CCBench : Redesign and Implement Many Concurrency Control

This platform is undergoing rewrite in the repository below.
https://github.com/thawk105/ccbench_v2
Analysis paper using CCBench is below.
http://www.vldb.org/pvldb/vol13/p3531-tanabe.pdf

Installing a binary distribution package

On Debian/Ubuntu Linux, execute below statement or bootstrap_apt.sh.

$ git clone --recurse-submodules this_repository
$ cd ccbench
$ sudo apt update -y && sudo apt-get install -y $(cat build_tools/ubuntu.deps)

Prepare using

note : Make install should be done by specifying a user-local path at the time of configure.

$ cd ccbench
$ "run some build_tools/(bootstrap*.sh) files"

• Processing of bootstrap.sh :
  Build third_party/masstree.
• Processing of bootstrap_mimalloc.sh :
  Build third_party/mimalloc.
  
• Processing of bootstrap_tbb.sh :
  Build third_party/tbb
  

Export LD_LIBRARY_PATH to appropriate paths.
Each protocols has own Makefile(or CMakeLists.txt), so you should build each.

Data Structure

Masstree

This is a submodule.
usage:
git submodule init
git submodule update
tanabe's wrapper is include/masstree_wrapper.hpp

Experimental data

Runtime arguments

This system uses third_party/gflags and third_party/glog.
So you can use without runtime arguments, then it executes with default args.
You can also use runtime arguments like below.
Note that args you don't set is used default args.

$ ./cicada.exe -tuple_num=1000000 -thread_num=224

Details for improving performance

• It uses xoroshiro128plus which is high performance random generator.
• It is friendly to Linux vertual memory system.
• It uses high performance memory allocator mimalloc/tbd appropriately.
• It reduces memory management cost by our original technique.
• It refrain from creating temporary objects to improve performance as much as possible.
• It fixed bug of original cicada.
• It modifies almost protocols appropriately to improve performance.
