Re: [PerfSuite-users] profiling communication

[George M. <ge...@ma...>]

Dear all,

thanks for your answers, I was wondering mainly for profiling only with 
this tool both hardware counters and MPI communication but ok you 
answered my question, I was just confused by the documentation.

Thanks a lot,
Best regards,
George
