Fill in the blank

(a) A _______________________________ processor relies on the compiler to find independent instructions to execute in the same cycle.

(b) A ________________________ processor executes the same instruction in parallel on multiple functional units on different data.

(c) A ______________________ multiprocessor is one where any processor can directly access any memory on the computer, even if it is on a memory bank local to another processor.

(d) It is possible to implement a shared memory model on a distributed memory multiprocessor by using a ________________________ cache coherence protocol.

(e) A ________________________ bit in a cache ensures that unmodified cache lines are not written to main memory when evicted from cache
