Comment (by eschnett):

 You cannot compare performance between different MPI version with
 performance of the reference BLAS. We are talking about a factor of ten
 here. Compare it rather to a utility that chooses not to install an
 Infiniband driver since a Gigabit Ethernet driver is already present on
 the system.

 If you think that thorn OpenBLAS should use an installed, slow library
 instead of building an efficient OpenBLAS, then we disagree very much on
 what this thorn should be doing.
