Interactive Steering of Supercomputing Simulation for Aerodynamic Noise Radiated from Square Cylinder.

Interactive supercomputing

MITMatlab is a system that provides users of high performance computers with an interactive, easy-to-use environment for solving their scientific and engineering problems. It is an effort to bridge the gap between scientific computing in the desktop and supercomputer worlds by providing users of parallel machines with a tool for manipulating and visualising large datasets. We believe that the m...

Radiated Noise from an Externally Blown Flap

Underwater radiated noise from modern commercial ships.

Underwater radiated noise measurements for seven types of modern commercial ships during normal operating conditions are presented. Calibrated acoustic data (<1000 Hz) from an autonomous seafloor-mounted acoustic recorder were combined with ship passage information from the Automatic Identification System. This approach allowed for detailed measurements (i.e., source level, sound exposure level...

Experimental study of the aerodynamic noise radiated by cylinders with different cross-sections and yaw angles

Vortex shedding from cylinders has been extensively studied due to its occurrence in many engineering fields. Many experimental studies reported in the literature focus on the aerodynamics of the vortex shedding process but the literature about the radiated noise is more scarce. The aim of the work presented here is to extend the available noise data. Aero-acoustic wind tunnel tests were carrie...

Interactive Supercomputing with MITMatlab

This paper describes MITMatlab, a system that enables users of supercomputers to transparently work on large data sets within Matlab. MITMatlab communicates with an external server that is responsible for storing and operating on the data. Through the use of Matlab's object oriented features, we can handle this data as though it were \in" Matlab. For example, we can type [u,s,v] = svds(a,5) in ...
