My CPU type is Intel Atom (Silvermont) processor.īut the values are constant. I think I activated likwid-bench and it accepts also stream_avx because I get the following output: Is there anything else to do besides above to activate MarkerAPI? I set to true FORTRAN_INTERFACE and INSTRUMENT_BENCH in config.mk, t hen I used: (The -m switch on the command line activates the MarkerAPI, some simple code instrumentation calls, but you have to activate the support for the MarkerAPI for likwid-bench in config.mk before compilation)ĭoes likwid-powermeter print anything at all? If you used the standard make & sudo make install way, you should be able to run it as user: Are you using a package provided by your distribution or built it yourself?
The first Intel CPU supporting AVX and power readings is Intel SandyBridge.Ĭommonly, you don't need to run LIKWID with sudo. With this information it is easy to say whether your system supports AVX and power readings. CPU name: Intel(R) Core(TM) i7-4770 CPU 3.40GHz Which CPU architecture is it? If you don't know, try likwid-topology and look at the header. Illegal instruction sounds as your architecture is not supporting AVX (try stream instead of stream_avx).
