I looked through the code and suspect Siesta is at fault but since they rolled their own MPI F90 wrappers and I know very little about F90, I cannot debug it. You will see that there are no wrappers for send, recv, bcast or reduce (the functions for which you get errors) in ./Src/MPI/mpi.F. There are references to these in ./Src/MPI/mpi__*.f90 but I don't understand what's going on very well. It also appears that these files are from a prototype implementation of the F90 module for MPI 1.1 written in 1996. I don't know if that was before the MPI standard defined F90 bindings, but it surely does now and applications should use those instead. The other thing you can do is turn off MPI in the utility code since it might not be necessary there. Jeff On Mon, Jul 8, 2013 at 11:09 AM, Hana Milani <[email protected]> wrote:

This doesn't look like an MPI error. Did you contact the authors of whatever package you are trying to compile?

Hello,

I have compiled a code (siesta) by mpich2, blacs, lapack, blas and scalapack. It works fine under grid computation. But when I want to "make" a utility, I receive the following errors:

I will be really grateful if you kindly help me to solve this problem.
