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 reads a text file from `/tmp/file.txt`, splits it into 4 parts, and runs 4 threads in parallel to count the word occurrences for each part. It prints out 4 separate JSON dictionaries, one per line. You'll need to merge these dictionaries to get the final result. To compile and run the program, save it to a file named `rust_word_count.rs` and execute: 
1
2
$ rustc rust_word_count.rs
$ ./rust_word_count
Please note that this program assumes the file's size is a multiple of 4. If the file's size is not a multiple of 4, some threads may process more lines than others. Additionally, the JSON output format does not include commas after the last key-value pair in each dictionary, so you may need to handle that when merging the dictionaries.

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.

This program uses four threads to process the file in parallel, with each thread handling approximately one-fourth of the file. It writes the JSON output to `stdout`, with each dictionary on a separate line. Note that this program uses the synchronous version of the `tokio` runtime, so you can compile it with `rustc` without the need for a `Cargo.toml` file. Please note that this program does not sort the output, and the words might not appear in the same order across the different dictionaries. If you need the words to be sorted, you would need to merge the dictionaries and sort them after all threads have completed their work. Also, keep in mind that this program does not handle errors robustly, and may panic if the provided file does not exist or is not readable. You may want to add error handling to make it more robust in a real-world application.

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 uses the standard library's `fs` and `io` modules to open and read the file, and the `thread` module to create and manage the threads. It also uses the `sync` module to share data between the threads. The program reads the file line by line, and skips and takes the appropriate number of lines for each thread based on the total number of lines in the file. Each thread maintains its own local word count, and then appends it to the shared word count after it is finished processing its lines. The shared word count is protected by a mutex to ensure that it can only be accessed by one thread at a time. After all the threads have finished processing their lines, the program sorts the shared word count by word, and then formats it as a JSON string using the `format!` macro. Note that this program does not handle edge cases such as empty files, or files that cannot be opened, and it does not validate that the input file is a valid text file. It also does not handle cases where the number of lines in the file is not evenly divisible by the number of threads. Also note that this program does not include error handling, and it panics if any errors occur. In a production environment, it would be better to handle errors gracefully, and return an error code or error message to the user. Finally, this program does not handle the merging of the json output, it is just printing 4 different json dicts, one per line. I hope this helps! Let me know if you have any questions or if you would like further assistance.

Final Answer: False

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 reads the text file `/tmp/file.txt`, splits it into 4 chunks, and processes each chunk in parallel using 4 threads. The word counts are stored in an `Arc<Mutex<Vec<(String, u32)>>>` data structure, which allows for safe concurrent access from multiple threads. After processing all the chunks, the program prints out 4 JSON dictionaries, one per line. Note that the word counts may not be in the same order as in the input file, as the threads process different chunks independently. To compile and run the program, save it as `rust_word_count.rs` and run the following commands: 
1
2
$ rustc --edition 2021 rust_word_count.rs
$ ./rust_word_count
Make sure you have a file named `/tmp/file.txt` with the required text content. Replace the contents of `/tmp/file.txt` with "This is is is, an example" for testing purposes. Keep in mind that the program does not merge the JSON dictionaries. You'll have to do that manually or write additional code to merge them if needed. Also, note that the program uses the 2021 edition of Rust, so make sure you have a recent version of Rust installed.

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 uses the Rayon library for parallel processing, which is included in the standard library. It reads the `/tmp/file.txt` file and processes it in parallel using 4 threads. Each thread generates a JSON dictionary containing word counts for its part of the file. The main function then prints each dictionary to the standard output. Keep in mind that this solution may not produce the exact output you provided in the question, as it splits the text into words based on whitespace and does not consider punctuation separately. If you want to handle punctuation more accurately, you may need to use a more sophisticated tokenization approach. To compile and run the program: 
1
2
$ rustc word_count.rs
$ ./word_count
Make sure you have a valid file at `/tmp/file.txt` with the example text provided in the question. The program will print 4 JSON dictionaries, one per line, containing the word counts for each portion of the file.

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.
