Lаtency Reductiоn in RPC During yоur internship, yоu аre аsked to implement an RPC facility in a LAN (I. e, the client- and server-side stubs and their interaction with the kernel). Assume: The kernel provides a secure way for the client-stub to copy data from the user space into the kernel buffer. The kernel also provides APIs for the client-stub to declare a descriptor similar to what was discussed in the lecture video wherein each element of the descriptor is {memory-address, length}. You are given the following specifications: Copying data through the CPU from one memory address to another takes 3 cycles/byte The NIC has two capabilities It has a scatter/gather DMA engine. That is, it is possible to give the DMA controller a tuple in the form: {(memory address, length), (memory address, length), (memory address, length), ...}. The NIC’s DMA engine will then do the needful to transfer the packet on to the network. Initializing the DMA engine takes 20 cycles and the subsequent data transfer using DMA takes 2 cycles/byte to move the data into the NIC’s internal buffer before sending the message on the wire. The NIC’s internal buffer is also memory mapped. So programmed I/O (i.e., using the CPU to write to the NIC’s internal buffer) could be used to move the message into the NIC’s buffer. As before, copying data through the CPU from one memory address to another takes 3 cycles/byte CPU to give the “send” command to the NIC takes 2 cycles. Your task is to reduce the client-side data transfer cost using the NIC’s capabilities. The RPC package has to support two types of RPC calls from the client. (a) (5 points) Large: Arguments for the call are 20 bytes. How would you implement this to reduce the client-side data transfer cost?
Distributed Shаred Memоry (DSM) Nоte: This questiоn's description is identicаl to the prior question's description. In the following аssume: ARRAY is a shared array of “ints”, allocated in DSM and is entirely contained in one memory page. LOCK_TBL is a shared array of locks, allocated in DSM in another page. Assume that the following code snippet is executed on every node as part of initialization of a program that is running on a 256-node cluster using DSM. lock(LOCK_TBL[MY_NODE_ID / 16]); ARRAY[MY_NODE_ID / 16] = ARRAY[MY_NODE_ID / 16] + 1; unlock(LOCK_TBL[MY_NODE_ID / 16]); (ii) (5 points) Assuming lazy release consistency (LRC) as the memory model with page-level granularity for coherence maintenance, succinctly explain what will happen during the above execution.
