By leveraging HPX's advanced parallel algorithms and execution policies, this addon allows developers to perform CPU-intensive operations efficiently without blocking the Node.js event loop.\n\n**Key Benefits:**\n- **Seamless Parallelization:** Offload heavy computations to HPX threads while maintaining a responsive Node.js application.\n- **Advanced Execution Policies:** Utilize HPX's parallel, sequential, and unsequenced execution policies to optimize performance based on your specific use case.\n- **Customizable Predicates \u0026 Comparators:** Define and use custom JavaScript functions for complex data processing tasks.\n- **Batch Processing:** Enhance performance by minimizing cross-boundary calls between C++ and JavaScript through batch processing strategies.\n\nFor a comprehensive understanding of the addon's architecture and advanced usage scenarios, refer to the [Architecture](./docs/Architecture.md) and [Internals](./docs/Internals.md) documents. For additional examples and practical demonstrations, explore the [Examples](./docs/Examples.md) section.\n\n---\n\n## Features \u0026 Capabilities\n\n- **Seamless Parallelization of C++ Algorithms in Node.js:**  \n  Offload heavy computations to HPX and retrieve results as typed arrays, ensuring non-blocking operations in your Node.js applications.\n\n- **Configurable Execution Policies:**  \n  Choose between sequential (`seq`), parallel (`par`), or parallel unsequenced (`par_unseq`) execution policies. Control the transition from parallel to sequential execution based on a user-defined threshold.\n\n- **Custom Predicates and Comparators:**  \n  Define custom JavaScript predicate or comparator functions. The addon employs [ThreadSafeFunctions (TSFNs)](https://github.com/nodejs/node-addon-api/blob/main/doc/threadsafe.md) to safely invoke these functions from C++ threads without hindering the Node.js event loop.\n\n- **Batch Processing of JavaScript Callbacks:**  \n  For operations like `countIf`, `copyIf`, `sortComp`, and `partialSortComp`, the addon utilizes batch processing to minimize overhead. This involves converting per-element predicates/comparators into batch versions using provided helper functions (`elementPredicateToMask`, `elementComparatorToKeys`), allowing the addon to handle large datasets efficiently.\n\n- **Flexible Configuration:**  \n  Adjust parameters such as `threadCount`, `threshold`, `logLevel`, and more through a JSON configuration object to tailor the addon's performance to your system and application needs.\n\n- **Robust Error Handling:**  \n  Receive meaningful error messages and ensure that exceptions within asynchronous operations are properly propagated to JavaScript, facilitating easier debugging and more resilient applications.\n\n- **Scalability:**  \n  Designed to handle large arrays efficiently, the addon scales well with data size and system resources, making it suitable for demanding real-time data processing applications.\n\n- **Debugging Tools:**  \n  Leverage built-in logging and integrate with debugging tools like `nano` and `gdb` within Docker containers to troubleshoot both JavaScript and native C++ components effectively.\n\n---\n\n## Architecture Overview\n\nThe **HPX Node.js Addon** operates through a well-defined architecture that ensures efficient integration between JavaScript and HPX's C++ runtime. Here's an in-depth look at its core components:\n\n### Node-API Integration\n\n- **Node-API (N-API):**  \n  The addon is built using [Node-API](https://nodejs.org/api/n-api.html), providing a stable and ABI-compatible interface for building native addons in C++. This ensures that the addon remains compatible across different Node.js versions without requiring recompilation.\n\n- **Function Registration:**  \n  Functions like `sort`, `count`, `copyIf`, `sortComp`, etc., are registered as JavaScript-callable functions. Each function returns a `Promise`, enabling asynchronous execution and seamless integration with JavaScript's async/await patterns.\n\n### Asynchronous Execution with HPX\n\n- **HPX Runtime Initialization:**  \n  The addon initializes the HPX runtime in a background thread using the `initHPX` function. This ensures that HPX's parallel execution capabilities are available without blocking the main Node.js thread.\n\n- **Parallel Algorithms:**  \n  When a JavaScript function like `hpxaddon.sort()` is invoked, the addon schedules the corresponding HPX parallel algorithm (e.g., `hpx::sort`) to run asynchronously. These operations are executed across multiple HPX threads, leveraging multi-core architectures for enhanced performance.\n\n- **Promise-Based API:**  \n  Each asynchronous operation returns a `Promise` that resolves with the result once the HPX task completes. This design keeps the Node.js event loop responsive, even during intensive computations.\n\n### ThreadSafeFunctions and JavaScript Callbacks\n\n- **ThreadSafeFunctions (TSFNs):**  \n  For operations requiring custom JavaScript predicates or comparators (e.g., `countIf`, `copyIf`, `sortComp`), the addon uses TSFNs to safely call back into JavaScript from C++ threads. This mechanism ensures thread safety and prevents potential data races or corruption.\n\n- **Batch Processing Strategy:**  \n  To minimize the overhead of multiple TSFN calls, the addon employs a batch processing approach:\n  1. **Batch Conversion:** Convert per-element JavaScript predicates/comparators into batch-processing functions using helper functions (`elementPredicateToMask`, `elementComparatorToKeys`).\n  2. **Single Invocation:** The batch function is called once with the entire data array, returning a mask (`Uint8Array`) or keys (`Int32Array`).\n  3. **Efficient Processing:** The addon uses the returned mask or keys in C++ to perform the desired operation without invoking JavaScript functions for each element.\n\n### Data Conversion and Memory Management\n\n- **Typed Arrays:**  \n  The addon primarily works with `Int32Array` for input and output, mapping them to `std::vector\u003cint32_t\u003e` in C++. This direct mapping avoids unnecessary data copying, ensuring efficient memory usage.\n\n- **Memory Handling:**  \n  - **Input Data:**  \n    When a JavaScript `Int32Array` is passed to the addon, it is mapped to a C++ vector for processing.\n  \n  - **Output Data:**  \n    Results are returned as new `Int32Array` instances, created from C++ vectors after processing. This ensures that data flows seamlessly between JavaScript and C++ without manual intervention.\n\n- **Shared Pointers:**  \n  The addon uses `std::shared_ptr\u003cstd::vector\u003cint32_t\u003e\u003e` to manage data lifetimes, especially when dealing with asynchronous HPX tasks. This ensures that data remains valid throughout the operation's lifecycle.\n\n### Logging and Debugging\n\n- **Custom Logger:**  \n  The addon includes a custom logging system controlled by configuration options (`loggingEnabled`, `logLevel`). Logs provide insights into the HPX runtime lifecycle, async operations, and TSFN callbacks.\n\n- **Debugging Tools:**  \n  Within Docker containers, developers can use tools like `nano` for editing JavaScript files and `gdb` for debugging native C++ code. Detailed logging combined with these tools facilitates effective troubleshooting.\n\nFor a deeper dive into each architectural component, refer to the [Architecture](./docs/Architecture.md) document.\n\n---\n\n## Installation \u0026 Setup\n\nBuilding and setting up the **HPX Node.js Addon** can be accomplished either locally or using Docker. Both methods are supported, but building with Docker is **recommended** for consistency and ease of setup.\n\n### Building Locally\n\n**Prerequisites:**\n\n- **Node.js v20 or Newer:**  \n  Ensure that you have Node.js version 20 or later installed on your system.\n\n- **HPX Installed:**  \n  HPX should be installed in `/usr/local/hpx`. You can follow the [HPX Installation Guide](https://hpx-docs.stellar-group.org/latest/html/index.html#installation) for manual installation.\n\n- **C++17 Toolchain:**  \n  A working C++17 compiler and related build tools are required to compile the addon.\n\n**Steps:**\n\n1. **Clone the Repository:**\n\n   ```bash\n   git clone https://github.com/brakmic/hpx-nodejs-addon.git\n   cd hpx-nodejs-addon\n   ```\n\n2. **Navigate to the Addon Directory:**\n\n   The addon source code is located in the `addon` folder.\n\n   ```bash\n   cd addon\n   ```\n\n3. **Install Dependencies and Build the Addon:**\n\n   ```bash\n   npm install\n   ```\n\n   This command executes `node-gyp rebuild`, compiling the C++ addon. Ensure that all prerequisites are met to avoid build failures.\n\n4. **Initialize HPX in Your Application:**\n\n   Before using any addon functions, initialize HPX as shown in the [Usage Examples](#usage-examples-quick-start) section.\n\n**Note:** For detailed instructions, refer to the [Bulding](./docs/Building.md) guide.\n\n### Building with Docker (Recommended)\n\nUsing Docker simplifies the setup process by encapsulating all dependencies and build steps within Docker images. This ensures a consistent and reproducible environment across different development machines.\n\n**Prerequisites:**\n\n- **Docker Installed:**  \n  Ensure that Docker is installed and running on your system. You can download Docker from [here](https://www.docker.com/get-started).\n\n**Steps:**\n\n1. **Clone the Repository:**\n\n   ```bash\n   git clone https://github.com/brakmic/hpx-nodejs-addon.git\n   cd hpx-nodejs-addon\n   ```\n\n2. **Build the Addon Docker Image:**\n\n   ```bash\n   docker build -t brakmic/hpx-nodejs-addon-builder:v0.1 -f addon.Dockerfile .\n   ```\n\n   This command builds the addon using the `addon.Dockerfile`, resulting in a Docker image tagged as `brakmic/hpx-nodejs-addon-builder:v0.1` that contains the compiled `hpxaddon.node` binary.\n\n3. **Build the Application Docker Image:**\n\n   ```bash\n   docker build -t brakmic/hpx-nodejs-app:latest -f app.Dockerfile .\n   ```\n\n   This builds the application image tagged as `brakmic/hpx-nodejs-app:latest`, which includes scripts for running the application (`index.mjs`), benchmarking (`benchmark.mjs`), and tests.\n\n---\n\n## Using the Addon\n\nAfter building the addon, whether locally or using Docker, you can utilize it in your applications. Below are instructions for both methods.\n\n### Running Locally\n\n1. **Navigate to the Addon Directory:**\n\n   Ensure you're in the `addon` directory where the addon was built.\n\n   ```bash\n   cd addon\n   ```\n\n2. **Create or Modify JavaScript Scripts:**\n\n   Use your preferred editor to create or edit JavaScript files that utilize the addon. For example:\n\n   - **Edit `index.mjs`:**\n\n     ```bash\n     nano index.mjs\n     ```\n\n     Add your application logic using the addon functions.\n\n   - **Edit `benchmark.mjs`:**\n\n     ```bash\n     nano benchmark.mjs\n     ```\n\n     Add benchmarking scripts to compare addon performance with native JavaScript implementations.\n\n3. **Run the Application:**\n\n   ```bash\n   node index.mjs\n   ```\n   ![hpx_app_run](./gifs/hpx_app_run.gif)\n\n   Or run benchmarks:\n\n   ```bash\n   npm run benchmark\n   ```\n   ![hpx_benchmark_run](./gifs/hpx_benchmark_run.gif)\n\n4. **Run Tests:**\n\n   ```bash\n   npm test\n   ```\n\n   ![hpx_test_run](./gifs/hpx_test_run.gif)\n\n### Using Docker\n\nUsing Docker abstracts away the complexities of managing dependencies and environments. Here's how to run your application within Docker.\n\n1. **Run the JavaScript Application (`index.mjs`):**\n\n   ```bash\n   docker run --rm brakmic/hpx-nodejs-app:latest\n   ```\n\n   This command starts the `hpx-nodejs-app` container, runs `index.mjs` using the compiled addon, and outputs the results.\n\n2. **Run the Benchmark (`benchmark.mjs`):**\n\n   ```bash\n   docker run --rm brakmic/hpx-nodejs-app:latest npm run benchmark\n   ```\n\n   This executes the benchmarking script inside the Docker container, comparing HPX-based operations with native JavaScript implementations.\n\n3. **Run Tests:**\n\n   ```bash\n   docker run --rm brakmic/hpx-nodejs-app:latest npm test\n   ```\n\n   Or directly run a specific test script:\n\n   ```bash\n   docker run --rm brakmic/hpx-nodejs-app:latest node test/hpx-addon.test.mjs\n   ```\n\n4. **Access the Container's Shell for Debugging:**\n\n   If you need to modify scripts or debug within the container:\n\n   ```bash\n   docker run -it brakmic/hpx-nodejs-app:latest /bin/bash\n   ```\n\n   Inside the container, you can use `nano` to edit files or `gdb` to debug native addon issues.\n\n---\n\n## Configuration Options\n\nYou can configure the HPX runtime by passing a configuration object to `initHPX`. Here's the available configuration options:\n\n```js\nawait hpxaddon.initHPX({\n  executionPolicy: 'par',       // Execution policy: \"seq\", \"par\", \"par_unseq\"\n  threshold: 10000,              // Threshold for task granularity (smaller arrays run sequentially)\n  threadCount: 4,                // Number of HPX threads to spawn\n  loggingEnabled: true,          // Enable or disable logging\n  logLevel: 'info',              // Logging level: \"debug\", \"info\", \"warn\", \"error\"\n  addonName: 'hpxaddon'          // Name of the addon (optional)\n});\n```\n\n**Configuration Details:**\n\n- **executionPolicy:**  \n  Determines how algorithms are executed.  \n  - `\"seq\"`: Sequential execution.  \n  - `\"par\"`: Parallel execution.  \n  - `\"par_unseq\"`: Parallel unsequenced execution.\n\n- **threshold:**  \n  Sets the threshold for task granularity. Arrays smaller than this value will execute sequentially to avoid parallel overhead.\n\n- **threadCount:**  \n  Specifies the number of HPX threads to spawn, typically aligned with the number of CPU cores for optimal performance.\n\n- **loggingEnabled \u0026 logLevel:**  \n  Control logging behavior. Enable logging and set the desired verbosity level to monitor internal operations and debug issues.\n\nFor a comprehensive list and explanation of configuration options, see [Configuration](./docs/Configuration.md).\n\n---\n\n## Usage Examples (Quick Start)\n\nHere's a quick example to get you started with the HPX Node.js Addon:\n\n```js\nimport { createRequire } from 'module';\nconst require = createRequire(import.meta.url);\nconst hpxaddon = require('./addons/hpxaddon.node');\n\n(async () =\u003e {\n  // Initialize HPX\n  await hpxaddon.initHPX({\n    executionPolicy: 'par',\n    threshold: 10000,\n    threadCount: 4,\n    loggingEnabled: true,\n    logLevel: 'debug'\n  });\n\n  // Sorting an Int32Array\n  const arr = Int32Array.from([5, 3, 8, 1, 9]);\n  const sorted = await hpxaddon.sort(arr);\n  console.log('Sorted Array:', sorted); // Int32Array [1, 3, 5, 8, 9]\n\n  // Counting occurrences of a value\n  const data = Int32Array.from([1, 2, 2, 3, 2, 4, 2]);\n  const countOf2 = await hpxaddon.count(data, 2);\n  console.log(`Count of 2: ${countOf2}`); // Output: Count of 2: 4\n\n  // Finalize HPX before exiting\n  await hpxaddon.finalizeHPX();\n})();\n```\n\n**Note:** Ensure that you call `finalizeHPX()` to gracefully shut down the HPX runtime when your application is terminating.\n\n---\n\n## Debugging\n\nEffective debugging ensures that your application runs smoothly and efficiently. The **HPX Node.js Addon** provides tools and strategies to debug both JavaScript and native C++ components.\n\n### Editing Files with Nano\n\nTo modify JavaScript files within the Docker container:\n\n1. **Access the Container's Shell:**\n\n   Launch a bash shell inside the `brakmic/hpx-nodejs-app` container:\n\n   ```bash\n   docker run -it brakmic/hpx-nodejs-app:latest /bin/bash\n   ```\n\n2. **Edit JavaScript Files Using Nano:**\n\n   - **Edit `index.mjs`:**\n\n     ```bash\n     nano index.mjs\n     ```\n\n   - **Edit `benchmark.mjs`:**\n\n     ```bash\n     nano benchmark.mjs\n     ```\n\n   After making changes, save your edits by pressing `Ctrl + O`, then exit `nano` with `Ctrl + X`.\n\n### Debugging with GDB\n\nWhen encountering crashes or unexpected behavior in the native addon, **GNU Debugger (GDB)** can be invaluable for diagnosing issues.\n\n1. **Access the Container's Shell:**\n\n   ```bash\n   docker run -it brakmic/hpx-nodejs-app:latest /bin/bash\n   ```\n\n2. **Start GDB with the Desired Script:**\n\n   - **Debug `index.mjs`:**\n\n     ```bash\n     gdb --args node index.mjs\n     ```\n\n   - **Debug `benchmark.mjs`:**\n\n     ```bash\n     gdb --args node benchmark.mjs\n     ```\n\n3. **Run the Script Within GDB:**\n\n   Inside the GDB prompt, start execution by typing:\n\n   ```gdb\n   run\n   ```\n\n4. **Handling Crashes:**\n\n   If the application crashes, GDB will catch the signal. To obtain a detailed backtrace, enter:\n\n   ```gdb\n   bt full\n   ```\n\n   This command provides a comprehensive stack trace, helping you identify where the crash occurred.\n\n5. **Additional GDB Commands:**\n\n   - **Set Breakpoints:**\n\n     ```gdb\n     break main\n     ```\n\n   - **Step Through Code:**\n\n     ```gdb\n     step\n     ```\n\n   - **Continue Execution:**\n\n     ```gdb\n     continue\n     ```\n\n   - **Inspect Variables:**\n\n     ```gdb\n     print variableName\n     ```\n\n   For more advanced debugging techniques, refer to the [GDB Documentation](https://www.gnu.org/software/gdb/documentation/).\n\n**Note:** Debugging native addons with GDB is most effective when the addon is built with debugging symbols. Ensure that your build configuration includes debug information to facilitate meaningful debugging sessions.\n\n---\n\n## Troubleshooting\n\nEncountering issues is a natural part of development. Here's how to address common problems with the **HPX Node.js Addon**:\n\n- **Check Logs for Detailed Information:**\n  - Enable `loggingEnabled` and set `logLevel` to `debug` to view detailed internal operations.\n\n- **HPX Fails to Start:**\n  - Ensure HPX is correctly installed and that the `LD_LIBRARY_PATH` is properly set.\n  - Verify that all dependencies are installed and that there are no version mismatches.\n\n- **Missing Libraries at Runtime:**\n  - Confirm that `COPY --from=...` steps in the `app/Dockerfile` are correct.\n  - Ensure that `LD_LIBRARY_PATH` includes the directories where HPX and other dependencies are installed.\n\n- **Performance Overhead:**\n  - Running inside Docker might introduce slight overhead. Allocate sufficient CPU and memory resources to the Docker daemon for accurate benchmarks.\n\n- **Debugger Tools Not Found:**\n  - If `nano` or `gdb` are not available within the container, ensure they are installed via the `app/Dockerfile`:\n  \n    ```dockerfile\n    RUN apt-get update \u0026\u0026 apt-get install -y nano gdb\n    ```\n  \n  - Rebuild the `app/Dockerfile` image after making this change.\n\n- **Invalid Input Types:**\n  - Ensure that all inputs to addon functions are of the expected types. For example, `sort` expects an `Int32Array`.\n  - Use try-catch blocks to handle and log errors gracefully.\n\n- **Predicate/Comparator Errors:**\n  - Ensure that predicate functions return a `Uint8Array` and comparator functions return an `Int32Array` of keys.\n  - Verify that batch functions are correctly implemented to avoid mismatched array lengths or types.\n\nFor unresolved issues, consider consulting the [Documentation](./docs/Troubleshooting.md) or reaching out to the community through [Issues](https://github.com/brakmic/hpx-nodejs-addon/issues).\n\n---\n\n**Additional Resources:**\n- [Architecture](./docs/Architecture.md)\n- [Benchmarking](./docs/Benchmarking.md)\n- [Building](./docs/Building.md)\n- [Configuration](./docs/Configuration.md)\n- [Docker](./docs/Docker.md)\n- [Examples](./docs/Examples.md)\n- [Internals](./docs/Internals.md)\n- [Predicates](./docs/Predicates.md)\n- [Testing](./docs/Testing.md)\n\n## License\n\nThis project is distributed under the MIT License.
