it shouldn't make any difference: lapack routines should be linked from essl if present there, from /gpfs/usrurz/lib64 if not. Nothing should be linked from the internal library. The best way to be sure is "experimental computer science", i.e., to try and see what happens. P. --- Paolo Giannozzi, Dept of Chemistry&Physics&Environment, Univ.
