puzzle #120

in.txt
Code:
800000000000000000000000000000
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
02CEB6CBBCDBDF5EF7150682150F4CE2C6F4807B349827DCDBDD1F2EFA885A2630

where in c++ code read and use value 800000000000000000000000000000 and FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF to use as range search

I would like to compare c++ work
and use modify old python code to use range like c++

now I use JeanLucPons Kangaroo by split keyspace to small part and search
when use full rank, my CPU very high and use Full memory, I think 16GB laptop not enough for 120bit search may be need 64Gb to 128GB high end memory board
This is just not true. The RAM consumed/used is not dependent on the bits being search...it comes down to your DP setting and how often you save the work file.  I don't see your settings/flags when starting the program but you are using a very low -d setting or that plus using a long save to file time.
