2 nodes with each having 1 single core CPU, <br>2 nodes with each having 1 dual core CPU,<br>2 nodes with each having 1 quad core CPU,<br>2 nodes with each having 2 dual core CPUs, and<br>2 nodes with each having 2 quad core CPUs.<br>
<br>Then we could better say that there are 38 "pocessing elements" in this 10-nodes cluster. <br>Note that there are 10 motherboards in this cluster.<br> <br><br>
