Dataset Generator

This folder holds the generator code written to create a dataset to test our implementation.

Files

1. generate.cpp: generates a dataset depending on the opts data structure.

Description

The opts data structure is as follows:

    struct opts {
        int n_files_start;
        int n_files_end;
        int step;
        int m_batches;
        string path;

        int minlength;
        int maxlength;
    };

1. n_files_start: Number of files to start with. The generator would generate n_files_start number of files in the first iteration.
2. n_files_end: Number of files to end with. The last iteration would generate n_files_end number of files.
3. step: The step jump to be taken at every iteration. If the first iteration generated x then the next generation would generate x + stepfiles.
4. m_batches: The number of batches per step. This is done to calculate the average speed per step. Every batch contains the current n number of files.
5. path: The output directory.
6. minlength: minimum size of generated file.
7. maxlength: maximum size of generated file.

Instructions

1. Modify the opts vars object in main to your needs.
2. g++ generate.cpp
3. ./a.out

Potential improvement

Make it accept nice parsed commandline arguments.
