42. On bad web interfaces

Programming/Web

Today I have encountered the following error message in a major web site: However: there was no warning on the web page about this limitation (e.g. "type up to 3000 chars") there was no warning while typing that I was entering too much...

43. Returning buffers with C++ and Boost

Programming/OOD / OOP

In the article comparing CPU and GPU implementations of the median filter, the class was designed to receive image buffers with the AddSample method and return a pointer to the image buffer with the GetMedianImage method: class TM_CPURefImpl : ...

44. Quexal MMX goes freeware

Programming/Software

Back in 2000, Quexal changed the way programmers had to deal with MMX programming. A friendly user interface simplified building parallel versions of algorithms, an optimizing compiler made sure that the resulting code would run fast, and a visual...

55. Multi-thread loops with Intel TBB

Programming/Multi-thread

A new article about using Intel TBB is here. It contains examples using C++ lambdas and joining multi-threaded loops with SIMD code In this article we will transform a plain C loop into a multi-threaded version using Intel Thread Building Blocks...

56. Different types of parallel loops with Intel TBB, SSE2, SSSE3 and Visual C++ 2012

Programming/Multi-thread

This is not the first article on this site that discusses how to use the Intel Thread Building Blocks library to spread the computation of an image-processing kernel over multiple threads: the article named "Multi thread loops with Intel TBB" showed...

57. SSE2 64-bit FP instructions

Programming/SIMD

In the introduction we have outlined the applications that require 64-bit precision, scientific simulations and CAD/CAM being notable examples. However, the transition from normal scalar code to 64-bit floating-point SSE2 code is complex and it...

58. SSE2 and MMX

Programming/SIMD

I'm quite sure that Intel would not like to see SSE2 named 128-bit MMX. In fact, MMX has a bad reputation: the Intel marketing hype pushed it as an universal solution to multimedia requirements, but at the same time the gaming industry switched...

59. 3DNow!

Programming/SIMD

The latest trend in PC games is 3D graphics: during the past few years, almost all kinds of games have turned to 3D graphics, greatly increasing the demand of processors with strong floating-point performance, because the front end of a typical...
