Likwid is a simple to install and use toolsuite of command line applications and a library for performance oriented programmers. It works for Intel, AMD, ARMv8 and POWER9 processors on the Linux operating system. There is additional support for Nvidia and AMD GPUs. There is support for ARMv7 and POWER8/9 but there is currently no test machine in our hands to test them properly.
GliBench SMP is an SMP enabled benchmark for testing you computers performance. It is a rewrite of my tool CliBench which is quite known in the Windows world. It is based on GTK/Gnome which should make it simple to port to other OS.
