Do you know if is it possible to install C++ and Fortan compiler in a machine with with DEX Procesador Intel Core i5-3450 (3.1,6MB,1155) and Fedora 17?
Which linux version it sould be better?
You will not be able to use an Itanium compiler with these "Ivy Bridge" CPUs. If you choose to install Intel compilers on such a recent linux distro, the latest "XE 2013" compilers would probably be best.
Further questions should be asked on a relevant forum, such as the C++ or linux Fortran forums.
You are right to choose a fairly up to date linux distro. There are distros, such as Red Hat or CentOS 5.9, which are designed to run on these CPUs but without support for AVX compilation.
