In networked signal processing systems, network nodes that perform embedded processing on sensory inputs and other data interact across wired or wireless communication networks. In such applications, the processing on individual network nodes can be described in terms of dataflow graphs. However, to analyze the correctness and performance of these applications, designers must understand the interactions across these individual "node-level" dataflow graphs – as they communicate across the network – in addition to the characteristics of the individual graphs. In this paper, we develop a new simulation environment, called the NS-2 – TDIF SIMulation environment (NT-SIM) – that provides integrated co-simulation of networked signal processing systems. NT-SIM systematically combines the network analysis capabilities provided by the Network Simulator (ns) with the scheduling capabilities of a dataflow-based framework, thereby providing novel features for more comprehensive simulation of networked signal processing systems. Through a novel integration of tools for network and dataflow graph simulation, our NT-SIM environment allows comprehensive simulation and analysis of networked signal processing systems. We present a case study that concretely demonstrates the utility of NT-SIM in the context of a heterogeneous signal processing system design.

Free GPU computing nodes at hgpu.org

Registered users can now run their OpenCL application at hgpu.org. We provide 1 minute of computer time per each run on two nodes with two AMD and one nVidia graphics processing units, correspondingly. There are no restrictions on the number of starts.

The platforms are

Node 1
  • GPU device 0: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • GPU device 1: AMD/ATI Radeon HD 6970 2GB, 880MHz
  • CPU: AMD Phenom II X6 @ 2.8GHz 1055T
  • RAM: 12GB
  • OS: OpenSUSE 13.1
  • SDK: nVidia CUDA Toolkit 6.5.14, AMD APP SDK 3.0
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.3
  • SDK: AMD APP SDK 3.0

Completed OpenCL project should be uploaded via User dashboard (see instructions and example there), compilation and execution terminal output logs will be provided to the user.
