Why Parallel Computing?
The Power Wall
The Single-Core Performance Wall
“The major processor manufacturers and architectures, from Intel and AMD to Sparc and PowerPC, have run out of room with most of their traditional approaches to boosting CPU performance. Instead of driving clock speeds and straight-line instruction throughput ever higher, they are instead turning en masse to hyperthreading and multicore architectures.”

Entertainment Industry
Performance Challenge
Advanced research has moved beyond the capacity of a single computer for detailed multi-level simulations, data analysis, and large-scale computations.

Examples of Parallel Computing
Summary
• The computers of today, and tomorrow, have tremendous processing power that require parallel programming to fully utilize.
• There are significant differences between sequential and parallel programming, that can be challenging.
• With early exposure to these differences, students are capable of achieving performance improvements with multicore programming.
