T2/x86 FSC Heterogeneous Cluster (veritates@kraftwerk)

Veritates Cluster Primary Processor Complex

Includes Primary User Interface/System Element (in the IBM sense) components. A work in progress, incomplete - in general, ask on the discussion page.

Primary Purpose

Primary Purpose: (Heterogeneous Distributed OS Development)/(Data Processing)/(Firmware Integration and Development) and "General Purpose" Workstation System - Once mature to provide full-control/debugging environment for low-level systems testing and verification including hardware/bus interposers (digital/analogue capture) for qualified local/remote users. Numerical Analysis and Software Build Services for OpenPOWER Compatibility/Performance Related Open Source Projects.

cycle/bus/transaction accurate simulation of the (POWER9/T2 SoC IPL) for FW development/verification

Design, Implementation and Verification of a cycle/bus accurate simulation of the POWER9/T2 IPL for use in systems firmware development and verification. I haven't been able to find an existing method for fully simulating systems firmware deployment and execution not involving actual hardware and support infrastructure. Ideally, physical hardware would be used only for model verification. More research on exist methods of development required.

formally verified re-implementation of OpenPOWER equivalent P9 SoC firmware

Formal verification of low-level systems firmware is vital for stability, security and algorithm correctness. Do so via re-implementation of OpenPOWER provided firmware equivalent POWER9 SoC firmware specifications/build systems using Ivory/Tower eDSL Models enhanced with LiquidHaskell refinement type system. Use Simulation to validate equivalent initialisation and run-time behaviour versus OpenPOWER provided firmwares.
