Hi Brian,
Some good news and bad news. According to the information provided
on http://www.open-mpi.org/faq/?category=running,
I have enabled X11Forward on all remote nodes, and
added the path to mpirun, which is "/usr/local/bin", on all node, and
"xhost +" on my localhost, and
set the D
XGrid does not forward X11 credentials, so you would have to setup an
X11 environment by yourself. Using ssh or a local starter does
forward X11 credentials, which is why it works in that case.

Hi Brian,
I got another problem in running an MPI job through XGrid. During the
execution of this MPI job it will call Xlib functions (i.e. XOpenDisplay())
to open an X window. The XOpenDisplay() function call failed (return
"null"), it can not open a display no matter how many processors that
Hi Brian,
I found the problem. It looks like xgrid need to do more work on fault
tolerance. It seems that xgrid controller distributed jobs to each available
agent only in certain fixed order, if one of the agents has problem in
communicating with the controller, all jobs failed, even when the

If you specified the use of a BTL component, you may have

Hi,
I have set up an Xgrid including one laptop and 7 Mac mini nodes (all are
duo core machines). I have also installed openMPI (openmpi 1.2.1) on all
nodes. The laptop node (hostname: sib) has three roles: agent, controller
and client, all the other nodes are only agents.
When I started "mpirun -
