About
g95 and gfortran
There are quite a few Fortran compilers available. gfortran comes with the Linux
system and you can fetch the Intel-compiler
yourself (provided you have a fair amount of free disk space).
I no longer support the Fortran90-compiler, g95.
You (may) need to change the LD_LIBRARY_PATH as well (this environment
variable tells the dynamic loader where to look for libraries).
To get faster code -O3 may not be enough on some of the tests, you may need to
ask the compiler to unroll loops as well.
Type: gfortran -O3
