Answer:

Architects have initiated several efforts in leveraging the Dark Silicon to design application-specific and accelerator-rich architectures.Recently, researchers have explored how Dark Silicon exposes new challenges and opportunities for the EDA community. In particular, they have demonstrated the thermal, reliability (soft error and aging), and process variation concerns for Dark Silicon many-core processors.

Using arrangement (a), how many rb atoms could be placed on a square surface that is 9.5 cm on a side? the diameter of a rubidiu

Leviafan [203]

Part a

Answer: $3.64\times10^{16}$

For the arrangement considered in part a, all the atoms are aligned side by side along the side of the square surface.

Along one side of the square, the number of atoms that could fit $=\frac {length\hspace{1mm}of\hspace{1mm}side}{diameter\hspace{1mm}of\hspace{1mm}atom}=\frac{9.5\times10^{-2}m}{4.95\times10^{-10}m}=1.91\times10^8 atoms$

This is along one side. On the entire surface:

Number of atoms $= (1.91\times10^8 )^2=3.64\times10^{16} atoms$

Part b

Answer: $4.23\times10^{16}$

consider the attached figure below:

The next layer of atoms are filled in the depressions of the first layer. The vertical distance between the two atoms would change. Consider an equilateral triangle drawn by joining the centers of the three atoms.

The atoms along the horizontal side would be aligned side by side; same as above $=1.91\times10^8 atoms$
