Optimus: A Hypervisor for Shared-Memory FPGA Platforms

All of the source code for Optimus is open source, and is comprised of the following components:

Optimus Hypervisor

• https://github.com/efeslab/optimus-host-module
• The Optimus Hypervisor is provided as a host kernel module.

Hardware Monitor

• https://github.com/efeslab/optimus-intel-fpga-bbb/tree/master/BBB_vai_mux_nested/hw
• The hardware monitor is provided as a basic building block (BBB).

Guest Driver

• https://github.com/efeslab/optimus-guest-driver
• The guest driver is provided as a guest kernel module, which drives the virtualized accelerator.

Guest Core Library

• https://github.com/efeslab/optimus-opae-sdk
• The guest core library is embedded in the Intel OPAE SDK.

Guest MPF Library

• https://github.com/efeslab/optimus-intel-fpga-bbb/tree/master/BBB_cci_mpf/sw
• MPF is a software/hardware library which provides a group of memory properties such as memory ordering. We have modified the library to support virtual accelerators.

Benchmarks

• MemBench, LinkedList, SSSP, and Bitcoin can be found in https://github.com/efeslab/optimus-intel-fpga-bbb/tree/master/samples/tutorial. We additionally include our ports of three benchmarks from HardCloud (grayscale, sobel, and gaussian) in this repository, as these benchmarks required significant changes to run on our platform.
• The hardware portion of the remaining HardCloud benchmarks can be found in https://github.com/efeslab/hardcloud. The software portion of these benchmarks can be found in https://github.com/efeslab/hardcloud_no_openmp. Note that the benchmarks are compiled without OpenMP support.
• The synthesis configuration for these benchmarks can be found in https://github.com/efeslab/optimus-intel-fpga-bbb/tree/master/samples/tutorial/synth_config.

Setup Guide

• Our code is developed and tested using the hardware and software specificed here.
• A step-by-step tutorial is available here to help you build everything from scratch.
• Some scripts we used in our experiment can be found here.
• The definition of Optimus's preemption interface can be found here.
• A brief guide for pass-through setup can be found here.
