hello Neks.
I am a Nek5000 user and want to test nek5000 scalability,so I try to
rewirte the file.

I modify the makenek file:
==========================================
FFLAGS="-DTST_WSCAL"
CFLAGS=" "
==========================================

I added the statment in reader_par.f
==========================================
      param(151) = 30
      param(150) = 50
==========================================

so i try to run the demo ethier,but i got the error iformation like these:
==========================================
