the vortex induced vibration is an important problem for the offshore industry, due to the frequent use of structures, such as risers and umbilicals. In the last decade, the use of numerical methods to study the vortex induced vibration has increased. Some disagreement between numerical and experimental results has been verified in the literature. In the present work, the numerical model solves the Reynolds average Navier-Stokes equations using an upwind and a Total Variation Diminishing (TVD) conservative scheme, written in curvilinear coordinates. the turbulent flow in the wake of the cylinder has been modelled using the k - epsilon model. the cylinder is supported by a spring and a damper and free to vibrate in the transverse direction. Results obtained for phase angle, amplitude, frequency, and lift coefficient are compared to experimental data from Morse et al. [1]. the results indicate that the two dimensional simulation represents better the behaviour of cylinder displacement obtained experimentally using the unattached or attached end plate setup used by Morse et al. [1]. these results suggest that some difference between experimental and numerical data could be associated withthe end condition used in the experiments. For the case using the unattached or attached end plate the difference in the peak amplitude between experimental and present results seems to be related withthe initial condition adopted.

We present the agent programming language POGTGolog, which integrates explicit agent programming in Golog with game-theoretic multi-agent planning in partially observable stochastic games. It deals withthe case of one team of cooperative agents under partial observability, where the agents may have different initial belief states and not necessarily the same rewards. POGTGolog allows for specifying a partial control program in a high-level logical language, which is then completed by an interpreter in an optimal way. To this end, we define a formal semantics of POGTGolog programs in terms of Nash equilibria, and we specify a POGTGolog interpreter that computes one of these Nash equilibria. We illustrate the usefulness of POGTGolog along a rugby scenario.

Offloading computations to multiple GPUs is not an easy task. It requires decomposing data, distributing computations and handling communication manually. GPU drop-in libraries (which require no program rewrite) have made it easy to offload computations to multiple GPUs by hiding this complexity inside library calls. Such encapsulation prevents the reuse of data between successive kernel invocations resulting in redundant communication. this limitation exists in multi-GPU libraries like CUBLASXT. In this paper, we introduce SemCache++, a semantics-aware GPU cache that automatically manages communication between the CPU and multiple GPUs in addition to optimizing communication by eliminating redundant transfers using caching. SemCache++ is used to build the first multi-GPU drop-in replacement library that (a) uses the virtual memory to automatically manage and optimize multi-GPU communication and (b) requires no program rewriting or annotations. Our caching technique is efficient;it uses a two level caching directory to track matrices and sub-matrices. Experimental results show that our system can eliminate redundant communication and deliver performance improvements over multi-GPU libraries like StarPU and CUBLASXT.
