The following options can be use with the `--enable-shm=` option to target different shared memory behaviours (default `shmopen`):

| `shmnone` | uses anonymous spaces, use only for 1 MPI rank per node |

These are the instructions to use the Generalised HMC on Grid version 0.7.0.

General
Introduction
=======
$$ \mathbf{X}\_{n,p} = \mathbf{A}\_{n,k} \mathbf{B}\_{k,p} $$
The general problem is to generate a Markov Chain distributed according to the action $$S(\psi)$$ in order to compute observables expectaction values.
$$ \langle O \rangle = \frac{1}{Z} \int O e^{-S(\psi)} D\psi $$
The Hybrid Monte Carlo approach is to introduce ficticious random momenta to construct an Hamiltonian $$H(\psi)$$ and generate
new configurations by integrating the corresponding Hamilton equations.
$$H(\psi) = \frac{1}{2} P^2 + S(\psi)$$
$$ \langle O \rangle = \int O e^{-S(\psi)} d\psi $$
