Efficient Remote Memory Ordering

Code for submission to ASPLOS 2026.

gem5 Simulation

The files for gem5 simulation can be found in the gem5 directory. The files are obtained from version 24.1 of gem5.

Requirements for gem5:

• gcc version >= 10
• Clang 7 to 16
• SCons 3.0 or greater
• Python 3.6+
• protobuf 2.1+

Python requirements for plotting results:

• NumPy
• Matplotlib

Scripts for running the gem5 simulations can be found in the directory gem5-scripts.

Instructions for reproducing the figures from gem5 simulation:

1. Enter the gem5 script directory: cd gem5-scripts
2. Run the script to set up and build gem5: ./setup-gem5.bash
3. Run the script to run all simulations: ./run-gem5.bash
4. Set the python command in line 3 of plot-gem5.bash (default is python3)
5. Run the script to plot all simulation results: ./plot-gem5.bash

Plots can be found in the directory gem5-scripts/plots.

CACTI

Scripts for building and running CACTI can be found in the directory cacti-scripts.

Instructions for obtaining the CACTI results:

1. git submodule init
2. git submodule update
3. Enter the CACTI script directory: cd gem5-scripts
4. Build CACTI: ./build_cacti.bash
5. Run CACTI: ./run_cacti.bash

Results can be found in the directory cacti-scripts/results.
