Amber users:
I have been able to compile and successfully run Amber8 using
Intel's ifort compiler and Math Kernel Library; however, I was told that
the Portland Group's compilers might improve performance, so I have been
trying to recompile Amber8 using the Portland Group compilers. I have a
dual processor opteron system using Fedora Core 2 - I have installed
MPICH but I have not tried compiling Amber8 using those libraries
though. After using 'configure -opteron pgf90' and running 'make
serial', it successfully compiles but when I try and run a simple
minimization, I get a segmentation fault error. I found that the
configure script had the directory of the ACML and LAPACK libraries
hardcoded and did not point at the correct directory, so I changed it to
my local installation:
if [ -e $PGI/linux86/5.2/lib/liblapack.a ]; then .
instead of:
if [ -e /usr/pgi/lib/liblapack.a ..
This did not fix the problem however.
The Portland group's website offers alternate versions of the configure
script that should fix any problems, but I have not been able to get
them to work.

When I use their configure script and run 'configure -nopar -opteron
-acml -lapack pgf90' followed by 'make serial', I get the following
error, after which compilation halts:
