Normally yes. There appears to be a problem with how X10DT sets up
ssh-agent forwarding that surfaces with the sockets x10rt implementation
unless X10_HOSTLIST is set to localhost (setting it to localhost causes
x10rt_sockets to use fork instead of ssh to create the processes for each
place). We are able to reproduce the problem, but do not have a fix yet.
The intent is that this functionality should work and support launching
across multiple computers from X10DT. In the meantime, you could use X10DT
to build and then launch on the command line from the remote machine using
X10_HOSTLIST to run across multiple machines.
