+# Cross-Platform Xcecd Process
+
+This is a cross-platform process manager implementation in C that supports both Linux and Windows platforms. The xcecd provides the following features:
+
+- Sending status to the remote controller module at port 6789 and receive job requests
+- Maintains a configurable thread pool for request processing
+- Periodically collects and updates system resource status
+- Manages child processes spawned from received commands
+- Caches job status information
+- Uses Unix Domain Sockets for communication between the main process and worker processes
+
+## Building
+
+### Prerequisites
+
+- C compiler with C11 support
+- Windows: Visual Studio
+- Linux: GCC and development tools
+
+### Build Instructions
+
+On Linux
+```bash
+make
+```
+
+On Windows
+```bash
+nmake
+```
+
+## Configuration
+
+The xcecd can be configured through the following parameters in `main.c`:
+
+- `thread_pool_size`: Number of threads in the thread pool (default: 4)
+- `resource_update_interval`: Interval for updating system resource status in seconds (default: 1)
+- `job_status_update_interval`: Interval for updating job status in seconds (default: 1)
+- `port`: Port number to listen on (default: 7869)
+- `acct_file_path`: Path to the accounting file (default: `/tmp/xcecd.acct`)
+- `log_file_path`: Path to the log file (default: `/tmp/xcecd.log`)
+- `domain_sock_path`: Path to the Unix Domain Socket file (default: `/tmp/xcecd.sock`)
+- `remote_host`: Remote server address (default: `lchen02`)
+- `remote_port`: Remote server port (default: 6789)
+- `update_interval`: Interval for sending status updates to the remote server (default: 1 second)
+
+## Usage
+
+### Starting the Xcecd
+
+On Windows:
+```bash
+xcecd.exe
+```
+
+On Linux:
+```bash
+./xcecd
+```
+
+## Features
+
+1. **Cross-Platform Support**
+   - Works on both Windows and Linux
+   - Abstracts platform-specific implementations
+
+2. **Thread Pool**
+   - Configurable number of worker threads
+   - Efficient request handling
+
+3. **System Monitoring**
+   - CPU usage monitoring
+   - Memory usage monitoring
+   - Disk space monitoring
+
+4. **Process Management**
+   - Spawns child processes for received commands
+   - Tracks process status
+   - Manages process lifecycle
+
+5. **Network Communication**
+   - TCP socket-based communication
+   - Simple text-based protocol
+
+6. **Unix Domain Socket Communication**
+   - Uses Unix Domain Sockets for communication between the main process and worker processes
+
+## Architecture
+
+The xcecd is composed of several key components:
+
+- **Main Process**: Coordinates all components and manages the lifecycle
+- **Thread Pool**: Handles concurrent request processing
+- **System Monitor**: Collects and updates system resource information
+- **Process Manager**: Manages child processes and their status
+- **Network Handler**: Handles network communication and request receiving
+- **Resource Sync**: Synchronizes and aggregates resource collection thread, system monitor, and job information
