Default The latest version.


The latest version of has the folowing enhancements. In order of significance:

If the degree is not optimal adjust all parms according to how far from the crossover we are. This significantly speeds up quartics at around 190 digits.

MINRELS chosen according to (but not tested in all ranges).

On Linux helper systems the first thread to notice the cols file exists kills all the other thread's so less time wasted sieving once we have enough relations.

Write a log message for error conditions such as the input number being probably prime. Useful when doing a series of runs unattended.

Cleanup should now remove all the large work files (.dat etc).

Speed up locking for polynomial selection.

Optional preliminary ECM testing. Only useful if you have no idea how much ECM testing the input numbers have had.
