Sparse matrix transposition: Datastructure performance comparison
Supplements blog post by Karl Rupp: https://www.karlrupp.net/2016/02/sparse-matrix-transposition-datastructure-performance-comparison
Build
Assuming that Boost is installed on the system, issue e.g. $> g++ main.cpp nothing.cpp -I. -O3 -DNDEBUG -o transpose
To build using CMake:
mkdir build
cd build
cmake ..then
make transpose
to build the executable, or
make benchmark
to build and run
Run
To run with a certain matrix size (e.g. 1000) and nonzeros per row (e.g. 10), pass them as parameters: $> ./transpose 1000 10
Plot
Have a look at the results/ folder, where the data and gnuplot commands are located. Replot via $> gnuplot plot.gnuplot (produces postscript plots)
Convert to .pdf via $> epstopdf FILENAME.eps and to .png using ImageMagick, e.g. $> convert -density 300 FILENAME.eps -resize 1150x FILENAME.png
