OS_Structure_1c Spin_and_Exokernel   The context for this question is the same as the previous question. Exokernel uses a linear vector of time slots (or time quantum) to allot time for library OSes executing on top of Exokernel. Currently there are two library OSes running on top of the Exokernel.  OS1 is running a CPU-intensive long running ML training application  OS2 is running an interactive gaming application    c. [2 points] How does Exokernel maintain fairness for CPU time consumed by library OSes. 

Parallel_Systems_1 Shared Memory Machines 1. [2 points] Consider a NCC-NUMA architecture for a shared address space multiprocessor.  What guarantees are needed from the architecture to ensure that it provides sequential consistency memory model to the programmer?

Calculate the CFFA in Yr 1 and Yr 2.  

Calculate the CFFA in Yr 3 [Hint: CFFA in Yr 3 = OCF + NWC recovered + after-tax salvage,  where after-tax salvage = End value x (1 – tax rate)]

One of the characteristics of Arts and Crafts is the use of Assymetry.

Cucamongine (symbol Cg) is a fictional name for one of the halogens. Note that the name ends with -ine just as the halogen names used by ordinary chemists. According to the naming rules for the oxyanions of halogens, what would be the name of CgO2¯? 

What is the correct name for P₄O₁₀?

What would be the charge on an atom of Pb which only has 78 electrons?  [sign][magnitude]

What is the correct name for C₂Cl₄?

The names and symbols for the transition elements used in the fictional kingdom of Narnia are different from those used by the rest of the planet, except for silver, cadmium, and zinc. For the rest of the elements and chemical entities, the kingdom uses the same names and inorganic nomenclature rules as used by the rest of the world. If the name used for a transition metal is “narnium” (symbol Nr), what would be the name of NrSO4 in the kingdom of Narnia?
