Mersenne prime testing done quickly!
libpthread
Run stemprime $number to test whether 2^$number-1 is prime.
Run stemprime --help to view usage and help info
Run stemprime N0 N1 N2 N3 ... to test a series of exponents, in parallel (i.e. stemprime 31 67 127 128 would test 2^31-1, 2^67-1, 2^127-1, and 2^128-1).
| Option | Takes | Function |
|---|---|---|
--info |
N/A | Prints version and name info about the program |
-h, --help |
N/A | Prints help and usage information |
--authors |
N/A | Prints authors name and email addresses |
-v=2 |
number | Sets verbosity level (3 prints all, 0 is only neccesary info) |
-d=./ |
string | Where to store and restore from progress files |
-nc, --no-checkpoint |
N/A | If enabled, no checkpoint files are used |
-t, --time-interval=10000 |
number | Prints each t iterations |
|
number | The exponent to perform LL test on M n |
Run ./configure && make && make install
Run stemprime --help to view the help info.
An example usage would be like: stemprime 31 to test 2^31-1
You will need autotools, GMP, , and pthreads.
Then, run autoconf -i.
And, finally, install like any other.
i.e. ./configure && make
The binary is ./src/stemprime
| Option | Description | Note |
|---|---|---|
--enable-static |
Builds a static executable (for distributing) | Doesn't always work on macOS |
--with-X=XDIR |
Gives info for finding library X in XDIR |
See the next section |
If you have installed GMP, cargs, or pthreads in a non standard location, you can modify the configure step like so:
./configure --with-gmp=GMPDIR --with-cargs=CARGSDIR ...
GMPDIR should be what you set --prefix while configuring GMP, CARGSDIR should be what you set --prefix to while configuring cargs, etc.
Then, run make like the examples give, and you should be good!
