Compilers:Intel

Intel offers compilers that will generate binaries that are better tuned for their target archtecture than those generated by the Gnu compilers.

Licensing

We use the free non-commercial licenses offered on Intel's website. If a host already has the compilers installed, check /opt/intel/licenses/ for the license files. They do not seem to be tied to a particular version, and do not expire. If you don't see a license, just request a new one.

Installing

The installation process is pretty well documented by Intel inside <package-dir>/INSTALL.txt. I usually install the complete package. I also had some issue entering the license number in the installer by hand, the only thing I could get to work was copying the .lic files to a temporary location on the filesystem and then pointing the installer to their path.

wget http://registrationcenter.cps.intel.com/irc_nas/69/l_cc_c_9.0.032.tar.gz
tar -zxvf l_cc_c_9.0.032.tar.gz
cd l_cc_c_9.0.032
less INSTALL.txt 
./install.sh

Testing

Here's an easy way to make sure the compiler works:

cat <<EOF > hello-test.cpp 
#include <iostream>
using namespace std;

int main(int argc, char **argv)
{
  cout <<"Hello"<<endl;
  return 0;
}
EOF
source /opt/intel/cce/9.0/bin/iccvars.sh
icpc hello-test.cpp -o hello
