Dear All,<br><br>I have recently moved my Wien2k calculations to a new machine (Hector in the UK). This machine does not allow passwordless ssh and therefore disables the k-point parallel part of Wien2k. I therefore want to clarify some points about how MPI (chiefly lapw1_mpi) works in Wien2k.<br>
<br>If I run a calculation with say 5 k-points using 5 nodes that each have 24 cores, then will the MPI call of lapw1_mpi split the 5 k-points over the 5 nodes? Or will it simply run the k-points one at a time, using all 120 cores for each one?<br>
<br>Is there any documentation I can read about the MPI parallel strategy more generally?<br><br>Many thanks,<br>David Tompsett.<br>
