A sample is a subset of the population from which raw data are obtained.     

23. Why is it necessary to piggyback with heparin when coumadin therapy is started?

We discussed both shared memory and message passing programming styles. From a programmer’s perspective, why would one be preferable to the other. You may choose either style and make an argument for why that one might be easier.

24. What test(s) must be used to monitor unfractionated heparin therapy and its complications?

In the Tomasulo algorithm, what do the dispatch and scheduling units do?

There are two database benchmark programs X and Y. Computer A can process 4 transactions per second of benchmark X and 4 transactions per second of benchmark Y. Computer B on the other hand can process 2 transactions per second of X and 7 transactions per second of Y. If we care equally about the performance of both benchmarks, which computer should we choose? Why? 

22. Which analyte from the choices below is a metabolite of methionine that is very labile and can indicate thrombosis risk when elevated?

Could you schedule the above code in 2 cycles if you had enough function units? Why or why not?

What is the point of studying computer architecture?

Assume that the above processor also experiences an average of .2 stall cycles per instruction due to data hazards. Accounting for both stalls due to control hazards and due to data hazards, what is the speedup of this processor over an un-pipelined processor?
