UC Berkeley to join the Open Source Modelica Consortium

At the prompting of Professor Edward A. Lee, UC Berkeley is to join the Open Source Modelica Consortium (OSMC).  The purpose of the OSMC is to support long term development of OpenModelica and its associated tools and libraries.  OpenModelica is an open source implementation of the Modelica language that is used in academia and industry for modeling, compilation and simulation. Professor Lee is interested in how the Functional Mock-up Interface (FMI) can be used to co-simulate and exchange models.  The FMI standard effort is being led by a number of Modelica vendors.  In particular, Professor Lee is applying his expertise in the semantics of heterogeneous models of computation and how they handle the notion of time.  These issues are of concern when different modeling tools exchange information.  The OSMC is led by Professor Peter Fritzson of Link√∂ping University.

"Futuristic UC Berkeley operating system uniquely controls discrete 'manycore' resources"


A Network World article by Ellen Messmer, "Futuristic UC Berkeley operating system uniquely controles discrete 'manycore' resources," describes the Tesselation operating system by Professor John Kubiatowicz.  The article states:

"According to Kubiatowicz, Tessellation -- which is a math term for how shapes can be arranged to fill a plane without any gaps -- is an innovative OS that looks to define resources such as bandwidth for cloud storage, latency to response, and requests for database services in a continuous adaptive manner based on its concept of resource containers."

Professor Kubiatowicz' work is sponsored in part by the TerraSwarm Research Center.  One of the intended outcomes of TerraSwarm is SwarmOS, which will provide a swarm of services at the edge of the cloud.

The article also mentions Professor Edward A. Lee's presentation on the Internet of Things and Professor Alberto Sangiovann-Vincentelli's closing keynote.  Both presentations mentioned the TerraSwarm Research Center.
