# mtsum
A parallel checksum utility using a Merkle tree, designed for huge files.


## Motivation
With the latest PCIe 4.0 and 5.0 SSDs, a single processor thread is insufficient to fully utilize their bandwidth.
This utility leverages multiple threads to compute a file’s checksum in parallel using a Merkle tree structure, 
enabling efficient checksum calculations for large files in a reasonable time.


## Usage
`Usage: mtsum [--help] [--version] [-p processors] [-a algorithm] path`
```
Positional arguments:
  path           path to input file [required]

Optional arguments:
  -h, --help     shows help message and exits
  -v, --version  prints version information and exits
  -p             number of processors to use [nargs=0..1] [default: 8]
