IPF2: Towards Networked and Data-Centric Platforms

The IPF2 project focusses on expanding the factory concept of IPF1 towards multiple, networked and heterogeneous multicore processors. A very well known application would be a distributed ECU(electronic control unit) infrastructure found in modern automotive vehicles (see picture above). In such a distributed ECU, multiple multicore processors with different levels of heterogeniuity (e.g. CPUs, GPUs, FPGAs) are connected together using a high speed communication networks e.g. time sensitive networks (TSNs). In such automotive vehicle architectures, a large amount of data is being generated on the vehicle by the high quality, high data rate sensors (e.g. cameras, lidar, radar) and also the data generated by vehicular functions such as advanced driver assistance (ADAS) and highly autonomous driving (HAD) functions. To address the processing and transfer of such a large amount of data, we forsee the necessity to shift from a predominantly compute-centric in architecture development towards a holistic compute- and data-centric perspective. The IPF2 project with its new data-centric perspective will affect where and how data is stored, transferred and processed within a vehicle, as well as between different vehicles in the future (e.g. vehicle platooning).

 

Our work

Towards the goal of a data-centric perspective design of networked multi-core processors, our work at TUM addresses two major problems:

1. Developing configurable dynamic NUMA for faster memory access among network connected multi-core systems.

Modern vehicle architecture are made up of a few domain specific computers plus one or more high performance units for automated driving and sensor fusion. The compute units are connected together by a Time Sensitive Network (TSN) which is a real-time version of Ethernet. The sensors generate a lot of data which are fused by the sensor fusion entity and stored in a centralized location. The results can then be accessed over the network. This compute-centric approach although cost-efficient is not power and performance optimal. Factors such as access latency, network load  and power consumption strongly depend on the distance between the data i.e memory and the processing units. Dynamic-NUMA focusses on allowing the network-connected architectures to directly access the memory of the other networked nodes in a decentralized manner to improve performance.

2. Task and Data Migration Mechanisms using Learning Classifier Tables
In modern vehicles, data is generated from different locations and are processed. The execution time of the task processing the data is highly dependent on where the data is generated and stored. The performance of the task can be improved by either moving the data closer to the task or vice versa. In this work, we track different metrics such as number of memory accesses to local node and networked node, execution time, power consumption of the processing node and use them in conjunction with our Learning Classifier Tables, to learn a policy in runtime to either migrate the task or the data in the networked architecture.
