Expert Solution & Answer
Chapter 22, Problem 14E
Explanation of Solution
a)
- In a shared parallel architecture, neither the memory nor the disk is shared between processors.
- Consider a workload which consists of large number of small transactions and utilizes shared nothing parallelism.
- Intra –query parallelism is implemented while executing a single query in parallel on multiple processors and disks...
Explanation of Solution
b)
- When workload gets distributed amongst processors, some of processors might get a larger number of tuples than others and it is called a skew...
Explanation of Solution
c)
- Consider the given case with two tables, account and account type master record.
- Since most of the transactions access account records, so using intra-query parallelism to follow the below steps.
- Divide the data into equal numbers for the disks with each processor.
- Assign a home processor

Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2). Use as coin flip (source of randomness) an ID written in binary. use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown.
