Jаne wоuld like tо bоrrow $850 for exаctly one yeаr, so that she can buy a brand-new lawn mower for the lawn-mowing business she is starting. Jane’s local bank agrees to lend her the money only if she is willing to pay back the full amount plus an extra $50, for a total repayment amount of $900.What is the annual interest rate on Jane’s loan from her bank? Give the answer as a percentage, rounded to one decimal place. For example, 0.067 or 6.7% would be entered as 6.7
Prоblem 1. (1 pоints) Mentiоn two key rаtionаle behind In-network computing. Problem 2. (3 points) Recаll implementing a key-value cache using Match-Action stages of a programmable switch. Suppose we have four entries in the cache -- {Key: A, Value: A0 A1 A2}, {Key: B, Value: B0 B1}, {Key: C, Value: C0}, {Key: D, Value: D0 D1}. Below is the (partial) implementation of the cache using four Match-Action stages. The operations for reading and updating the cache are implemented using the process_array action shown below. Fill the empty bitmap and index fields in Stage 1 and the empty register array values in Stages 2--4. Recall a bitmap indicates the register arrays that store the key's value (i.e., a value of 1 for bitmap[i] indicates that register array i stores the key's value). Assume most significant bit (MSB) of bitmap is indexed 0. index indicates the slot number where a value is stored. Problem 3. (3 points) Figure below shows the VMs for three tenants --- tenant R (whose VMs R1, R2, R3 are shown in Red), tenant G (whose VMs G1, G2, G3 are shown in Green), and tenant B (whose VMs B1, B2 are shown in Blue). The minimum bandwidth guarantee as part of the Service Level Objective (SLO) for tenant R is 2 Gbps, tenant G is 5 Gbps, and tenant B is 3 Gbps. Each host has bandwidth capacity of 10 Gbps. There are four active flows in the network: R1(rightarrow)R3, R2(rightarrow)R3, B1(rightarrow)B2, and G1(rightarrow)G3. The rate for flow G1(rightarrow)G3 is 5 Gbps, while the rates for the remaining three flows are not known to you. Based on this information, please answer the questions below. (a) What will be the rate feedback sent by R3 and B2 to R1, R2, and B1 in EyeQ? Rate feedback from R3 to R1: Gbps Rate feedback from R3 to R2: Gbps Rate feedback from B2 to B1: Gbps (b) What will the rates for flows R1(rightarrow)R3, R2(rightarrow)R3, and B1(rightarrow)B2 finally converge to in EyeQ? Rate for flow R1(rightarrow)R3: Gbps Rate for flow R2(rightarrow)R3: Gbps Rate for flow B1(rightarrow)B2: Gbps Problem 4. (1 point) Why does an RDMA network need Priority Flow Control (PFC)? Why do we need a congestion control protocol like DCQCN on top of PFC? Problem 5. (2 points) DCQCN is a congestion control protocol designed for lossless networks. But given that there are no per-packet ACKs in a lossless network, how is the sending rate of a flow increased in DCQCN? Provide the condition(s) for rate increase and the corresponding equation(s). Problem 6. (2 points) Suppose you are a cloud provider and you receive a request to provision a VM with 10 GB of memory. Suppose you know that at any time, the VM only touches up to 6 GB of memory. Answer the questions below assuming you are using Pond's memory allocation algorithm. (a) Suppose the VM is running latency sensitive workload. How much memory should you allocate to the local node on which the VM is running and how much memory should you allocate to the remote memory pool? (1 point) Local memory: GB Remote memory: GB (b) Now answer the above question assuming that the VM is running latency insensitive workload. (1 point) Local memory: GB Remote memory: GB Problem 7. (4 points) Consider a RotorNet network with 5 nodes -- A, B, C, D, and E. Below is the static permutation schedule used to reconfigure the network. (a) Suppose nodes A, B, C, and D all send 1 packet each destined to final destination E at time 0. Fill the table below with the intermediate node that each packet goes through on its way to E. If a packet does not go through an intermediate node (i.e., it is delivered directly to node E), fill the corresponding table entry with "None". (2 points) (b) Following from the above question, at what time does each packet arrive at node E. Assume zero propagation delay, i.e., a packet transmitted at time (t) will reach the next hop at time (t) itself, and a node can only transmit one packet in each time slot. (2 points) Problem 8. (4 points) Consider a 3-node system performing Ring AllReduce. Recall that Ring AllReduce iteratively performs Reduce-Scatter followed by AllGather for a total of (2(N-1)) iterations, where (N) is the number of nodes. For each iteration shown below, fill the tensor values at each node and the tensors exchanged between nodes. (4 points) Congratulations, you are almost done with this exam.

Write аn essаy аddressing the questiоns belоw. Yоur responses to questions 1, 2 and 4 should be brief, whereas your response to question 3 should occupy at least half the space in your essay. This is an expository (informative) essay, so it does not need an argument or thesis statement. However, it does need paragraphs and clear organization. 1. Identify the mission you visited. What is the earliest date mentioned at the mission? 2. According to the public presentation at the mission, what events or activities took place there—i.e. what was the site’s significance—during the colonial period? (Remember: keep your response brief. It is not your essay’s main purpose to convey information given at the mission.) Optional: Do you have any other comments on what might have been going on there around the earliest date(s) mentioned? 3. How would you place the history of this particular site in the broader context of colonial Latin American history? In other words, how does the site reflect or illustrate patterns that you have studied in this course in readings or lectures? In particular, how does it reflect patterns of colonial Latin American frontiers? (You may mention specific course materials. Please cite or identify them clearly.) 4. How is colonial-era history presented at the mission? Do you think any aspect(s) of the mission’s colonial history is missing from the presentation? Explain. Optional questions What do you think was at this location (or what was going on there) before the earliest date mentioned in the public presentation of history at the mission? If you were in charge, would you change or add anything to the presentation? If you were going to take a group of students studying colonial Latin America to this mission, what would you present to them? Is this information already included in the presentation there, or would you have to change or add to the current presentation? Any other comments about the mission and/or about your visit there?
