Dear Prof. Troyer,

ALPS could be successfully configured and installed.

However, I'm still unable to run parallel codes because of some issue with linking mpi and ALPS.
I get the following error:
mpirun -np 10 dmrg --mpi --Nmax 1 parm_0hx.in.xml --write-xml
mpirun: error while loading shared libraries: libopen-rte.so.7: cannot open shared object file: No such file or directory

While configuring and installing, I had set the following cmake variables ON:
ALPS_BUILD_FORTRAN
ALPS_ENABLE_MPI
ALPS_ENABLE_OPENMP
ALPS_ENABLE_OPENMP_WORKER

I've been referring to the following link to resolve the issue, but haven't been successful yet: https://www.open-mpi.org/faq/?category=running#adding-ompi-to-path

Thanks again.

Regards,
Pradeep.

You need to tell make where you installed MPI
