In fact, this is for the same reason that I also try to use static linking:
I have been using two middle-size clusters as a normal user without root
Hence I cannot update the compiler/libraries... packages.
The binaries are installed via apt-get (Debian distro) and almost never
updated by the administrator.
Hence, they are not optimized for our hardware.
The default gfortran is still 4.1.2 and ifort is 10.0 20070426 (hence
I have made tests with more recent compilers and libraries installed
under my account and the system compilers indeed produce much slower codes.
I could go on this way and use LD_LIBRARY_PATH to point to my private
versions of the compilers/library but I have problems with the fact that
the SGE batch system uses an openmpi environment with an old version of
openmpi coherent with the compilers and glibc versions...
Furthermore, I would like to have the same computing environment on my
machine and on the cluster.
Maybe there is a clever way to deal with my problems than going for
static link, but I have already wasted quite some time trying other
solutions unsuccessfully. However, I would evidently appreciate if
someone could point me one! ;-)
