If I create a program called hello which just contains the line "echo hello", then I do
"/bin/. hello" then I get permission denied. Is that what you mean? I might be lost in esoteric corners of Linux. What is "." under /bin ? There is no program there by that name. I've heard of "." as a shell built-in, but I haven't seen it prefixed by /bin before.

Appears you don't have permission to exec bash??

It should be using rsh to launch. There are 4 nodes involved (each 12 cores, 48 processes total). In the output file, I see 3 sets of messages as shown below. I assume I am seeing 1 set of messages for each of the 3 remote nodes where processes need to be launched: /bin/.: Permission denied. OPAL_PREFIX=/apps/local/falcon2014/openmpi: Command not found. export: Command not found.

LD_LIBRARY_PATH: Undefined variable. These look like errors you get when csh is trying to parse commands intended for bash. Does anyone know what may be going on here?
