I just want to mention that, in Wien2k 12.1, SRC_lapw0 contains include files from fftw3 such as fftw3.f03 and fftw3-mpi.f03. I believe these are from version 3.3.2. For version 3.3.3 (or a future version), the include files have changed. Perhaps this might cause a problem on "only some" systems if the 3.3.3 library is used with the 3.3.2 include files.
Option 1: Try copying the include files from 3.3.3 into SRC_lapw0 to replace the 3.3.2 files Option 2: Try renaming, moving, or deleting all the 3.3.2 include files in SRC_lapw0 and add the library path to the location of the include files in the compile settings Prof. Blaha, perhaps this might explain the problem you mentioned having with parallel fftw3. -------------- next part -------------- An HTML attachment was scrubbed...
