threadpool_benchmark

Benchmark of some thread pool implementations in C++.

The following implementations are benchmarked, against parallelized prime number search:

• Single threaded baseline
• https://github.com/vit-vit/CTPL
• https://github.com/henkel/threadpool (also from here: http://threadpool.sourceforge.net/index.html)
• https://github.com/progschj/ThreadPool
• http://www.boost.org/doc/libs/1_62_0/doc/html/thread/synchronization.html#thread.synchronization.executors (no need to clone, but exists only from boost 1.56 and up)
• thread_pool.hpp using boos::thread_group and asio. Based on: http://stackoverflow.com/questions/12215395/thread-pool-using-boost-asio code from Tanner Sansbury (no need to clone as code is copied into this project)

To build use make

To run: ./benchmark_pool <size of input> <number of procs>

To fetch all implementations needed for the benchmark, call ./fetch_dependencies.sh. Benchmarked implementations will be cloned under a lib directory.

To run multiple times for different different number of threads (up to max procs) use: ./run_benchmark.sh <interation> <max processors>

To build and run against CentOS7 and FreeBSD11, run vagrant up under the centos and freebsd directories. Information about Vagrant is here: https://www.vagrantup.com/
