Fortran 95 compilers

The most convenient way to do the exercises might be on your own computer after installing a compiler. The main choices are listed below. gfortran is the most universal/popular, is completely free and can be used on Windows, MacOSX or Linux. For Windows, the silverfrost compiler seems to work well: this is free on your own computer, but on an ETH-owned machine it would be necessary to buy a license. Possibly the best compiler is the one by Intel, which works on Windows, MacOSX and Linux. ETH has a site license for it that employees can use, but unfortunately this isn't available for masters students. A drawback is that your computer must be networked so it can connect to the central ETH license server.

gfortran: Developed by the GNU, the free software foundation. See

silverfrost (for Windows): free for personal use, download from

Intel Fortran Compiler: ETH employees (e.g. doctoral students) can download from Documentation here.

Useful editors that highlight Fortran syntax: emacs or xemacs (unix-based); for MacOSX: aquamacs (here)

Free resources on the internet

1. A manual. A good one is the Intel Fortan Language Reference Manual.

2. Tutorials

3. General information and/or pages of links to relevant sites

4. Unix tutorials
