What is High Performance Computing
Some problems look simple on the surface, but they hide an uncomfortable truth: one computer just isn’t enough.
Think about weather prediction. It’s not “will it rain tomorrow?” It’s: how do temperature, pressure, humidity, wind, oceans, mountains, and sunlight interact over time—across an entire planet—minute by minute?
Or consider Google Maps traffic updates. You’re not only asking for the shortest route. You’re asking for the best route right now, while accidents happen, roads close, traffic lights change, and millions of other drivers make decisions at the same time.
Even Netflix recommendations are a massive puzzle: millions of users, huge libraries of content, and constantly changing behavior. The system has to learn patterns quickly and update predictions continuously.
These aren’t “hard” because the idea is complicated. They’re hard because they’re too big, too fast, or too complex for one machine to keep up.
So here’s the question that leads to High Performance Computing:
What if thousands of computers could work together like one?
