Technology Overview

EXTOLL introduces a new interconnection network architecture for High-Performance Computing, which brings a rich set of features to the HPC application space. The main characteristics of EXTOLL technology include:

• Ultra low latency message exchange
• Extremely high hardware message rate
• Low memory footprint
• Switchless Design
  - 3D Torus Direct Network
• High scalability
• Single chip solution
• Extremely efficient, pipelined hardware

The block diagram to the right shows an implementation of EXTOLL with its highly modular architecture.


The EXTOLL solution integrates host-interface, network interface controller and network functions within a single chip. This single chip solution enables power efficiency and lower total cost of ownership.
