StripeMerge

This repository includes source code of StripeMerge prototype system described in our paper accepted by ICDCS'21.

Preparation

We implement StripeMerge on Ubuntu-16.04. So the tutorial as follows is also based on Ubuntu-16.04.

Users can use apt to install the required libraries.

• g++
• make & cmake
• nasm
• libtool & autoconf
• git

$  sudo apt install g++ make cmake nasm autoconf libtool git

StripeMerge is built on ISA-L and Sockpp. Users can install these two libraries manually:

• Intel®-storage-acceleration-library (ISA-L).

  $  git clone https://github.com/intel/isa-l.git
  $  cd isa-l
  $  ./autogen.sh
  $  ./configure; make; sudo make install

• Sockpp

  $  git clone https://github.com/fpagliughi/sockpp.git
  $  cd sockpp
  $  mkdir build ; cd build
  $  cmake ..
  $  make
  $  sudo make install
  $  sudo ldconfig

Installation

• Users can install StripeMerge via make.

  $  cd stripe-merge
  $  make all

Configuration

• Before running, users should prepare the configure. The example configure are presented in config/nodes_config.ini, where the first line is RS code parameters k and m, followed by the IPs and ports of helper_nodes in need.

• Or you can also generate the config/nodes_config.ini using script util/cloud_exp.py, by passing RS code parameter k, m as well as the number of helper_nodes that actually runs. Port in default is 15000. Note that before generating, config/nodes_ip.txt should be filled with IPs of all helper_nodes .

  $  python3 util/cloud_exp.py get_config  k  m  nodes_num

• Users can use script util/cloud_exp.py to update the configure or program in helper_nodes either. (To utilize this tool, user should configure that the master_node connect to all helper_nodes by SSH without password. Note that the script is based on the assumption that the helper_nodes are mapped orderly like node01/node02/.../node32 in /etc/hosts. Users should also provide user_name and dir_base at the beginning of the script.)

  $  python3 util/cloud_exp.py update [all/config/program] nodes_num

• Use dd to generate a random block in all helper_nodes to test.

  $  dd if=/dev/urandom of=test/stdfile bs=1M count=64

Run it

• To run the prototype system, users should run the master_node (at the root directory of repository),

  $  cd stripe-merge
  $  ./build/bin/node_main 0 stripes_size [exp_type: 0-p, 1-g, 2-ncs]

  and run the helper_nodes respectively (at the root directory of repository, too).

  $  cd stripe-merge
  $  ./build/bin/node_main [1/2/3/...]

  Or Users can use the script on master_node to conduct the experiment. (Same requirement as above mentioned.)

  $  python3 util/cloud_exp.py exp  stripes_size  k  m  nodes_num  [0-p, 1-g, 2-ncs]

• You can also run the matching simulator locally with the parameter you want, to compare StripeMerge-P withStripeMerge-G .

  $  ./build/bin/matching_main [stripes_num] [host_num] [rs_k] [rs_m]
