Why aren performance metrics generated for the test and train data sets?
The mtest, ltest, mtrain and ltrain data sets are provided for the purpose of validating the correctness of the compile and the run environment. Running with these data sets will give you a report that includes the run time, but no performance metric is derived because these input sets are not intended for performance measurement. The MPI2007 source directories include reference run times for these data sets; these have to be included because of the way the report-generation tools are built.
