PiBench Output Parser

A simple parser to parse the text output from pibench.

Why

Current PiBench does not support json/csv output yet; it prints the output to stdout and stderr.

We sometimes need to process hundreds of such text files, thus need a programmatic way to extract the useful information.

Plan

1. A shared library that can be called from Python. ✔️

2. A Webassembly version to support pibench-online. ✔️

3. Native rust version for pibench backend server. ✔️

Usage (Rust)

let data = PiBenchData::from_text(text);

Work with Javascript/NodeJS

npm install pibench-parser

import { PiBenchData } from "pibench-parser";
const text = "YOUR PIBENCH RESULT";
const result = PiBenchData.from_text(text).to_js_value();

Work with Python

import ctypes
from ctypes import c_char_p, c_void_p, CDLL

so_file = "/path/to/libpibench_parser.so"
functions = CDLL(so_file)

def text_to_json(text):
    json_str = functions.text_to_json(text.encode("utf-8"))
    try:
        return ctypes.cast(json_str, c_char_p).value.decode("utf-8")
    finally:
        functions.free_json_str(json_str)
