1 month ago Hi, this is related to several reasons:
- No permission to collect: enable collecting in kernel settings or run the tool with sudo.
The current PMU metrics and the
jeventlibrary do not work on your setup. PMU collection is dependent on both the CPU arch and the OS kernel. Check pmu-tools for more information. You can try to
- collect only one metric to see if it works
- check the error code of underlying syscalls
I've tried a lot but it doesn't work.
I tried to run the tool with sudo. NPB can work successfully but VAPRO didn't generate anything.

npb@nas.nasa.govI've tried to collect only one metric like cpu/instructions/ or cycles (I modified in perf_jevent.cpp and pmc_jevent.cpp. If it's false please tell me). However it still did not work and still the same error message.

I don't know if there's a problem with my PAPI installation. When I ran the command papi_avail, 0 are available.

Thank you very much.
Hello, I'm trying to test with VAPRO. After I built all the dependencies and VAPRO, I'd like to use it to do some testing with NAS Parallel Benchmarks. However, when I run the command, there are some problems and I don't know how solve it.
The command and errors are displayed as follows:
The versions of the relevant tools are as follows:
Thanks for your help.
