What is Parallel Computing?
Simply, doing multiple tasks simultaneously
Task-Parallel computing does different tasks concurrently
Reading email, playing music, and surfing the web are all separate tasks
In a multicore system, these can execute simultaneously
Data-Parallel computing does the same operation on a
collection of data concurrently
Adjusting the contrast of the pixels of an image
Each thread executes the same code but with different data
Classic SIMD (single-instruction, multiple-data)
GPU computing is perfect for data-parallel applications
