EXTOLL - The Interconnect Component for Dense Supercomputing

SESSION: Hardware and Architecture

EVENT TYPE: Exhibitor Forums

TIME: 2:30PM - 3:00PM

SESSION CHAIR: Carlos Rosales

Presenter(s):Ulrich Bruening



EXTOLL is a high-performance interconnection network targeted for dense supercomputing. EXTOLL’s unique feature of a PCIe root-complex allows for autonomous boot and operation of accelerators without a direct connected host.
Combining an accelerator like the Xeon Phi and the EXTOLL NIC into a node builds a very dense compute node which is called Booster. This host-less Booster concept was developed in the EU-Project DEEP. Aggregating such nodes in a 3-D torus topology allows building very dense compute cabinets. Now power density becomes an issue, which is solved at the cabinet level by a 2-phase immersion cooling. More than 10kWatt of power dissipation can be removed from the 32 Booster nodes providing high performance of 32 TFLOPS at a yet unachieved density.
