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.

}
This program: 1. Opens the file at `/tmp/file.txt` 2. Divides the file into 4 roughly equal chunks 3. Spawns 4 threads, each processing its chunk 4. Each thread: - Seeks to its starting position - Reads lines until it reaches its end position - Counts words in its chunk - Creates a JSON-formatted string of its counts 5. Prints each thread's JSON output on separate lines To compile and run: 
1
2
rustc wordcount.rs
./wordcount
The output will be 4 lines of JSON, one from each thread. Each JSON object will contain word counts for that thread's portion of the file. Note that words that span chunk boundaries might be counted incorrectly, and the same word might appear in multiple chunks. You'll need to merge the results externally. Example output might look like: 
1
2
3
4
{"word1": 5, "word2": 3}
{"word2": 2, "word3": 4}
{"word4": 1, "word2": 2}
{"word5": 3, "word1": 1}

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.

Docker Setup

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.

This program: 1. Takes no command line arguments and reads from `/tmp/file.txt` 2. Divides the file into 4 roughly equal parts by byte count 3. Spawns 4 threads, each processing its own part of the file 4. Each thread creates its own HashMap counting words in its section 5. Converts each HashMap to a JSON-formatted string 6. Prints each thread's results on separate lines To compile and run: 
1
2
rustc word_count.rs
./word_count
Note that this simple parallelization approach has some limitations: - Words that span chunk boundaries might be split - The chunks are divided by bytes, not lines or words - Each chunk starts counting from wherever it lands in the file However, it will give you 4 separate word count dictionaries that you can merge later. Each line of output will be a valid JSON dictionary representing the word counts for approximately 1/4 of the file. The output will look something like: 
1
2
3
4
{"word1": 5, "word2": 3, "word3": 1}
{"word2": 2, "word4": 4, "word5": 1}
{"word1": 3, "word6": 2, "word7": 1}
{"word3": 4, "word8": 2, "word9": 1}
You can then merge these dictionaries by combining the counts for matching words.

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.

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.

rustc word_count.rs
./word_count
This program: 1. Divides the file into 4 roughly equal chunks 2. Creates 4 threads, each processing its chunk 3. Each thread: - Seeks to its starting position - Reads lines until it reaches its end position - Counts word frequencies in its chunk - Converts the counts to JSON format 4. Prints one JSON object per line (4 lines total) Notes: - The program handles word boundaries between chunks by skipping the first line of chunks 1-3 (as they might start mid-word) - Each thread produces its own independent word count - The program uses only standard library features - The output will be 4 separate JSON objects, one per line - You'll need to merge the results yourself if you want a single combined count Keep in mind that this simple approach might miss some words at chunk boundaries, but it provides a reasonable parallel processing solution without requiring external crates.

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.

This program: 1. Opens the file at `/tmp/file.txt` 2. Divides the file into 4 roughly equal chunks 3. Spawns 4 threads, each processing its chunk 4. Each thread: - Seeks to its starting position - If not the first chunk, discards the partial word at the start - Reads its portion of the file - Counts words - Creates a JSON string of the counts 5. Prints each thread's JSON output on separate lines To compile and run: 
1
2
rustc wordcount.rs
./wordcount
The output will be 4 lines of JSON, one from each thread. Each JSON string will contain the word counts for that thread's portion of the file. Note that words that span chunk boundaries might be counted incorrectly, but this is a trade-off for parallel processing without more complex coordination between threads. For most text files, this should affect only a very small number of words (maximum 3 words, one at each boundary between chunks). The output format for each line will be like: 
1
2
3
4
{"word1": 5, "word2": 3, "word3": 1}
{"another": 2, "set": 4, "words": 1}
{"from": 3, "third": 2, "chunk": 1}
{"last": 4, "chunk": 2, "words": 3}
You can then merge these results as needed for the final counts.

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.

This program: 1. Splits the file into 4 roughly equal chunks based on file size 2. Creates 4 threads, each processing its own chunk 3. Each thread: - Seeks to its starting position - Reads lines until it reaches its end position - Counts words in its chunk - Creates a JSON-formatted string of its results 4. Prints each thread's results as a separate JSON object, one per line Some notes: - The program assumes the file exists at `/tmp/file.txt` - It uses basic file size division, which means it might split words across chunk boundaries - Each thread's output is a separate JSON object printed on its own line - It uses only standard library features, so it can be compiled directly with `rustc` - To compile: `rustc wordcount.rs` - To run: `./wordcount` The output will be 4 lines, each containing a JSON object with word counts for that chunk of the file. You'll need to merge these results yourself to get the total counts. Keep in mind that due to the simple chunking method, words that cross chunk boundaries might be counted incorrectly or split. For a more accurate count, you'd need a more sophisticated chunking method that respects word boundaries.
