• Latest version 0.3.1

When the script of the serial PySCF version works, MPI can be activated by importing mpi4pyscf and replacing the corresponding initialization statements in the script. For examples::

import pyscf
mol = pyscf..M(atom='''
O    0.   0.       0.
H    0.   -0.757   0.587
H    0.   0.757    0.587''',
               basis='cc-pvtz')

# Serial mode
from pyscf import scf
mf = scf.RHF(mol).run()

# MPI parallelism
from mpipyscf import scf
mf = scf.RHF(mol).run()

pip install mpi4pyscf
