71.0-72.0M to 64 bits
 

I'll take this range. 24032 exponents.

Submitted via the PrimeNet Server v5.0:
71.4-71.5M 2410 exponents with 52 (2.16%) factors found
71.7-71.8M 2373 exponents with 39 (1.64%) factors found

Other subranges in progress (about 60% of the whole range done).

Progress
 

Due to some problems with comps I had to redistribute (sub)ranges. Some of them (subranges, no comps) had been completed, so I submitted them manually (PrimeNet server v5). As for today the range is completed in more than 90% and should be ready in a week (at most 10 days with slower CPU's).

Done
 

done and submitted via PrimeNet Server v5. 343 (1.43%) factored out.
