Version 1.0.17 should properly detect the availability of prefetch instructions on AMD machines with 3DNow! but without SSE. (Some earlier Athlons).
A more compact ABC file format will now be written by default. The old format will still be written if the --multisieve switch is given. Either format can be used for the input file:
Old format:
Code:
ABC $a*$b^$a$c // CW Sieved to: 100000000000 with gcwsieve
2000055 2 +1
2000110 2 +1
2000116 2 +1
2000128 2 +1
New format:
Code:
ABC $a*2^$a+1 // CW Sieved to: 100000000000 with gcwsieve
2000055
2000110
2000116
2000128
