Question $4$: Threads and Concurrency

$[24]$

Using Amdahl's law, calculate the speedup gain for the following applications:

a$.50$ percent parallel with $($a$)$ eighteen processing cores and $($b$)$ six processing cores

$(4)$

b$.67$ percent parallel with $($a$)$ seven processing cores and $($b$)$ two processing cores

$(4)$

c$.80$ percent parallel with $($a$)$ four processing cores and $($b$)$ eight processing cores

$(4)$

Consider the following code segment:$($a$)$ How many unique processes are created?$($b$)$ How many unique threads are created?$3)$ Determine if the following problems exhibit task or data parallelism:$\mathrm{.}3$a$.$ Using a separate thread to generate a thumbnail for each photo in a collection$(2)$b$.$ Transposing a matrix in parallel$(2)$c$.$ An ETF application that uses different threads to extract data from multiple data sources, transform the extracted data and load the transformed data in the same database$(2)$
