The configure flag "--enable-shared-memory-only" triggers a build of ELPA without MPI support: - all MPI calls are skipped (or overloaded) - all calls to scalapack functions are replaced by the corresponding lapack calls - all calls to blacs are skipped Using ELPA without MPI gives the same results as using ELPA with 1 MPI task! This version is not yet optimized for performance, here and there some unecessary copies are done. Ths version is intended for users, who do not have MPI in their application but still would like to use ELPA on one compute node
