Experiment workflow

Section VI-A, B, C, E needs docker.

For VI-A, B, C, we provide a docker image chenlumiao/unxpec:01.To run Docker, enter unXpec directory, run

bash run.sh docker

For VI-E, we provide another docker image chenlumiao/unxpecspec:01. We don’t provide a shell script, you can mount a directory on our docker image to run your spec2017 benchmarks.

To run Docker, enter unXpec directory, run

Section VI-A: Timing Difference.

In the given docker environment

cd /home/gem5/unXpec

• To run codes without eviction sets, run

bash run.sh TimingDifference

results are unXpec/TimingDifference/NoEvictionSet_Sec0.txt and unXpec/TimingDifference/NoEvictionSet_Sec1.txt

• To run codes with eviction sets, run

bash run.sh TimingDifference -e

results are unXpec/TimingDifference/EvictionSet_Sec0.txt and unXpec/TimingDifference/EvictionSet_Sec1.txt

Section VI-B: Leakage Rate

In the given docker environment

cd /home/gem5/unXpec

To run codes, use

bash run.sh LeakageRate

Results will be printed on the console.

Section VI-C: Secret Leakage

In the given docker environment

cd /home/gem5/unXpec

• To run codes without eviction sets, run

bash run.sh SecretLeakage

result is unXpec/SecretLeakage/NoEvictionSet_Sample1k.txt

• To run codes with eviction sets, run

bash run.sh SecretLeakage -e

result is unXpec/SecretLeakage/EvictionSet_Sample1k.txt

Section VI-D: Noise Insensitivity

The code should be run on a real machine with ubuntu operating system.

bash run.sh NoiseInsensitivity

result is unXpec/NoiseInsensitivity/result.txt

Section VI-E: Mitigation: Constant-time Rollback

We provide a new docker image chenlumiao/unxpecspec:01. We don’t provide a shell script to create a docker container, you can mount a directory on our docker image to run your spec2017 benchmarks.

Put all benchmark files including their executable files and input files into a directory (addressed as spec_dir subsequently).

Copy all files in spec_dir to the docker container created by "unxpecspec:01" with following commands:

• use docker ps to get the container ID (addressed as ContainerID subsequently)

• use docker cp spec_dir/. ContainerID:/home/gem5 to copy all files in spec_dir to the docker container

In the new docker container

cd /home/gem5

bash run_gem5spec.sh benchmark_name maxinst_count startinst_count scheme_cleanupcache

such as

bash run_gem5spec.sh exchange2_r 2000000000 1000000000 Cleanup_FOR_L1L2

results see /home/gem5/test##benchmark_name

such as /home/gem5/testexchange2_r
