Parallel efficiency
===================
Benchmarks
==========
The determinant selection, MR-PT2 and diagonalization are parallelized with
distributed parallelism. Benchmarks for the [NH2-CH-NH2]+ molecule in the
aug-cc-pVDZ basis set are presented with up to 50 nodes (1800 cores) on
CALMIP's `Olympe`_ supercomputer, and 200 nodes (9600 cores) on GENCI's
`Irene`_ supercomputer. This represents an active space of 18 electrons
in 111 MOs.
- Nodes of Olympe have two Skylake sockets, 2x18 cores @ 2.3GHz.
- Nodes of Irene have two Skylake sockets, 2x24 cores @ 2.7GHz.
Convergence of the energy
-------------------------
.. figure:: _static/cn3_energy.png
:alt: Convergence of the energy.
Convergence of the variational energy, with and without the PT2 correction.
Both energies converge to the (frozen core) FCI energy.
The plot is displayed for the ground state and for the 1st excited state.

We present the parallel speedup curve, and the wall-clock time in seconds
required to compute one iteration for two wave functions measured on Olympe
and Irene.
