Operation: Billion Digits - Page 23

I mean, how do I stop the current test (preferably without loss of information)?

Also, the second column ("Digits") means the bit depth that the exponent has already been factored to, right?

To work with a MAC you'll have to download the MAC version of Factor3_1 (version 3.2 is not yet available, the link will be updated automatically when compiled) here.

No Cygwin libraries should be needed AFAIK.

1 - Yes, Ctrl-C works fine. You can restart the search with "factor3_2 -r"
2 - Yes.

What's factor3_2 -r?

factor3_2 is the name of the program to invoke.

"-r" is the resume switch: it permits to resume from a previously saved file without loosing data.

Its not working. When I run factor 3_2, it first asks:

"Please enter the exponent to be factored: 2^"

When I type in "-r", it just closes the window.

Sorry, maybe my English is not clear

IF
you are starting a new exponent
THEN
you must enter "./factor3_2" and provide exponent, start bit and stop bit
ELSE IF
you have stopped a range still to be completed (Ctrl-C or power-off)
THEN
you can restart it from saved data typing "./factor3_2 -r" from the command line.

-r is an argument you may or may not provide on the command line to resume your previous work.

I'll do that from 66 to 67 bits.

I finally got it to work. Sigh, Command-line interfaces are so difficult to work with...

Anyway, is it possible to have two saved files simultaneously (i.e. does starting a new exponent make it impossible to resume the old exponent?)

Consider starting two instances from two different directories...

I'm not (yet) planning the management of a .INI file to configure the savefile name. Maybe in Version 4.0

BTW, did you choose an exponent for Billion or 100Million projects?
