Threading Building Blocks (TBB) is a C++ threading library that makes multicore programming more accessible. We considered TBB for web application developers working in script languages.
Many websites require a non-trivial amount of per-request processing in the application layer, to retrieve, consolidate or manipulate data. Achieving better performance at this level improves response times and the [...]

In a previous article (We Need More than Multicore), Wolfgang discussed the evolution of multicore processors, and the dramatic effect this processor shift can have on compute cluster performance. Clearly, leveraging a lot of cores will require that many concurrent tasks – as opposed to a single massively parallel [...]

For decades, scientists have dreamed of building computer systems that could replicate the human brain’s talent for learning new tasks.
MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain’s neurons adapt in response to new information. This phenomenon, known [...]

This is not to say that compilers can automatically parallelize code. I would however really like to see that happen and here is an interesting and reliable way to parallelize operations. If a compiler can use this method of thinking then it can also be used as hints for developers writing code today.

Some application developers might need to port applications from 8-bit or 16-bit microcontrollers to the Cortex-M0. By moving from these architectures to the Cortex-M0, often you can get better code density, higher performance, and lower power consumption.
Common Modifications: When porting applications from these microcontrollers to the Cortex-M0, the modifications of [...]
