Re: [ESPResSo] MPI issue

[Kai Grass]

Hi,

I can't really comment on your problem, but I can tell you, that I  
compiled Espresso using OpenMPI (Version 1.2.3) on Mac (Intel Dual  
Core) and on a Sunfire Cluster. Both versions work fine, so in  
principle it should also work for you.

> mpirun -np 4 ~/Espresso/obj-XXX/Espresso_bin my_script.tcl

That is the correct call (which in fact is also issued by the  
Espresso wrapper).

To analyze your problem, it would help to have the config.log from  
Espresso. It looks like it didn't find the MPI libraries at compile  
time and resorted to the fake MPI implementation.

Greetings,
Kai
