In this presentation, I address the difficult problem inherent in SKA
of deploying complex astronomical applications under development on
efficient target architectures that have not yet been built. Resource
allocation in such scenarios has a significant impact on multiple
factors such as latency, memory, energy, and cost among
others. Solutions such as rapid prototyping make it possible to
reliably simulate and generate efficient code for this purpose. At
INSA-IETR, we are developing the PREESM rapid prototyping tool to
automate and accelerate this process. The tool is based on numerous
thesis and internship projects as well as numerous collaborations such
as Rising Stars, which is the subject of my presentation. This
presentation will give an overview of the project's progress in our
team. I propose methods based on the SDF (Synchronous Dataflow) model
and clustering techniques to facilitate the deployment of applications
on complex architectures such as CPUs, GPUs, and FPGAs on one or more
machines. By providing a quick and easy solution to this NP-hard
problem, our methods significantly improve the efficiency of
astronomical application deployment.
As tomorrow is the ANZAC Day national holiday in Australia, the next ADAP will be Friday April 26th. |
