Determine if the following are true or false, if false correct the statement.
a) All CPUs of a shared memory multiprocessor can access all cache memories directly
b)All CPUs of a shared memory multiprocessor share the main memory
c)Shared address space cannot be implemented on a distributed-memory parallel computing system
Homework Answers
A) No, All CPUs of a shared memory multiprocessor can access all cache memories directly.Each CPU core's L1 caches are on the same die as the core and cannot be accessed by other cores. The cores are each connected to the L2 cache via the shared data bus.
B) Yes, All CPUs of a shared memory multiprocessor share the main memory.A multiprocessor is a computer system having two or more processing units each sharing main memory and peripherals, in order to simultaneously process programs.
C) Yes, Shared address space cannot be implemented on a distributed-memory parallel computing system. distributed shared memory (DSM) is a form of memory architecture where the memories can be addressed as one address space.

Question 9 Which of the following statements is true about memory system? Put the answer in the box. A. Cache memories are usually built by SRAMs, which have higher density and faster access speed than DRAM-based main memories. B. Secondary storages such as hard disk drive and solid-state drive are typically volatile memories. C. Compared to the associative cache mapping function, direct mapping function has more flexibility. D. Due to locality of reference, the basic transfer unit between cache and...

Example 4.2 For all three cases, the example includes the following elements: The cache can hold 64 Kbytes. Data are transferred between main memory and the cache in blocks of 4 bytes each. This means that the cache is organized as 16K = 214 lines of 4 bytes each. The main memory consists of 16 Mbytes, with each byte directly addressable by a 24-bit address (24 = 16M). Thus, for mapping purposes, we can consider main memory to consist of...
