SpMV evaluation

Anthon Porath Gretter - 259030

Building

Before building, make sure you have CUDA/11.8.0 installed and loaded. To build the desired implementation you can simply type

make spmv_<implementation name>

Where <implementation name> can be cpu_csr, gpu_mem, gpu_unrl or gpu_dyn. Or even, to build all CPU or/and all GPU implementations¹ just run:

make cpu
make gpu

You can always add additional jobs to make, like -j8, to enhance compilation time.

Usage

To run, provide a valid .mtx file alongside the desired implementation call. There are some .mtx included in the resources directory². Below sits an example:

./spmv_gpu_mem ./resources/rim.mtx

[1] the implementations are compiled separately due to the usage of Compile-time Conditional Inclusion. So if make does not do that automatically, please make sure there are no object files from previous compilations.
[2] All available matrix market files were gathered from https://sparse.tamu.edu/
