[image: image.gif]Dear All,
I am trying to run QMMM-MD using orca-namd2.
But it happens to be too slow, I wanted to know if I am doing something
wrong or is there a better way.
I have a CPU node with 40 cores (and 4 unused GPU), my calculations of
75,000 atoms QMMM-Minimization takes 4 days.
NAMD2 -> namd2 +p22 Min.conf
ORCA -> qmConfigLine "% PAL NPROCS 20 END" (from Min.conf)
# Number of simultaneous QM simulations per node
Thanks and regards,
