This program calculates how much time your CPU takes to compute n digits of PI using Chudnovsky Algorithm and n prime numbers and uses the GNU Multiple Precision Arithmetic Library for most of the computations.
To compile in a linux environment (Ubuntu or Raspbian) install the necessary libraries doing:
sudo apt-get install libgmp3-dev
sudo apt-get install libssl-dev
Then compile doing:
gcc -O3 -Wall -o cpubench cpubench.c -lgmp -lssl -lcrypto -fopenmp
You can now run your own benchmark with sudo ./cpubench <number> <options>. An example of this is sudo ./cpubench 5000 --singlethreaded --nodigits.
To see further instructions you can do just sudo ./cpubench and all the options will be displayed.
