Test Environment Preparation

Software

First please make sure you are using our kernel.

You need to download following code and compile yourself, mostly they are written in c/c++ and go. Go version has to >= 1.20.

• faasd:

  • on switch branch: make local && make install

• faas-cli:

  • make local-install

• criu:

  • on switch branch: make -j32 install-criu && cp criu/criu /root/downloads/switch-criu

  • on v3.18: make -j32 install-criu && cp criu/criu /root/downloads/raw-criu

• containerd

  • on switch branch: BUILDTAGS=no_btrfs make && make install

• runc

  • on switch branch: make runc && make install

• faasd-testdriver

  • copy this dir to /root/test/

• rdma-server

  • make && cp pseudo-mm-rdma-server /root/test

Scripts

Three scripts in util repo is needed to run test:

• test.sh

  • used to run different test, e.g., azure trace test or functional test

• test-common.sh

  • define some common shell functions

• machine-prepare.sh

  • need to run only once for each system boot

However, machine-prepare.sh only start necessary daemon, insert kernel modules, configure softroce (rxe), generate checkpoints and mm-template (called pseudo_mm in kernel code). It will not install or compile software. So you need to compile software at first and put it in the right place.

After boot, run:

• bash machine-prepare.sh --mem-pool rdma --nic eth0 for rdma based test

• bash machine-prepare.sh --mem-pool dax --dax-dev /dev/dax0.0 for cxl based test

Then start test, run:

• bash test.sh --mem 64 for our method

• base test.sh --mem 64 --gc 10 --baseline for containerd / docker container

• base test.sh --mem 64 --gc 10 --baseline --start-method criu for starting container with CRIU
