STL Benchmark

STL benchmark comparing C++ and Julia ⏱

For more information: STL Benchmark Comparison: C++ vs. Julia.

Getting Started

git clone --recurse-submodules [e-mail]:pddshk/stl-benchmark.git

NB! to run this you need to place #include <limits> into cpp/benchmark/src/benchmark_register.h

From the cpp directory:

export CC=/usr/bin/clang
export CXX=/usr/bin/clang++
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j
./stl_benchmark

Sample output

Running ./stl_benchmark
