Is there any information on this issue?
thanks.
I reset root keys for head and compute nodes and re-ran install script.
I was able to do the post_install however..... on the test I am getting
the following
Checking for NFS propagation of MPI preferences... Not yet
Checking for NFS propagation of MPI preferences... Not yet
Checking for NFS propagation of MPI preferences... Not yet
and on the command line:
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
X11 connection rejected because of wrong authentication.
Any ideas?
