNFS difficulty)?
CADO is not really intended for SNFS jobs, and I don't have any experience with SNFS parameter...

I think this particular candidate falls into a no-man's-land, where the lack of possible record factorization acts against a possible XSEDE proposal yet it's too big for any single machine we have...

Greg has in the past expressed disinterest in projects using LP>33 because of runaway storage needs. Indeed, even if we give up 10+% efficiency to drop LP to something like 35/37 we'll still need on...

In case anyone is silly enough to try some polyselect, here is what I ran in CADO for my small search:
tasks.polyselect.degree = 6
tasks.polyselect.P = 40000000
tasks.polyselect.admax = 1e5...

RSA768 was factored with the equivalent of I=16 on CADO (same sieve region as NFS@home's 16fV5 siever). I=17 may be faster, but has a memory footprint too large for most users (I failed to get a...

Thank you!
It should be noted that axn posted the poly for RSA-768; its score is 30% better after 20 core-years of search (~eleven years ago) than my RSA-232 after 2 core-weeks.

Poly select and test-sieving for RSA232

The path for mere mortals to contribute to a factorization of RSA-896 or RSA-1024 may include getting an empirical sense for how our current tools scale for projects of 230+ digits.
As a start on...
