Hello, First I would like to thank you for all your answers. :)
I do all my tests on the mom nodes requested through the queuing system. In other cases I cannot access the compute nodes. Also the installation needs to see the appropriate libs and header files - which are not available on the login nodes here. ;) In my first test I used mpirun as this was build with alps support and should by this be able to handle the startup on the compute nodes. I followed your suggestions and tried aprun too which gave me the same error. A installation using the pmi 2.1.4 interface did not report errors but hangs silently during the startup process.
