%Doing many experiments with many cores is not easy and requires to access to a supercomputer with several hours for developing a code and then improving it.
In the following we present some experiments we could achieved out on the Hector
-architecture, the previous UK's high-end computing resource, funded by the UK
+architecture, a UK's high-end computing resource, funded by the UK
Research Councils. This is a Cray XE6 supercomputer, equipped with two 16-core
AMD Opteron 2.3 Ghz and 32 GB of memory. Machines are interconnected with a 3D
torus.
