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 -funroll-loops  files...
