Automatic Virtualization of Accelerators

AvA is a research system for virtualizing general API-controlled accelerators automatically, developed in SCEA lab at University of Texas at Austin. AvA is prototyped on KVM and QEMU, compromising compatibility with automation for classic API remoting systems, and introducing hypervisor interposition for resource management and strong isolation.

This repository is the main codebase of AvA. We host customized Linux kernel, QEMU, LLVM, and sets of benchmarks in separate repositories.

We are refactoring AvA code for better extensibility and developer-friendliness. The refactoring breaks a few functionalities at this moment, but they are coming back.

Setup code tree

git clone git@github.com:utcs-scea/ava.git

System requirements

AvA was fully tested on Ubuntu 18.04 (Linux 4.15) with GCC 7.5.0, Python 3.6.9, Boost 1.71.x, cmake 3.19.1 and Protobuf 3.0-3.9. The system also works in Ubuntu 16.04 with additional care of Python 3.6 and Clang-7 installation for CAvA scripts, but we do not maintain the support anymore. We plan to migrate AvA to Ubuntu 20.04.
