• Latest version 0.3.1

Quick start

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()
