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.

This program does the following: 1. It opens the file at `/tmp/file.txt`. 2. It divides the file into 4 chunks based on file size. 3. It spawns 4 threads, each processing approximately 1/4 of the file. 4. Each thread counts word occurrences in its chunk and formats the result as JSON. 5. The main thread prints the JSON output from each worker thread. The program uses only standard library features and can be compiled with `rustc`. It doesn't require any external crates or a Cargo.toml file. To run the program, compile it with: 
1
rustc yourfile.rs
Then run the resulting executable: 
1
./yourfile
This will process the file at `/tmp/file.txt` and print four JSON objects, one per line, representing the word counts from each chunk of the file. Note that this approach may split words that happen to be at the chunk boundaries, so the results might not be exactly the same as processing the entire file sequentially. For a more accurate result, you'd need to implement logic to handle words that cross chunk boundaries, which would add significant complexity to the program.

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::collections::HashMap; use std::fs::File; use std::io::{BufRead, BufReader, Seek, SeekFrom}; use std::sync::{Arc, Mutex}; use std::thread; fn main() { let file = File::open("/tmp/file.txt").expect("Failed to open file"); let file_size = file.metadata().expect("Failed to get metadata").len(); let chunk_size = file_size / 4; let file = Arc::new(Mutex::new(file)); let mut handles = vec![]; for i in 0..4 { let file = Arc::clone(&file); let handle = thread::spawn(move || { let mut file = file.lock().unwrap(); file.seek(SeekFrom::Start(i * chunk_size)).unwrap(); let reader = BufReader::new(file); let mut word_count = HashMap::new(); for line in reader.lines().take_while(|_| file.stream_position().unwrap() < (i + 1) * chunk_size) { let line = line.unwrap(); for word in line.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } } format_json(&word_count) }); handles.push(handle); } for handle in handles { println!("{}", handle.join().unwrap()); } } fn format_json(word_count: &HashMap<String, i32>) -> String { let mut json = String::from("{"); for (i, (word, count)) in word_count.iter().enumerate() { if i > 0 { json.push_str(", "); } json.push_str(&format!("\"{}\": {}", escape_json(word), count)); } json.push_str("}"); json } fn escape_json(s: &str) -> String { s.replace('\\', "\\\\") .replace('"', "\\\"") .replace('\n', "\\n") .replace('\r', "\\r") .replace('\t', "\\t") } Answer either 'The student passes' or 'The student fails'.

This program does the following: 1. It opens the file at `/tmp/file.txt`. 2. It calculates the file size and divides it into 4 equal chunks. 3. It spawns 4 threads, each processing approximately 1/4 of the file. 4. Each thread counts the words in its chunk and stores the counts in a `HashMap`. 5. After processing, each thread formats its `HashMap` into a JSON string. 6. The main thread prints the JSON string from each worker thread, one per line. The `format_json` function manually creates a JSON string from the `HashMap`, and the `escape_json` function handles escaping special characters in the JSON string. To compile and run this program: 1. Save it to a file, e.g., `word_count.rs` 2. Compile it with: `rustc word_count.rs` 3. Run it with: `./word_count` This will print 4 JSON strings, one per line, each representing the word count for approximately 1/4 of the file. You'll need to merge these results yourself to get the final word count for the entire file. Note that this simple approach may split words across chunk boundaries, potentially leading to slight inaccuracies in the word count. For a more accurate count, you might need to implement a more sophisticated chunking strategy.

Query

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::collections::HashMap; use std::fs::File; use std::io::{BufRead, BufReader, Seek, SeekFrom}; use std::sync::{Arc, Mutex}; use std::thread; fn main() { let file = Arc::new(Mutex::new(File::open("/tmp/file.txt").unwrap())); let file_size = file.lock().unwrap().metadata().unwrap().len(); let chunk_size = file_size / 4; let mut handles = vec![]; for i in 0..4 { let file = Arc::clone(&file); let handle = thread::spawn(move || { let mut word_count = HashMap::new(); let mut file = file.lock().unwrap(); file.seek(SeekFrom::Start(i * chunk_size)).unwrap(); let reader = BufReader::new(file); for line in reader.lines() { if let Ok(line) = line { for word in line.split_whitespace() { *word_count.entry(word.to_string()).or_insert(0) += 1; } } if reader.stream_position().unwrap() >= (i + 1) * chunk_size { break; } } format_json(&word_count) }); handles.push(handle); } for handle in handles { println!("{}", handle.join().unwrap()); } } fn format_json(map: &HashMap<String, i32>) -> String { let mut json = String::from("{"); for (i, (key, value)) in map.iter().enumerate() { if i > 0 { json.push_str(", "); } json.push_str(&format!("\"{}\": {}", escape_json(key), value)); } json.push('}'); json } fn escape_json(s: &str) -> String { s.replace('\\', "\\\\") .replace('"', "\\\"") .replace('\n', "\\n") .replace('\r', "\\r") .replace('\t', "\\t") } Answer either 'The student passes' or 'The student fails'.

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.

This program does the following: 1. It opens the file at `/tmp/file.txt`. 2. It divides the file into 4 chunks based on byte size. 3. It spawns 4 threads, each processing one chunk of the file. 4. Each thread counts the words in its chunk and returns a `HashMap` of word counts. 5. The main thread collects the results from all threads and prints them as JSON. To compile and run this program: 1. Save it to a file, e.g., `word_count.rs` 2. Compile it with `rustc word_count.rs` 3. Run the resulting executable with `./word_count` The program will output 4 JSON objects, one per line, each representing the word counts from one quarter of the file. Note that this approach may split words that happen to be at the boundaries of chunks. For a more accurate count, you might need to implement a more sophisticated chunking strategy or merge the results afterwards.

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.

This program does the following: 1. It opens the file at `/tmp/file.txt`. 2. It calculates the file size and divides it into 4 chunks. 3. It spawns 4 threads, each processing approximately 1/4 of the file. 4. Each thread counts the words in its chunk and stores the counts in a `HashMap`. 5. The `format_json` function converts the `HashMap` to a JSON string without using any external crates. 6. Each thread returns its JSON string, which is then printed to stdout. To compile and run this program: 1. Save the code to a file, e.g., `word_count.rs`. 2. Compile it with `rustc word_count.rs`. 3. Run the compiled program with `./word_count`. The program will output 4 JSON strings, one per line, each representing the word counts for a quarter of the file. You'll need to merge these results yourself to get the final word count for the entire file. Note that this approach may have some inaccuracies at the chunk boundaries, as words might be split between chunks. For a more accurate count, you'd need to implement a more sophisticated chunking method or post-process the results to handle split words.

This program does the following: 1. It opens the file at "/tmp/file.txt". 2. It calculates the file size and divides it into 4 equal chunks. 3. It spawns 4 threads, each processing approximately 1/4 of the file. 4. Each thread counts word occurrences in its chunk and formats the result as a JSON string. 5. The main thread collects and prints the JSON results from all 4 threads. Key points: - The program uses only standard library features, so it can be compiled with `rustc` without a Cargo.toml file. - It runs in parallel on 4 cores, each processing about 1/4 of the file. - It prints 4 different JSON dictionaries, one per line. - The JSON output is formatted from scratch without using serde_json. - The program handles JSON string escaping for special characters. To compile and run:

2
rustc yourfile.rs
./yourfile
This will process the file at "/tmp/file.txt" and print the word count results as JSON, one dictionary per line, for each of the 4 parallel jobs.

Query

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::collections::HashMap; use std::fs::File; use std::io::{BufRead, BufReader, Seek, SeekFrom}; use std::sync::{Arc, Mutex}; use std::thread; fn main() { let file = Arc::new(Mutex::new(File::open("/tmp/file.txt").expect("Failed to open file"))); let file_size = file.lock().unwrap().metadata().unwrap().len(); let chunk_size = file_size / 4; let mut handles = vec![]; for i in 0..4 { let file = Arc::clone(&file); let handle = thread::spawn(move || { let mut word_counts = HashMap::new(); let mut file = file.lock().unwrap(); file.seek(SeekFrom::Start(i * chunk_size)).unwrap(); let reader = BufReader::new(file); for line in reader.lines().take_while(|_| file.stream_position().unwrap() < (i + 1) * chunk_size) { let line = line.unwrap(); for word in line.split_whitespace() { *word_counts.entry(word.to_string()).or_insert(0) += 1; } } format_json(&word_counts) }); handles.push(handle); } for handle in handles { println!("{}", handle.join().unwrap()); } } fn format_json(map: &HashMap<String, i32>) -> String { let mut json = String::from("{"); for (i, (key, value)) in map.iter().enumerate() { if i > 0 { json.push_str(", "); } json.push_str(&format!("\"{}\": {}", escape_json(key), value)); } json.push('}'); json } fn escape_json(s: &str) -> String { s.replace('\\', "\\\\") .replace('"', "\\\"") .replace('\n', "\\n") .replace('\r', "\\r") .replace('\t', "\\t") } Answer either 'The student passes' or 'The student fails'.
