Red Hat (7)
I'm attaching a makefile for RedHat7 ("Makefile.rhel7"). (This also
works with RHEL6) To compile using it, you need to install the
following standard packages with yum:
gcc-c++ openmpi-devel fftw-devel
Makefile.mpi does the same thing *and* enabled vectorization. the
benefit from using fftw instead of the internal FFT is almost always
negligible.

Ubuntu (14.04)
I'm attaching a slightly altered version of "Makefile.ubuntu" and
"Makefile.ubuntu_simple", which omit the "-g" flag. (It looks like
someone forgot to take it out.) As before, to compile the full
i don't think so. in fact, it is highly recommended to *use* the -g
flag for any self-compiled binaries as it allows to do more thorough
debugging and profiling of the executable at no additional cost
(except for a little bit of disk space). removing the debug info makes
it massively harder to associate certain areas of code with the
corresponding source file. if you absolutely feel including debug-info
to be wasteful, then you should do as the rpm packages do and strip
the debug info into a separate file and then put it into a suitable
location.

My mistake. Both makefiles work in Red-Hat-EL-7 (Makefile.mpi &
Makefile.rhel7). If I notice a non-trivial speed difference between
the two versions, I'll post again, but I doubt it.
In the past, we were having difficulty getting "make mpi" to to work
in red hat EL-6 or EL-7, so we changed the makefile and reinstalled
the OS, and things magically worked again. (Apparently it was
reinstalling the OS which did the trick, and not the makefile.)
Thanks!

I'm happy to be wrong about this too.
Thanks again.
