    The advent of powerful cosmological surveys demands a new generation of high-precision, large-volume, and high dynamic range simulations of structure formation in the Universe. Key aims of these simulations are understanding why the expansion of the Universe is accelerating and what dark matter is made of. The availability of Roadrunner, the world's first petaflop platform, led us to develop a new... View full abstract»

    Much success has been achieved using GPUs to accelerate existing applications that are highly data parallel, or that are dominated by small, intense computational kernels. What are the prospects for porting existing large scientific models that do not fit this mold? We take an expensive routine from the CAM atmosphere model, and port it to a GPU using CUDA. We use the experience gained as a guide ... View full abstract»

    Graphical processing units are now being used with dramatic effect to accelerate quantum chemistry applications. The authors give a brief introduction to electronic structure methods and describe their efforts to accelerate a correlated quantum chemistry code. They propose and analyze two new tools for accelerating matrix-multiplications where single-precision accuracy is insuffcient. View full abstract»

    The fun all began in May of 1999, when VMware launched VMware Workstation, a product that lets you run multiple operating systems simultaneously on your desktop computer. In truth, the story begins much earlier with the VM OS concept, which was pioneered (like many things) by IBM in 1960 but eventually perfected by others. The idea behind virtualization is simple. You can run multiple OSs simultan... View full abstract»

    Many engineers practice in areas that affect the public health, safety, and welfare, and each US jurisdiction (states and territories) has licensing laws to ensure that these engineers meet some level of minimal competence. Such competence might be defined as the minimum threshold of knowledge to ensure protection of the public. This licensing process wasn't designed to grade a candidate's ability...

    A new exact representation of the error function of real arguments justifies an accurate and simple analytical approximation. Two of the most widely used functions in physical sciences are the error function erf(x) and its related complimentary error function erfc(x). These functions occur extensively in problems relating to diffusion, heat conduction, and probability. When the argument x is real,... View full abstract»
