Usage

Prime number generator

$ sieve -n 42
2 3 5 7 11 13 17 19 23 29 31 37 41

$ sieve -h
usage: sieve [-h] [-n LIMIT]

The Sieve of Eratosthenes.

Returns the list of prime numbers up to a maximum integer.

optional arguments:
  -h, --help            show this help message and exit
  -n LIMIT, --limit LIMIT
                        maximum integer up to which the prime numbers are searched. (default 100)

Prime-counting function

$ prime-counting -n 42
13

$ prime-counting -h
usage: prime-counting [-h] [-n LIMIT]

Prime-counting function

Counts the number of prime numbers less than or equal to an integer number.

optional arguments:
  -h, --help            show this help message and exit
  -n LIMIT, --limit LIMIT
                        maximum integer up to which the prime numbers are counted. (default 100)

CI/CD

This project uses GitLab CI/CD for continuous integration and deployment. The pipeline is defined in the .gitlab-ci.yml file located in the root directory of the repository.

For more information on how CI/CD is implemented at CINECA, please refer to the documentation: https://docs.hpc.cineca.it/general/access.html#continuous-integration-ci-cd-at-cineca
