Good luck.

I had three system crashes so far from HDMI not playing fair with the gpu and monitor but mpi-ecpp's restart facility works perfectly. Now reached as far as

Code:

-- Size [96]: 28063 bits
   Time for discriminant -44037848: 1835.8 (372.4)
   largest prime of d: 409
   largest prime of h: 11
       discriminants: 46.8 (47.5)

Sorry, I didn't notice this thread! I'll do (3594,697).

Yeah, it is confusing. I suggest that we try to stick to this thread. I have been as promiscuous as anyone

Mine has now reacched stage 150, 24945 bits still to go.

Done in 5.7 hours. Phase 2 took the time for the largest step, 1.4 hours. Now working on 3155_1966.

Done. Now running 3201_1772, 3225_1678, and 3392_1209.

It's impressive!

Code:

--- Time for second ECPP step: 210632.6 (7131.1)
--- Total time for ECPP:       1426849.4 (49834.4)

(Time in brackets is real time.)
I would like to take a bunch now:

L(3100, 2447)
L(3160, 2119)
L(3268, 1755)
L(3470, 1173)
L(4309, 298)
L(3217, 2118)

I'll take (7035,34) next.

Looking forward to seeing these resolved in factordb. Is anyone doing L(3522,851) or L(3896,579)? Next ones up are:

L(3502,1271)
L(3121,3070)
L(3996,539)
L(3369,1766)
L(5488,99)
L(3509,1330)
L(3142,3089)
L(3188,2781)
L(3543,1262)

I will take 3522,851 if noone else wants it.

Seems only fair because it was I who found it PRP.

Started it running with 7 slots on a 6 core hyperthreaded system. It is taking much less memory so far than the earlier run --- 0.65G as opposed to 1.6G per process.
