Hi Mike,
Is HPL a latency and/or bandwidth performance test? *All the
Analyze
plug-ins in lib/MTT/Test/Analyze/Performance are for latency/
bandwidth
tests, which means they can then be rendered as graphs in the
MTT
Reporter. *All of these plug-ins are required to output at
least one
of the following:
*latency_avg
*latency_min
*latency_max
*bandwidth_avg
*bandwidth_min
*bandwidth_max
They all contain this:
*$report->{test_type} = 'latency_bandwidth';
HPL.pm should have a line like this somewhere:
*$report->{test_type} = 'tv_gflops';
Maybe HPL.pm could go into a different directory or have a
comment
somewhere to clear up this confusion.
Regards,
Ethan
