Abstract We present a GPU-accelerated cosmological simulation code, PhotoNs-GPU, based on an algorithm of Particle Mesh Fast Multipole Method (PM-FMM), and focus the GPU utilization optimization. A proper interpolated method for truncated gravity is introduced to speed up special functions in kernels. verify code mixed precision different levels theinterpolated GPU. run with single roughly two ...

Todays, there are many studies in complicated computation and big data processing by using the high performance computability of GPU. Tesla K20X recently announced by NVIDIA provides 3.95 TFLOPS in precision floating point performance [1]. The performance of K20X is 10 times higher than Intel’s high-end CPUs. Due to the high performance computability of GPU, K20X was adapted to Titan, the first...

ER GI A N ew s vo l. 4 nr 2 • 2 00 1 9 A rapidly accessible new source of woodfuel for local people could be the small patches of eucalyptus planted by Kinyara on their estate in areas not suitable for sugarcane. Originally these trees were planted to discourage illegal homes being built on the land. Using them as woodfuel would give them a more positive function. Furthermore, government polici...

Early marriage, defined as marriage before the age of 18, is mainly practiced in sub-Saharan Africa and South Asia, where over one third of African girls and nearly a half of South Asian girls are married during childhood. In subSaharan Africa, the highest rates of child marriage are found in West Africa, in countries such as Niger, Chad and Mali. However, in East Africa, the numbers of girls m...

Mali is located in the Sahel region of West Africa, to the south-west of Algeria and north of Burkina Faso and Niger (Figure 1). It has a large area of some 1.24 million square kilometres. The terrain is dominated by flat or rolling sand-capped plains in the north and savannah in the south, although rugged hills occur in the north-east. Elevation varies from the highest point at Hombori Tondo (...

Graphics processing units (GPUs) are attractive to the generalpurpose computing (GPGPU) beyond the graphics purpose. Sharing GPUs among such GPGPU applications is a key requirement especially for cloud platforms whose resources are utilized by various cloud users. However, consolidating recent GPU applications, referred to as GPU eaters, on a GPU poses a new challenge. Such advanced application...

The analysis of feedback effects between continental surfaces and the atmosphere is a key element in the understanding of African monsoon dynamics. For this reason, the monitoring of surface parameters, in particular soil moisture, is essential. Satellite remote sensing appears to be the most suitable means of obtaining data relevant to such parameters. The present paper presents the results of...
