Which SPEC MPI2007 metric should be used to compare performance?
A base measurement is required in every reportable run. The corresponding peak measurement is optional but is useful to show how high performance your system can achieve. When the larger lref and xref data sets become available, you will have to decide which to use. The larger data sets will scale to larger machines and so give a more accurate picture of the performance on large problems. On the other hand, more results will have been reported with the mref data set size, so it will provide a more common reference point of comparison.
