Hi Dan,
The output for mpicc -show is:

The tail of neb_gb_partial_XX.out files is :

I ran make test.neb with 8 threads, the outcome was the same as 4 threads.

What is the output of 'mpicc -show' (where mpicc is the mpi command
used to compile your parallel version of amber)? Did you use the
./configure_openmpi script or is this a version of openmpi that came
with your system?

Typically the error will be printed at the end of the file. Try 'tail
neb_gb_partial_*.out' and see what prints.

15 minutes is probably too long. I will run some tests with openmpi
and see if I can recreate your problem.

Not too worrisome; this means you don't have the development version
of the X libraries (including header files) which are necessary for
compiling e.g. Xleap. If you don't use xleap you can specify the
'-noX11' option to configure. Otherwise you need to install the
necessary package, and possibly set the XHOME and/or XLIBS variables
in config.h. So for example on my fedora14 machine if I type:
$ yum list libXt-devel*
Loaded plugins: langpacks, presto, refresh-packagekit
Adding en_US to language list
Available Packages
libXt-devel.i686 1.0.7-1.fc13
fedora
libXt-devel.x86_64 1.0.7-1.fc13
fedora
I can see I dont have the libraries installed, so I can do something
like 'yum install libXt-devel.x86_64' and everything should be OK.
I'll get back to you and let you know if I can reproduce the error.
