Method, system and product for decomposing a simulation model. The method comprising automatically decomposing the simulation model into a predetermined number of co-simulation components, wherein each co-simulation component is allocated to a different simulation platform, wherein said automatically decomposing comprises: defining a target optimization function, wherein the target optimization function computes an estimated run time of the simulation model, wherein the target optimization function is based on a communication time within each co-simulation component and a communication time between each pair of co-simulation components; and determining a decomposition of the simulation model that optimizes a value of the target optimization function. The method further comprises executing the decomposed simulation model by executing in parallel each co-simulation component on a different simulation platform, whereby the simulation model is executed in a distributed manner.

Automatic decomposition of simulation model

A method, system, and product for simulation of Internet of Things (IoT) environment. The method performed by a simulation node in the IoT environment, which comprises the simulation node and a cloud server connected by a computerized network. The method comprises selecting a simulated IoT device to simulate from a plurality of simulated IoT devices that are being simulated by the simulation node; invoking a real-world model to obtain real-world simulated values; determining a simulated behavior of the selected simulated IoT device by invoking a device model and providing the real-world simulated values thereto, o wherein the simulated behavior comprises transmitting a message to the cloud server; setting a next simulated action of the simulation node to occur at a designated time, wherein the next simulated action is the simulated behavior; and performing the next simulated action at the designated time.

Simulation of internet of things environment

A computer-implemented method, computerized apparatus and computer program product for supporting parallel user interaction with physical and modeled system. A computerized digital model representing a real world physical system is obtained. An indication of a physical component of the system being subject to engagement by a user is received. A model component corresponding to the physical component is automatically determined. An interaction of the user with the model component is controlled based on at least one of the model and data obtained through engagement with the physical component.

Parallel user interaction with physical and modeled system

A method for concise modeling including receiving a first model mapping a plurality of prototype connections between a plurality of prototype objects, receiving at least one dataset having a plurality of optional objects, each object matching one of the prototype objects, and automatically constructing a second model having at least one of the optional objects mapped according to the first model.

Concise modeling and architecture optimization

A media-rendering apparatus for real-time streaming of audio/video (AV) data to a media-player having one or more input direct-access-storage-device (DASD) interfaces, the apparatus including a real-time AV data source unit, an input frame buffer operatively coupled with the real-time AV data unit, an AV real-time encoder, an encoded-frames buffer, a power source, a storage-device content emulator and a DASD interface device for communicating with the media-player. Preferably, power is provided through the DASD interface device.
