2,1778L
Sorry to be off topic, but,
I am just setting up the parameters for 2,1778L with difficulty 230 when I encountered up this job of similar difficulty levels! 230*0.7 = 161. 230 SNFS difficulty = 161 GNFS difficulty. Here is my polynomial file for 2,1778L that I just now set up: Code:
n: 187456795062290175781588001552911615336516481836838901307910624762737156478204777835354105902206650861355396494419638960993048427307433062550898806001787475198429902286327892727708624452163107713035095622371850541 Y1: 9223372036854775808 Y0: 170141183460469231731687303715884105729 c6: 1 c5: 2 c4: 10 c3: 20 c2: 16 c1: 32 c0: 8 skew: 2.828427125 type: snfs rlim: 60000000 alim: 60000000 lpbr: 29 lpba: 29 mfbr: 58 mfba: 58 rlambda: 2.6 alambda: 2.6 1) I used up rlim = alim = 60M, but you use rlim = alim = 50M. 2) I am thinking up of starting to sieve up from q = 20M, but bsquared has started up from q = 10M onwards. 3) You sieve up the algebraic side only? I think of sieving up the rational side as well. 4) You are using up the lattice siever 4I14e, but I use up 4I15e, is it OK? 5) Finally, notice that I use up only 29 bit large primes, but you use up 30 bit large primes. 29 bit large primes will make up the filtering and then the linear algebra stages much easier, right? Considering that things, which is optimal? Last fiddled with by Raman on 20091205 at 08:36

It is a very nice race!
Let's see up who finishes off the factoring of number with the same difficulty at first. I have run up 2,1778L on upto 17 dual core systems today. But, apologize about me up that I cannot contribute up to this project at all. I cannot send up several GB of data of relations by using the FTP server connections at all.
