Suppose we have a computer system that contains the following:

$$ Two processors, each with ten cores that do not support hyper$-$threading $($i$.$e$.$ only one process$/$thread

per core$).$

$32$ independent $($No RAID$)$ SSD drives for processing.

There are a large number of single threaded jobs submitted into this system that each require the use of a

maximum of four SSD drives to complete their execution. Assume each job starts running with only three SSD

drives for a long period of time before requiring the fourth SSD drive for a short period near the end of its

execution. Also assume that there is an endless$/$infinite supply of these jobs. Suggest an alternative OS scheduling policy to improve SSD drive utilization and at the same time avoid

system deadlock $($where all processes can be deprived of required resources$).$ Your solution cannot

change the requirements for each job, only how the OS handles them.

a$.$ Write out your proposed policy.

b$.$ What is the maximum number of jobs that can be in progress at once?

c$.$ What are the minimum and maximum number of CPU cores that may be left idle because

of this policy?

d$.$ What are the minimum and maximum number of SSD drives that may be left idle because

of this policy?
