ConTutto is an IBM Research Configurable Platform for Innovation in the Memory Subsystem of an OpenPOWER Node

Abstract

ConTutto is an IBM Research configurable platform for innovation in the memory subsystem of an OpenPOWER node. By replacing the ASIC memory buffer chip of a commercial OpenPOWER server with a high-end FPGA connected to the processor’s memory link, we demonstrate the highest bandwidth attach point of an FPGA with a commercial server processor. Furthermore, we enable system-level innovations at multiple levels, including 1) Systems Research with new memory technologies, such as MRAM and NVDIMMs, and 2) Near-memory acceleration of data flowing between processor and memory. In this talk, we will present details of the ConTutto platform, and show various system-level demos using ConTutto in an OpenPOWER system. This work is partially funded through the Department of Energy FastForward-2 Government contract.
