This number specifies the number of requested ``worker nodes'' for your
calculation. If EGO is not able to access that number of nodes,
fewer nodes my be used by EGO. One node works as a master and does not
directly participate in the molecular dynamics calculation.
The ``master node'' handles initialization, data output, etc. Make sure that
there is one additional node available for that task. One achieves best
for n requested nodes, if there are n+1 ``physical nodes''.
Minimum value for this variable is 2.
If, in case of PVM, EGO is not able to access the requested number of
``physical nodes'', some ``virtual nodes'' are created on a ``physical node'',
which will clearly lead to a poor performance.
However, this may be useful during program development, as small molecules can
then be tested on a single workstation.
