Fortran Compilers in DAMTP

The older compiler for Fortran 77 is called f77 - note that on the Linux machines this is actually g77 and is a very old version which should not be used unless you have no choice. It will be removed at some point fairly soon.

Compilers for Fortran 90/95 have different names depending on which operating system you are using:

   Machine type              Compiler name

   Linux/x86 (32-bit)        ifort
   Linux/x64_86 (64-bit)     ifort64

   Linux (both 32/64bit)     gfortran

Note that not all types of systems have Fortran 90/95 compilers.

The Intel Fortran compiler is called ifort and version 9.1 is available on Intel based systems running our installations of Linux. The associated debugger is called iidb.

We only have 2 floating licences for this compiler but as they are only used during the compilations this will hopefully be enough. If you get warnings about a lack of licences please contact help with the error messages.

We now have version 11.1 of the Intel compilers available for testing, and these should become the default version within a few weeks.
