[mpich-discuss] MPICH2 for ARM

[Harald Schuster]

I added the config.log to this mail but i changed the pm from hydra to 
gforker only for testing and know the helloWorld example runs but when I 
tried a example with a broadcast the programm stops without any error 
but it not finishes. The gforker and hydra uses sockets or?
