Thanks for your reply. I think its the best to give you the versions of the implementations I use
OpenMPI 1.8.2 MPICH 3.0.2 LAM MPI 7.1.5 As you see in my program code, I use MPI_Win_get_attr to show the size of the window. Program crashes here. So I presume something went wrong at the WIN_Create call. I can comment out the MPI_Win_get_attr call, but then MPI_Get reads wrong data. I presume It reads somewhere outside the window because printf will show something like 2478000 Mit freundlichen Grüßen Florian Hahner -----Ursprüngliche Nachricht----- Von: users [mailto:users-boun...@open-mpi.org] Im Auftrag von Jeff Squyres (jsquyres) Gesendet: Dienstag, 17.

What version of Open MPI are you using? Be sure to use the latest to get the most correct one-sided implementation. Also, as one of the prior LAM/MPI developers, I must plead with you to stop using LAM/MPI. We abandoned it many years ago in favor of Open MPI. :-) On Jun 17, 2014, at 3:59 PM, Florian Hahner <h...@florian-hahner.de> wrote: > Hello MPI users, > > first of all i want to introduce myself.
