A paper on I/O simulation in SimGrid.

Generate the pdf from svg figures

Generate pdf files used in the paper from svg files.

1. Install inkscape
2. ./generate_figures.sh

Generate the figures

If the svg files are not available to generate pdf files, you should re-generate the svg files from experiment results by running the python script gen_fig.py.

Experimental figures are generated and saved in:

• Single-threaded experiment: result/single/figures/
• Multi-threaded experiment: result/multi/figures/

The other general figures can be found here

Get the log files

If the log files are missing, or if you would like to run the experiments with your own configurations, you should run the real pipeline/simulators to generate these logs.

1. Real execution

1.1 Single-threaded experiment.

• Log files location: result/single/real/.

1.2 Multi-threaded experiment.

• Log files location: result/multi/local/real/.

1.3 NFS experiment.

• Log files location: result/multi/nfs/real/.

If the log files are not available, or you want to generate your log files from your own experiment, run pipeline on a real system using the source code in exp/real/

2. Single-threaded simulation

2.1 Python simulator

• Log files location: result/single/pysim/.
• How to run: use the source code in /exp/pysim/, follow the instructions in README.

2.2 Original WRENCH simulator

• Log files location:
  • Original WRENCH: result/single/wrench/original/
  • WRENCH-cache: result/single/wrench/pagecache/
• How to run: use this source code example, follow the instructions in README.

3. Multi-threaded simulation

• Log files location:
  • Original WRENCH: result/multi/local/wrench/original/
  • WRENCH-cache: result/multi/local/wrench/pagecache/
• How to run: use the source code example, follow the instructions in README.

4. NFS simulation

• Log files location:
  • Original WRENCH: result/multi/nfs/wrench/original/
  • WRENCH-cache: result/multi/nfs/wrench/pagecache/
• How to run: use the source code example, follow the instructions in README.
