Accelerated graphics cards, or Graphics Processing Units (GPUs), have become ubiquitous in recent years. On the right kinds of problems, GPUs greatly surpass CPUs in terms of raw performance. However, because they are difficult to program, GPUs are used only for a narrow class of special-purpose applications; the raw processing power made available by GPUs(More)
In Pakistan, groundwater is the second largest source of irrigated agriculture. In Sindh province of Pakistan, fresh groundwater lenses are overlying saline groundwater. In order to pump fresh water, shallow skimming tubewells are being used in Sindh. Due to little awareness, the farmers are installing more traditional tubewells that penetrate into higher(More)
Heterogeneous multi-core and streaming architectures such as the GPU, Cell, ClearSpeed, and Imagine processors have better power/ performance ratios and memory bandwidth than traditional architec-tures. These types of processors are increasingly being used to accelerate compute-intensive applications. Their performance advantage is achieved by using(More)
