MOPS

Build

Build flags:

• WITH_OPENMP Compile with OpenMP support for parallel execution
• WITH_TACO Use TACOs write function to store the generated matrix
• WITH_LIKWID Compile with LIKIWID support to profile performance of the compute kernel

The following demonstrates how to compile MOPS with OpenMP and LIKWID support.

$ mkdir build && cd build
$ cmake -DCMAKE_BUILD_TYPE=Release -DWITH_OPENMP=yes -DWITH_LIKWID=yes .."
$ make

Matrix Generation

$ ./mops --generator --g_read [PATH] --g_write [PATH] --cols [cols] --rows [rows] [--copy] [--tacoed]

LIKWID Profiling

In order to generate performance counter backed data, run the MOPS computation with thread pinning and likwid-perfctr

$ likwid-perfctr -C N -g MEM_DP -m  ./mops -i ./dense_matrix_1000x1000.mtx -o ./1000x1000.mtx -t 32
