Greetings! I have tried to run ring_c example test from a bash script. In this bash script, I setup PATH and LD_LIBRARY_PATH(I donot want to disturb ~/.bashrc, etc), then use a full path of mpirun to invoke mpi processes, the mpirun and orted are both on the PATH. However, from the Open MPI message, orted was not found, to me, it was not found only on slave nodes. Then I tried to set the --prefix or -x PATH -x LD_LIBRARY_PATH to hope these envars passed to slave nodes, but it turned out they are not forwarded to slave nodes.
On the other hand, if I set the same PATH and LD_LIBRARY_PATH in ~/.bashrc which shared by all nodes, mpirun from bash script runs fine and orted could be found. This is easy to understand though, but I realy do not want to change ~/.bashrc. It seems the non-interactive bash shell does not pass envars to slave nodes. Any comments and solutions? Thanks, Yiguang
