[QUOTE=fivemack;136581]Factor base bounds are min(8e7, Qrat) on the rational side, min(10e7, Qalg) on the algebraic side. Sieve region is 2^15 * 2^14.



Ah, I say '10^6 Q' to mean 'Q between N and N+10^6', which corresponds to about 55,000 usable Q values. In the 220 hours, that means about 14.4 seconds per ideal.[/QUOTE]

Thanks. How much real memory did the siever require for these
parameters?

It uses about 560MB of virtual memory, 240M real memory.
