GPU Manager System

Shared WebGPU resource management and coordination for all GPU-accelerated systems.

System Overview

The GPU Manager System manages the WebGPU instance, device initialization, and resource sharing across all systems that require GPU computation or rendering.

Key Challenge: Coordinate GPU resource usage across multiple systems (Physics, Reactions, Renderer) while maintaining performance and preventing resource conflicts.

Core Responsibilities

  • WebGPU device initialization and capability detection
  • GPU resource allocation and memory management
  • Compute pipeline coordination between systems
  • Error handling and recovery for GPU operations
  • Performance monitoring and resource utilization tracking

Resource Management

Shared Resources

  • WebGPU Device: Single device instance shared across all systems
  • Buffer Pools: Reusable buffer allocation for different data types
  • Texture Management: Coordinate texture creation and lifecycle
  • Compute Queue: Prioritized command queue for GPU operations

System Integration

  • Physics System: Provides compute shaders for collision and movement
  • Reactions System: Manages rule compilation and execution shaders
  • Renderer: Coordinates rendering pipeline and display
  • Core System: Integrates with texture ping-ponging and memory management

Technical Features

Device Management

  • Automatic Fallback: Handle WebGPU unavailability gracefully
  • Capability Detection: Query and adapt to GPU limitations
  • Error Recovery: Robust handling of GPU context loss
  • Performance Profiling: Built-in GPU timing and resource monitoring

Resource Coordination

  • Allocation Tracking: Monitor buffer and texture usage across systems
  • Memory Optimization: Efficient sharing and reuse of GPU resources
  • Priority Management: Coordinate competing GPU workloads
  • Synchronization: Ensure proper ordering of GPU operations

Integration Points
