 ranger-intel11.cfg now sets BLAS and LAPACK to be built along with the
 Cactus and other external libraries. Usually the host system BLAS and
 LAPACK are fine tuned to
 take advantage of the particular memory hierarchy of the host machine. I
 was wondering if this fine tuning is performed when we set BLAS = BUILD or
 LAPACK = BUILD, and, in case it is not, if it would be interesting to
 define Cactus env variables to set the size of the several cache memories
 for example and use it for this necessary fine tuning.
