download the llrtools.

-insert in 'times.txt' the timings of your CPU for a given FFTlen

for my Quad 2.4GHz i do this for the range 21-25:

Code:

6144 0.096
7168 0.116
8192 0.120
10240 0.168
12288 0.207
14336 0.250

- call 'get_time.exe' with the parameter of the LLR-input file

and the output is like mine:

Code:

--- Quad Q6600 2.4GHz ---
number of (k,n) pairs in file: 19448
estimated total time for LLR testing the whole file: 656024.274 sec
average time per LLR test: 33.732 sec

so these 656000 secs -> ~182 hours -> 7.6 days (so about 1/4 for my quad)!

the other 2 progs in there:

- fft_len gives you all the FFTlen for a given k and n-range

- av_time gives you the average time per LLRtest for a given k and n-range

try it! it's easy to use with many information you get.
