The USPTO awarded search giant Google a software method patent that covers the principle of distributed MapReduce, a strategy for parallel processing that is used by the search giant. If Google chooses to aggressively enforce the patent, it could have significant implications for some open source software projects that use the technique, including [...]

In industry surveys, more than 80% of embedded systems software developers report using either C or C++ as their primary programming language. Yet as a group, they earned a failing grade on a multiple-choice evaluation of their firmware-related C knowledge.
In December of 2007, an Embedded C Quiz was launched online as part of a redesigned [...]

Libraries play an important role in threading software to run faster on Intel multi-core platforms.
Multi-core platforms are the default computer platforms sold throughout the world. On a multi-core platform there are multiple processors contained on a single chip. That is, each chip has multiple cores that are each [...]

In the basic sequential model of programming, a computer program’s instructions are executed one at a time. Each task is performed in a specified order, and each task stands in line and must wait its turn.
This changes when the software requirements include multithreading or multiprocessing components. When parallel processing is called [...]

Traditional problems in Mutli-Processor programming
As we reached the speed-limit of serialized CPU instructions we started to add more cores. Obviously, adding more cores means we have to change how we process information. Instead of optimizing for the fastest serial processing of data, we look for ways to split the work into multiple tasks. [...]

Parallelization using threads on multiple logical processors is an attractive and effective way to optimize software. As technologies to simulate multiple processors (such as Hyper Threading) and processors containing multiple cores become the standard for even consumer level computing, the importance of parallelization becomes apparent.
To [...]

With Nvidia getting most of the attention when it comes to the use of graphics cards and GPU co-processors to boost the number-crunching capability of workstations and servers, it’s hard for Advanced Micro Devices to get a word in edgewise. Perhaps that’s why AMD waited until the holiday news dead zone to [...]

“At times threaded software requires some critical sections, mutexes or locks. Do developers always know which of the objects in their code has the most impact? If I want to examine my software to minimize the impact or restructure data to eliminate some of these synchronization objects and [...]

The Windows operating system is a preemptive and multithreaded operating system. Multithreading refers to the capability to run any number of threads concurrently. If the system is a single processor machine, Windows creates the illusion of concurrent thread execution by allowing each thread to run for a short period of time (known as [...]

“The oft-contended best simple statement is that we need ubiquitous parallelism in the classroom. Once upon a time, it was solely the lunatic fringe, programming esoteric architectures squirreled away in very special corners of the globe that cared about parallelism. In the near future, most electronic [...]

NUMA (short for “Non-Uniform Memory Access”) architectures are becoming popular in high-performance computing (HPC) scenarios. Therefore, it is very important to work with efficient and optimized memory allocators. QuickThread is a new commercial C++ multicore programming library loaded with many optimizations for NUMA architectures, bringing a new option to create high-performance parallelized code.
