Indicate whether each of the following statements is true or false:

(a) The processors in multiprocessor system communicate with each by reading and writing shared variable in a common memory. _________

(b) A UMA multiprocessors is a centralized shared-memory system in which the access time varies with the location of the memory word ___________

(c) In a parallel processor, to speed up the computation process a single program is decomposed and distributed onto several processors. _________

(d) Deadlock occurs when a packet waits for an event that cannot occur. _______

(e) A multicomputer that has the same processing units is called homogeneous whereas that with different processing units is called heterogeneous. __________

(f) A NUMA multiprocessors is a centralized shared-memory system in which the access time varies with the location of the memory word.__________

(g) Multiprocessor are called tightly coupled systems due to the high degree of resource sharing.___________

(h) In UMA model, to coordinate parallel events, synchronization and communication among processors are done through using shared variables in the common memory.__________

(i) Non-minimal routing algorithms always select the shortest message transmission.________

(j) In multicomputer system, interprocessor communication is done through message passing among the processors.__________
