Super important
In case you see messages on the terminal(s) used requiring you to leave the machine from any one of the following users: * mau * cisterni * marcod * torquati please logout immediately after killing all your processes (foreground and backgroud). The machine is provided by the ITC and it may be the case it will be needed for short demos and experiments.
Machine address
The machine address is ninja.itc.unipi.it
Tools
All the intel tools may be found under
/opt/intel
Remember to
source /opt/intel/compilers_and_libraries/linux/bin/compilervars.sh intel64
in order to be able to use the compiler.
The machine also has a g++ compiler, but for the project you have to use the Intel compiler.
Programming framework
The cores in the machines are “kind of” Atom cores. Therefore the sequential performance of the single core is poor. You'll experience this while compiling. It takes seconds to compile simple C++ programs with the -O3 enabled.
