Dear Haicheng,
<div>Quantum transport is not parallelised yet - though it would be relatively straightforward to do so. It’s on the list of things to do for a future release. If anyone is interested in carrying out the coding themselves and contribute it to the code,
please get in touch with me and I’d be happy to advise. </div>
<div>Best wishes,</div>

<div>Dear all,<br>
I found that serial calculation of wannier90 might be time consuming. However, wannier.x is serial executable. I wonder if there is way of calculate transport properties (quantum not boltzmann) using MPI executable file?<br>
