GPU Computing in Discrete Optimization Part II: Survey Focused on Routing Problems

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1021700

In many cases there is still a large gap between the performance of current optimization technology and the requirements of real-world applications. As in the past, performance will improve through a combination of more powerful solution methods and a general performance increase of computers. These...

Graphics processing unit (GPU) programming strategies and trends in GPU computing

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1004301

In this article, we have given an overview of hardware and traditional optimization techniques for the GPU. We have furthermore given a step-by-step guide to profile driven development, in which bottlenecks and possible solutions are outlined. The focus is on state-of-the-art hardware with accompany...

A Framework for OpenGL Client-Server Rendering

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1003537

We present a software framework that facilitates the development of OpenGL applications utilizing the limited GPU capacities of a portable client in combination with the high-end rendering hardware on a server. The resulting webapplication uses standard technologies and can be run on a wide variety ...

“The Beach Law” does not hold any more - Discrete optimization needs heterogeneous computing

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1272774

Modern PCs are parallel and heterogeneous, with a growing number of cores for task parallelism and ever more powerful data parallel accelerators. The glory days when you could go to the beach for two years, and your sequential optimization program would run twice as fast on a  new PC when you got ba...

Hetereogeneous Spline Surface Intersections

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1452068

While the PC just a few years ago included only one single-core CPU and a fixed functionality graphics card, the current commodity PC is a heterogeneous system, equipped with both a multi-core CPU and a fully programmable graphics processing unit (GPU). This change has given the commodity PC one to ...

GPU Programming Strategies

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1272509

In recent years, we have seen an abrupt halt in the traditional increase in CPU frequency, where new processors have the same frequency but an increasing number of cores. The reason for this abrupt change is that we have reached the limit to the power density chips can withstand using current coolin...
