[Nek5000-users] problems in compiling the code for parallel run

Hi Mansi,

I suspect that you can safely ignore the error.  The error probably comes
from line 7 of the "nekbmpi" script:
mv $1.sch $1.sch1
This command is intended to move the .sch file from a previous run, in case
there's one in your directory. If this is your first run, there will be no
.sch file in your directory, and the "mv" command will give the error you
saw. So it probably doesn't indicate a problem.

Best,
