Description

The choice of the compiler (many clusters have several, a.o. gcc, intel, etc.) is important, as is the choice of the compiling options. This sessions reviews the strengths and weaknesses of the compilers and their optimal use.
Contents: The GCC Compiler and its options Intel Compiler Studio The different levels of code optimization Using external libraries Using configure and make Downloading and compiling source code Using linear algebra, signal processing libraries, etc.(BLAS, MKL, ACML, etc.)	Prerequisite: Being able to use SSH with private keys  Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.) Passive knowledge of C or Fortran
Type: Hands-on Target audience: Rookie programmers Must: This session is a must for anyone who needs to compile software from sources.
