<br>
<br><tt><font size=2>Your suggestion is to do something like (xml totally
untested and for sure with syntax-errors.. :-)</font></tt>
<br>
<br><tt><font size=2><clone id="A" clone-max="20"
priority="20"></font></tt>
<br><tt><font size=2> ...</font></tt>
<br><tt><font size=2></clone></font></tt>
<br><tt><font size=2><clone id="B clone-max="60" priority="10"></font></tt>
<br><tt><font size=2> ...</font></tt>
<br><tt><font size=2></clone></font></tt>
<br>
<br><tt><font size=2>Right?</font></tt>
<br><tt><font size=2>But how do i constraint the sum of A and B's running
on one node to the number of cpu-cores available? </font></tt>
