FindMinimumIndex

Playground for using SIMD for calculating the Index of the minimum in a array of floats.

If you have already google benchmark installed

git clone https://github.com/AnChristos/FindMinimumIndex.git

Also install google benchmark

Assuming you want also the google bench mark code

git clone --recursive https://github.com/AnChristos/FindMinimumIndex.git

cd findMinimumIndex/

The following will install the benchmark under ${HOME}/.local

source buildGoogleBenchmark.sh

edit

cmake -DCMAKE_BUILD_TYPE=Release -DBENCHMARK_ENABLE_GTEST_TESTS=OFF -DCMAKE_INSTALL_PREFIX=${HOME}/.local ../

to change location

Build with CMake

mkdir build; cd build

cmake ../FindMinimumIndex

make

./findMinimumIndex_bench --benchmark_report_aggregates_only=true --benchmark_repetitions=20
