Docker Setup

I have setup the docker container to run the model evaluation.

Initial Query

Write a self-contained Rust program that prints a JSON output of how often each word appears in a text file located in /tmp/file.txt. So if the file contains "This is is is, an example" then the program should print to stdout. {"This": 1, "is": 2, "is,": 1, "an": 1, "example": 1} Don't import any crates that would require a Cargo.toml file. I'll just compile it with `rustc yourfile.rs` and it should work. The program should be run by calling /path/to/rust_word_count with no arguments. Make it run in parallel on 4 cores at the same time, each job taking ~1/4 of the file. Print out 4 differnt json dicts, one per line. I'll do the merging. Do not import serde_json, write json output from scratch.

Output

Here's a simple Rust program that fulfills your requirements:

use std::fs::File;
use std::io::{Read, BufReader};
use std::path::Path;
use std::thread;
use std::collections::HashMap;

fn main() -> std::io::Result<()> {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path)?;
    let metadata = std::fs::metadata(file_path)?;
    let file_size = metadata.len();

    let chunk_size = file_size / 4;
    let mut handles = vec![];

    for i in 0..4 {
        let file = File::open(file_path)?;
        let start = i * chunk_size;
        let mut reader = BufReader::new(file);
        let mut buffer = vec![];

        // Read the chunk
        reader.seek(std::io::SeekFrom::Start(start))?;
        let mut bytes_read = 0;
        while bytes_read < chunk_size {
            let bytes = reader.fill_buf()?;
            let bytes_to_read = std::cmp::min(bytes.len(), chunk_size - bytes_read);
            buffer.extend_from_slice(&bytes[..bytes_to_read]);
            bytes_read += bytes_to_read;
            reader.consume(bytes_to_read);
            if bytes_to_read < bytes.len() {
                break;
            }
        }

        // Spawn a new thread to count words in the chunk
        let handle = thread::spawn(move || {
            let count = count_words(buffer);
            print_count(count);
        });

        handles.push(handle);
    }

    // Wait for all threads to finish
    for handle in handles {
        handle.join().unwrap();
    }

    Ok(())
}

fn count_words(buffer: Vec<u8>) -> HashMap<String, u32> {
    let string = String::from_utf8_lossy(&buffer);
    let words: Vec<&str> = string.split_whitespace().collect();
    let mut count = HashMap::new();

    for word in words {
        *count.entry(word.to_string()).or_insert(0) += 1;
    }

    count
}

fn print_count(count: HashMap<String, u32>) {
    print!("{");
    let mut first = true;
    for (key, value) in count {
        if first {
            first = false;
        } else {
            print!(", ");
        }
        print!("\"{}\": {}", key, value);
    }
    println!("}");
}

This program reads a file in chunks, spawns a new thread for each chunk, counts the words in each chunk, and prints the word counts as JSON dictionaries. Note that this program assumes that the file can be read into memory in chunks. If the file is too large to fit into memory, a different approach will be needed. Also note that the word counting is simple and does not handle punctuation properly. For example, "word" and "word," are considered different words.

Extract Code

I extracted the following code from that output:

use std::fs::File;
use std::io::{Read, BufReader};
use std::path::Path;
use std::thread;
use std::collections::HashMap;

fn main() -> std::io::Result<()> {
    let file_path = "/tmp/file.txt";
    let file = File::open(file_path)?;
    let metadata = std::fs::metadata(file_path)?;
    let file_size = metadata.len();

    let chunk_size = file_size / 4;
    let mut handles = vec![];

    for i in 0..4 {
        let file = File::open(file_path)?;
        let start = i * chunk_size;
        let mut reader = BufReader::new(file);
        let mut buffer = vec![];

        // Read the chunk
        reader.seek(std::io::SeekFrom::Start(start))?;
        let mut bytes_read = 0;
        while bytes_read < chunk_size {
            let bytes = reader.fill_buf()?;
            let bytes_to_read = std::cmp::min(bytes.len(), chunk_size - bytes_read);
            buffer.extend_from_slice(&bytes[..bytes_to_read]);
            bytes_read += bytes_to_read;
            reader.consume(bytes_to_read);
            if bytes_to_read < bytes.len() {
                break;
            }
        }

        // Spawn a new thread to count words in the chunk
        let handle = thread::spawn(move || {
            let count = count_words(buffer);
            print_count(count);
        });

        handles.push(handle);
    }

    // Wait for all threads to finish
    for handle in handles {
        handle.join().unwrap();
    }

    Ok(())
}

fn count_words(buffer: Vec<u8>) -> HashMap<String, u32> {
    let string = String::from_utf8_lossy(&buffer);
    let words: Vec<&str> = string.split_whitespace().collect();
    let mut count = HashMap::new();

    for word in words {
        *count.entry(word.to_string()).or_insert(0) += 1;
    }

    count
}

fn print_count(count: HashMap<String, u32>) {
    print!("{");
    let mut first = true;
    for (key, value) in count {
        if first {
            first = false;
        } else {
            print!(", ");
        }
        print!("\"{}\": {}", key, value);
    }
    println!("}");
}

Below is some student's code. I asked them to parallelize some code. Do not judge if it is correct, I have test cases for that. Logic errors are okay. So are synatx errors. Just tell me if they tried to parallelize it. use std::fs::File; use std::io::{Read, BufReader}; use std::path::Path; use std::thread; use std::collections::HashMap; fn main() -> std::io::Result<()> { let file_path = "/tmp/file.txt"; let file = File::open(file_path)?; let metadata = std::fs::metadata(file_path)?; let file_size = metadata.len(); let chunk_size = file_size / 4; let mut handles = vec![]; for i in 0..4 { let file = File::open(file_path)?; let start = i * chunk_size; let mut reader = BufReader::new(file); let mut buffer = vec![]; // Read the chunk reader.seek(std::io::SeekFrom::Start(start))?; let mut bytes_read = 0; while bytes_read < chunk_size { let bytes = reader.fill_buf()?; let bytes_to_read = std::cmp::min(bytes.len(), chunk_size - bytes_read); buffer.extend_from_slice(&bytes[..bytes_to_read]); bytes_read += bytes_to_read; reader.consume(bytes_to_read); if bytes_to_read < bytes.len() { break; } } // Spawn a new thread to count words in the chunk let handle = thread::spawn(move || { let count = count_words(buffer); print_count(count); }); handles.push(handle); } // Wait for all threads to finish for handle in handles { handle.join().unwrap(); } Ok(()) } fn count_words(buffer: Vec<u8>) -> HashMap<String, u32> { let string = String::from_utf8_lossy(&buffer); let words: Vec<&str> = string.split_whitespace().collect(); let mut count = HashMap::new(); for word in words { *count.entry(word.to_string()).or_insert(0) += 1; } count } fn print_count(count: HashMap<String, u32>) { print!("{"); let mut first = true; for (key, value) in count { if first { first = false; } else { print!(", "); } print!("\"{}\": {}", key, value); } println!("}"); } Answer either 'The student passes' or 'The student fails'.
