there is no such thing as a "parallel version" of ld1.x : it always runs
on a single processor. It can be compiled and run in the same way
as all other codes for the user's convenience.

there must be something wrong with input redirection.
"mpirun -np 2 /path/ld1.x < h.in > h.out" works. In any case,
don't run it in parallel: you gain nothing
