[Pw_forum] Debian Platforms and Fortran Compilers

[Paul M. Grant]

Some info possibly useful to other PWscf users.

 

I've found it too difficult to go through all the turmoil required to
install the Intel compiler on (K)ubuntu 7.10.the install script is
incredibly buggy.  So I switched to gfortran, which installs effortlessly
and without the additional baggage of "license verification," and found, at
least for my tests (e.g., example07), there are no significant differences
in cpu execution times.fractions of seconds over many hours.  But, it is far
less tolerant of typos in namelist strings (e.g., missing apostrophes).but,
wait.this might be due to "improvements" in 3.2.3 which I also upgraded to
at the same time!
