Hello, I followed the call to test the rc1, but a simple test programm hangs, but non deterministic. all but one orted have quit. but no cpu eating from orted or mpirun.
The test system is a xeon cluster with myrinet interconnect. the outouts are splited into two mails (100kb limit) Bert Wesarg

Another transport will be used instead, although this may result in
lower performance.
