PROGRAM:
NAME
pyecm - Number factorization with the Elliptic Curve Method
SYNOPSIS
pyecm [OPTIONS] [FACTORS]...
DESCRIPTION
pyecm factors numbers using the Elliptic Curve Method (ECM). If FACTORS is given, it will
factor each one of these. Otherwise, it will factor from standard input. You can type
"exit" to quit pyecm at any time.
-h, --help
Get help using pyecm.
--portion=num
Does only part of the work for factoring, corresponding to what fraction of the
total work the machine is doing. Useful for working in parallel. For example, if
there are three machines: 1GHz, 1GHz, and 2GHz, print should be set to 0.25 for the
1GHz machines and 0.5 for the 2GHz machine. Implies -r and -v. -r is needed to
avoid duplicating work and -v is needed to report results.
--ov=num
Sets the value of the internal parameter ov, which determines the trade-off between
memory and time usage. Do not touch if you do not know what you are doing. Please
read all the documentation and understand the full implications of the parameter
before using this switch.
-n, --noverbose
Terse. On by default. Needed to cancel the -v from the --portion or --random
switches. If both -n and -v are specified, the one specified last takes precedence.
-r, --random
Chooses random values for sigma, an internal parameter in the calculation. Implies
-v; if you're doing something random, you want to know what's happening.
-v, --verbose
Explains what is being done with intermediate calculations and results.
EXAMPLES
pyecm 2^3-1 1000 "(3^13+2)*5"
Factor 7, 1000, then 7971625.
pyecm Get factors from standard input.
