Primecoin: Update windows product version and copyright notice
2013-07-25 20:59:39 +03:00
bd96b81cb0
Added a new configurable round primorial adjustment system.
...
The new parameter -gensieveroundpercentage (defaults to 30) determines how much time should be spent generating the sieve.
The round primorial is then adjusted so that the desired amount of time is spent generating the sieve.

Change version to -hp8.
2013-07-25 18:04:14 +03:00
0fa0615efb
Fix performance regression on mainnet caused by round primorial being adjusted too low.
...
The expected time dropped when 0 primes were found which caused the adjustment system to always decrease the round primorial.
Changed the calculation so that expected time is very high with 0 primes found.
Added an additional check so that round primorial is always incremented when 0 primes are found.

Only use the fast-div test for the first number in the chain because it skips fractional length calculation, thus preventing a potential block! Thanks to mtrlt for spotting this.
