The AMTHA (Automatic Mapping Task on Heterogeneous Architectures) algorithm for task-to-processors assignment and the MPAHA (Model of Parallel Algorithms on Heterogeneous Architectures) model are presented. The use of AMTHA is analyzed for multicore processor-based architectures, considering the communication model among processes in use. The results obtained in the tests carried out are presen...

A study is reported into strategic IS planning (SISP) in UK organisations. The core data is derived from 70 UK organisations across private and public sectors. The study developed prior work by Earl (1993) and Segars & Grover (1999) who found that organisations used a small number of SISP approaches each with differing levels of success. This study broadly confirmed these earlier findings but s...

Nowadays the number of available processing cores within computing nodes which are used in recent clustered environments, are growing up with a rapid rate. Despite this trend, the number of available network interfaces in such computing nodes has almost been remained unchanged. This issue can lead to high usage of network interface in many workloads, especially in heavy-communicating workloads....

[1] Greater understanding of variations in firn densification is needed to distinguish between dynamic and melt-driven elevation changes on the Greenland ice sheet. This is especially true in Greenland’s percolation zone, where firn density profiles are poorly documented because few ice cores are extracted in regions with surface melt. We used georadar to investigate firn density variations wit...

Undergraduate students are increasingly engaged in developing products, technologies, and services that are commercially viable through their involvement in courses and experiential programs focused on entrepreneurship and product design. Little is known about the degree to which these activities are creating protectable intellectual property (IP) or the degree to which student involvement in t...

Since 2008, the Japanese FrameNet (JFN, http://jfn.st.hc.keio.ac.jp/) project has been annotating the Balanced Corpus of Contemporary Written Japanese (BCCWJ), the first such corpus, officially released in October 2011. This paper reports annotation results of the book genre of BCCWJ (Ohara 2011, Ohara, Saito, Fujii & Sato 2011). Comparing the semantic frames needed to annotate BCCWJ with those...

At the German wintering base Neumayer, an intensive glacio-meteorologicalprogrammehasbeen carried out during the last two decades. A completemeteorological dataset and data from surface snow samples, snow pits, firn cores and weekly accumulation measurements from a stake array are available.We first investigated the attenuation of the seasonal ̄O signal due to water-vapour diffusion in the snow...

Hardware designers are adding additional cores to chips in an attempt to improve throughput performance. These multicore systems share hardware resources at multiple levels of the system. The question is when multiple applications run on the same chip, how do they interact with the shared resources, and how do these interactions effect performance? Traditional profile based approaches that aggr...
