The concept of cloudlets is consistent with the recent concept of Fog computing [10 12] which focuses on the edge for mobile users so that mobile users can access computation-intensive services via short-distance and low-delay local connections.
In appropriate applications and with specialized computing architectures they might even circumvent the bottleneck of time-consuming memory access, as computation is inherently performed with non-volatile computing states.
Adaptive hp finite element methods (FEM), in which both grid size h and local polynomial order p are dynamically altered, generate computations that require dynamic and irregular patterns of data storage, access and computation, making their parallelization very difficult.
The Nt_STM package, at its current version 2.0, gives the opportunity to access parallel computation, a new collection of objects and new Extended Hückel parameters.
When the algorithm is implemented with a 2D filter, the amount of memory access and computation for the SRP needs to be increased quadratically.
As technologies, networks and business models mature, I expect that grids will become commonplace for small and large enterprises and research institutions linking their various resources to support human communication, data access and computation.
The new techniques make it possible to access more computation power and use more energy; but the energy is still limited, and how to "reduce" the big data is still an important problem in WSN.
We thank B. Larget and A. J. Roger for access to computation facility for phylogenetic analysis, A. G. B. Simpson for providing initial sequence alignments, and A. D. Tsaousis for Greek translation.
The GenOuest computing infrastructure consists of 32 AMD Opteron bi-processor nodes (Sun V20Z) with 4 Gb of memory each and a job submission server, SGE, which manages access and computation.
