The most important characteristic of Massively Parallel Computing systems is the topology of the network that means how
to connect the processors with each other so that provides fast data transfer and low cost.
In this research, we will find new l
ink networks that provide speed
in the transport and low cost compared with other traditional
networks for connecting processors.
Interconnection networks are divided to be static networks so that
fixed links between processors, while dynamic networks so that
every communication between two processors owns more than one path.
Each network differs from the other in cost which express the
number of links within this network, and speed which express the
network diameter and bisection. The network is best whenever the
cost is less and diameter is less but bisection is larger.
In this research I compared between these networks and then look
for new networks through hybridization between core networks.
After that I studied the specification of hybrid interconnections
compared with its constituent core networks.
This research aims to test some equations, used in different regions and forest types,
for assessing the total height of shoots in the oak )Quercuscalliprinos) Maquis forests,
depending on diameter,which enable the estimation of volumes without mea
suringthe
height of these shoots. This is very important to saveefforts, time and moneyinvested by
foresters.
The study included102 samples distributed within the most important oak forests on
the eastern exposition of the coastal mountains. The plots have rectangular shape with 50
shoots at least. The plots vary in shoot density, soil fertility and Maquiage. In each sample
we measured the diameter at a height of 30 cm, the total height of (10-20) shoots of various
diameters (low-medium-dominant).
