Instructions

IMPORTANT

There are predefined devices in the fio configuration files. PLEASE REPLACE THEM WITH YOUR OWN DEVICE.

Environment

Install fio

git clone https://github.com/axboe/fio.git
git checkout 77c758db876d93022e8f2bb4fd4c1acbbf7e76ac
cd fio
./configure
make

NOTE: Please add fio to $PATH

Install SPDK

SPDK setup fio spdk setup manual

git clone https://github.com/spdk/spdk.git
cd spdk
git checkout aed4ece93c659195d4b56399a181f41e00a7a25e
git submodule update --init
sudo scripts/pkgdep.sh

# Configure with fio
./configure --with-fio=/path/to/fio/repo <other configuration options>

make

# bind and unbind device

sudo scripts/setup.sh

sudo scripts/setup.sh reset

Make sure there are huge pages on the node where SPDK will be run on. For example:

sudo HUGENODE="nodes_hp[0]=4096,nodes_hp[1]=4096" $SPDK/scripts/setup.sh

Prepare

Fully write the devices 10 times before the experiment

cd write_device
sudo ./run.sh

NOTE

  • Set the 'SPDK_FIO_PLUGIN' and 'SPDK_SETUP_PATH' before run the script
  • Fill your own devices in the fio configurations file before running.
  • In fig 7 and fig 8, the script will automatically turn down the CPU 0 using chcpu. Replace it with your cpu id in socket 1, or delete them if there is only one NUMA node on your machine.

Figure 2

Before running the script:

  • Set the 'SPDK_SETUP_PATH' environment variable.
  • Disable the CPU core that are not in the same socket with the device

Run the script and plot:

cd 2-iops_d1_qd_1
mkdir results
sudo ./run.sh
python3 plot.py

Figure 3

  • Set the 'SPDK_SETUP_PATH' environment variable.
  • Disable the CPU core that are not in the same socket with the device

Run the script and plot:

cd 2-iops_d1_qd_1
mkdir fio perf_graph perf_list perf_output
sudo ./run.sh
python3 plot.py

NOTE:

The work breakdown of iou-s might not be parsed correctly by the script. The work breakdown needs to be calculated manually for the perf report.

For spdk

  • Parse the perf file with srcline(set your vmlinux path):
perf report --vmlinux $VMLINUX -n -m --stdio --full-source-path --source -s symbol,srcline -i perf_output/spdk_fio.perf.out >> spdk_srcline.txt;
  • Delete all the lines that does not contain the actual data
  • Get the number of instructions and instructions taken by SPDK
# all
cat spdk_srcline.txt | tr -s ' ' | cut -d ' ' -f 3 | awk '{ sum += $1 } END { print sum }'
# spdk
grep $YOUR_SPDK_PATH spdk_srcline.txt | tr -s ' ' | cut -d ' ' -f 3 | awk '{ sum += $1 } END { print sum }'
  • fill the overhead of spdk and fio in plot.py:112

Figure 4

Before running the script:

  • Set up the 'SPDK_FIO_PLUGIN', 'SPDK_SETUP_PATH'
  • Disable the CPU core that are not in the same socket with the device

Run the script and plot:

cd 4-micro_arch_qd1
mkdir results_global results_local
sudo ./run.sh
python3 plot.py

Figure 5-a-b

Before running the script:

  • Set the 'SPDK_SETUP_PATH' and 'SPDK_FIO_PLUGIN' environment variable.
  • Disable the CPU core that are not in the same socket with the device

Run the script and plot:

sudo ./run.sh
mkdir results
python3 plot.py

Figure 5-c

see figure 3

Figure 6

see figure 4

Figure 7

Before running the script:

  • Set the 'SPDK_SETUP_PATH', 'SPDK_FIO_PLUGIN' environment variable.

Run the script and plot:

cd 7-multi_thread
sudo ./run.sh
mkdir results
python3 plot.py

Figure 8

Before running the script:

  • Set the 'SPDK_SETUP_PATH' environment variable.

Run the script and plot:

cd 8-scheduler_multi_thread
mkdir results
sudo ./run.sh
python3 plot.py
