UXU: Ultimate eXtensible UVM

UXU is a multi-level swapping for GPGPU memory, which is inspired from DRAGON. Using UXU, large-scale GPGPU applications exceeding GPGPU physical memory can be easily executed.

Getting Started

This project composes of multiple components. To install DRAGON, follow the instructions in the INSTALL.md file. To compile or run provided example applications, see the README.md file in the examples folder.

Install UXU kernel driver

UXU kernel driver is a kind of modified NVidia UVM(Unified Virtual Memory) in the same way by DRAGON. NVidia 440.82 kernel source is used as a codebase for our driver. Below installation procedure assumes Ubuntu 18.04.

1. Prepare linux kernel build environment Most 4.15.x would be fine. One of tested versions is 4.15.0.140

2. Build kernel modules

   # cd kernel_nvidia
   # make -C /lib/modules/4.15.0-140-generic/build M=$PWD
   

   After successful build, several kernel modules will be generated. Two modules nvidia.ko and nvidia-uvm.ko are required to run UXU.

Install libuxu library and examples

User-land library and examples can built with autotools.

# ./configure
# make
