Show me the steps to solve $13)$ The SIMD parallel architecture $($Single$-$Instruction$-$Multiple$-$Data$)$ is the most convenient to use for task parallelism.

True False

$14)$ Assume a link between two processors has a latency of $1$ ms and a bandwidth of $\backslash (10\backslash$mathrm$\{$~Gb$\}/\backslash$mathrm$\{$s$\}\backslash ).$ The time it takes to transmit a workload of $100$ MB between the two processors is about $81$ ms $.$

True False

$15)$ In shared$-$memory parallelism, cache coherence refers to multiple CPU's using the same cache.

True False

$16)$ In the implementation of cache coherence, directory$-$based methods have less hardware overhead than snooping methods.

True False

$17)$ In non$-$blocking asynchronous communication, the send$()$ function returns immediately but the recv$()$ function returns once acknowledgment is sent back to the transmitter.

True False

$18)$ In synchronous communication between two processors, the send$()$ function returns once the sender receives acknowledgment that the transmitted data resides in the address space of the receiver.

True False

$19)$ In instruction$-$level parallelism, two instructions or more are executed per clock cycle and as such it is similar to a pipelined architecture.

True False

$20)$ In Python, GIL stands for Global Interface Layer.

True False
