GPU Acceleration For Real-Time Decision Making

What is GPU Acceleration for Real-Time Decision Making?

GPU acceleration refers to the use of Graphics Processing Units to perform computational tasks traditionally handled by Central Processing Units (CPUs). Unlike CPUs, which are optimized for sequential processing, GPUs excel at parallel processing, making them ideal for handling large-scale computations simultaneously. In the context of real-time decision-making, GPU acceleration enables systems to analyze and process data streams at lightning speed, ensuring decisions are made within milliseconds.

For example, in autonomous vehicles, GPUs process data from cameras, LiDAR, and sensors in real time to make driving decisions. Similarly, in financial trading, GPUs analyze market data to execute trades in microseconds. The ability to process data in parallel allows GPUs to outperform traditional CPUs in scenarios where speed and efficiency are critical.

Key Components of GPU Acceleration for Real-Time Decision Making
