Hint: This is visible in the graph above shown as a slight increase in L2 miss service time for large data sets, and is 15 ns in the graph above. Hint: Take independent strides that are multiples of the page size to see if the TLB if fully-associative or set-associative. Hint: Look at the speed of programs that easily fit in the top-level cache as a function of the number of threads. Hint: Compare the performance of independent references as a function of their placement in memory. Before the Precharge of a new read operation can begin, the Precharge, Activate, and CAS latencies of the previous read operation must elapse. Of this time, the memory channel is only occupied for 4 ns. To keep the channel busy all the time, the memory controller should initiate read operations in a bank every 4 cycles. Because successive read operations to a single bank must be separated by 39 cycles, over that period, the memory controller should initiate read operations to unique banks. It can then initiate a new read operation to each of these 10 banks every 4 cycles, and then repeat the process.

Another way to arrive at this answer is to divide by the The sequence of operations is as follows: Precharge begins at time 0; Activate is performed at time 13 ns; CAS is performed at time 26 ns; a second CAS the row buffer hit is performed at time 30 ns; a precharge is performed at time 43 ns; and so on. In the above sequence, we can initiate a row buffer miss and row buffer hit to a bank every 43 ns. So, the channel is busy for 8 out of every 43 ns, that is, a utilization of The second would be serviced 39 ns later, that is, at time 82 ns. The third and fourth would be serviced at times and ns. Note that waiting in the queue is a significant component of this average latency. If we had four banks, the first request would be serviced after 43 ns. Assuming that the four requests go to four different banks, the second, third, and fourth requests are serviced at times 47, 51, and 55 ns.

This gives us an average memory latency of 49 ns. The average latency would be higher if two of the requests went to the same bank. Note that by offering even more banks, we would increase the probability that the four requests go to different banks. We have also seen that by having more banks, we can support higher parallelism and therefore lower queuing delays and lower average memory latency. Thus, even though the latency for a single access has not changed because of limitations from physics, by boosting parallelism with banks, we have been able to improve both average memory latency and bandwidth. This argues for a memory chip that is partitioned into as many banks as we can manage. However, each bank introduces overheads in terms of peripheral logic near the bank. To balance performance and density cost , DRAM manufacturers have settled on a modest number of banks per chip—8 for DDR3 and 16 for DDR4. Exercises 2. The access time of the direct-mapped cache is 0.

This makes the relative access times 1. The access time of the 16 KB cache is 1. Direct mapped access time ¼ 0. The average memory access time of the current 4-way 64 KB cache is 1. The AMAT of the way-predicted cache has three components: miss, hit with way prediction correct, and hit with way prediction mispredict: 0. The cycle time of the 64 KB 4-way cache is 0. This provides 0. With 1 cycle way misprediction penalty, AMAT is 1. The serial access is 2. Chapter 2 Solutions 2. The access time is 1. The pipelined design not including latch area and power has an area of 1. The banked cache has an area of 1. The banked design uses slightly more area because it has more sense amps and other circuitry to support the two banks, while the pipelined design burns slightly more power because the memory arrays that are active are larger than in the banked case.

With critical word first, the miss service would require cycles. It depends on the contribution to Average Memory Access Time AMAT of the level-1 and level-2 cache misses and the percent reduction in miss service times provided by critical word first and early restart. If the percentage reduction in miss service times provided by critical word first and early restart is roughly the same for both level-1 and level-2 miss service, then if level-1 misses contribute more to AMAT, critical word first would likely be more important for level-1 misses. Assume merging write buffer entries are 16B wide. Because each store can write 8B, a merging write buffer entry would fill up in 2 cycles. The level-2 cache will take 4 cycles to write each entry.

A nonmerging write buffer would take 4 cycles to write the 8B result of each store. This means the merging write buffer would be two times faster. With nonblocking caches, writes can be processed from the write buffer during misses, which may mean fewer entries are needed. What differs is the time spent servicing L1 misses. The best design is case b with a 3-level cache. Going to a 2-level cache can result in many long L2 accesses cycles looking up L2. Going to a 4-level cache can result in many futile look-ups in each level of the hierarchy. Therefore, if the objective is to minimize overall MPKI, program B should be assigned as many ways as possible. A instruction program would finish in cycles, that is, ns. The power consumption would be 1 W for the core and L1, plus 0. The energy consumed would be 1. Next, consider a PMD that has no L2 cache. Energy ¼ 1. Energy ¼ 2. Therefore, of these designs, lowest energy for the PMD is achieved with a KB L2 cache.

This reduces L2 and memory access power. This is slightly offset by the need for more cache tags and higher tag array power. However, if this leads to more application misses and longer program completion time, it may ultimately result in higher application energy. For example, in the previous exercise, notice how the design with no L2 cache results in a long execution time and highest energy. b A small cache size would lower cache power, but it increases memory power because the number of memory accesses will be higher. As seen in the previous exercise, the MPKIs, latencies, and energy per access ultimately decide if energy will increase or decrease. c Higher associativity will result in higher tag array power, but it should lower the miss rate and memory access power.

It should also result in lower execution time, and eventually lower application energy. A newly fetched block is inserted at the head of the priority list. When a block is touched, the block is immediately promoted to the head of the priority list. When a block must be evicted, we select the block that is currently at the tail of the priority list. b Research studies have shown that some blocks are not touched during their residence in the cache. An Insertion policy that exploits this observation would insert a recently fetched block near the tail of the priority list. The Promotion policy moves a block to the head of the priority list when touched.

It may also be reasonable to implement a Promotion policy that gradually moves a block a few places ahead in the priority list on every touch. In this approach, each program receives a subset of the ways in the shared cache. When providing QoS, the ways allocated to each program can be dynamically varied based on program behavior and the service levels guaranteed to each program. When providing privacy, the allocation of ways has to be determined beforehand and cannot vary at runtime. Note that we already implement a priority list typically based on recency of access within each set of the cache.

This priority list can be used to map blocks to the NUCA banks. Note that such block migrations within the cache will increase cache power. They may also complicate cache look-up. A 2 GB DRAM with parity or ECC effectively has 9 bit bytes, and would require 18 1 Gb DRAMs. A burst length of 4 reads out 32B. This is similar to the scenario given in the figure, but tRCD and CL are both 5. In addition, we are fetching two times the data in the figure. In the case of a bank activate, this is 14 cycles, or The CPI added by the level-2 misses in the case of DDR is 0. Meanwhile the CPI added by the level-2 misses for DDR is 0. Thus, the drop is only 1. From Fig. If consecutive blocks are in the same bank, they will yield row buffer hits. While this reduces Activation energy, the two blocks have to be fetched sequentially.

The second access, a row buffer hit, will experience lower latency than the first access. If consecutive blocks are in banks on different channels, they will both be row buffer misses, but the two accesses can be performed in parallel. Thus, interleaving consecutive blocks across different channels and banks can yield lower latencies, but can also consume more memory power. The system built from 1 Gb DRAMs will have twice as many banks as the system built from 2 Gb DRAMs. Thus, the 1 Gb-based system should provide higher performance because it can have more banks simultaneously open. The power required to drive the output lines is the same in both cases, but the system built with the x4 DRAMs would require activating banks on 18 DRAMs, versus only 9 DRAMs for the x8 parts. The page size activated on each x4 and x8 part are the same, and take roughly the same activation energy.

Thus, because there are fewer DRAMs being activated in the x8 design option, it would have lower power. The key benefit of closing a page is to hide the precharge delay Trp from the critical path. If the accesses are back to back, then this is not possible. This new constrain will not impact policy 1. The application and production environment can be run on a VM hosted on a development machine. Applications can be redeployed on the same environment on top of VMs running on different hardware. This is commonly called business continuity. Applications running on different virtual machines are isolated from each other. The median slowdown using pure virtualization is These have no real work to outweigh the virtualization overhead of changing protection levels, so they have the largest slowdowns. As of the date of the computer paper, AMD-V adds more support for virtualizing virtual memory, so it could provide higher performance for memoryintensive applications with large memory footprints.

If prefetched blocks are placed in the cache or in a prefetch buffer for that matter , they may evict other blocks that are imminently useful, thus potentially doing more harm than good. A second significant downside is an increase in memory utilization, that may increase queuing delays for demand accesses. This is especially problematic in multicore systems where the bandwidth is nearly saturated and at a premium. These results are from experiments on a 3. Similar behavior with different flattening points on L2 and L3 caches are observed. This shows the importance of all caches. Among all three levels, L1 and L3 caches are more important. This is because the L2 cache in the Intel® Xeon® Processor X is relatively small and slow, with capacity being KB and latency being around 11 cycles. For a recent Intel i7 processor 3. With a 11 cycle miss penalty, this means that without prefetching or latency tolerance from out-of-order issue, we would expect there to be an extra cycles per 1 K instructions due to L1 misses, which means an increase of 3.

The measured CPI with the 8 KB input data size is 1. Without any latency tolerance mechanisms, we would expect the CPI of the KB case to be 1. However, the measured CPI of the KB case is 3. Chapter 3 Solutions Case Study 1: Exploring the Impact of Microarchitectural Techniques 3. Each instruction requires one clock cycle of execution a clock cycle in which that instruction, and only that instruction, is occupying the execution units; since every instruction must execute, the loop will take at least that many clock cycles. To that base number, we add the extra latency cycles. The answer is 25, as shown in Figure S. Remember, the point of the extra latency cycles is to allow an instruction to complete whatever actions it needs, in order to produce its correct output. Until that output is ready, no dependent instructions can be executed. So, the first fld must stall the next instruction for three clock cycles.

The fmul. d produces a result for its successor, and therefore must stall 4 more clocks, and so on. Assume results can be immediately forwarded from one execution unit to another, or to itself. Further assume that the only reason an execution pipeline would stall is to observe a true data dependency. Now how many cycles does the loop require? The answer is The fld goes first, as before, and the fdiv. d must wait for it through four extra latency cycles. After the fdiv. d comes the fmul. d, which can run in the second pipe along with the fdiv. The fld following the fmul. d does not depend on the fdiv. d nor the fmul. d, so had this been a superscalar-order-3 machine, that fld could conceivably have been executed concurrently with the fdiv. d and the fmul.

Since this problem posited a twoexecution-pipe machine, the fld executes in the cycle following the fdiv. N might be a long floating-point op that eventually traps. Long-latency ops are at highest risk of being passed by a subsequent op. The fdiv. d instr will complete long after the fld f4,0 Ry , for example. The number of cycles that this reordered code takes is Chapter 3 Solutions cycle 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 pipeline 1 Loop: fld f2,0 Rx addi Rx,Rx, 8 fmul. d f2,f6,f2 fdiv. d f8,f2,f0 sub x20,x4,Rx bnz x20,Loop fadd. d f4,f0,f4 fsd f4,0 Ry addi Ry,Ry, 8 Figure S. Fraction of all cycles, counting both pipes, wasted in the reordered code shown in Figure S.

Results of hand-unrolling two iterations of the loop from code shown in Figure S. Every time you see a destination register in the code, substitute the next available T, beginning with T9. Then update all the src source registers accordingly, so that true data dependencies are maintained. Show the resulting code. Hint: see Figure 3. Look at the next two instructions I0 and I1 : I0 targets the F1 register, and I1 will write the F4 register. This means that in clock cycle N, the rename table will have had its cycle 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 pipeline 1 Loop: fld f2,0 Rx fld f12,8 Rx addi Rx,Rx, 16 fmul. d f2,f6,f2 fmul. d f12,f6,f12 fdiv. d f8,f2,f0 fdiv. d f18,f12,f0 sub x20,x4,Rx bnz x20,Loop fadd. d f20,f18,f12 pipeline 2 fld f4,0 Ry fld f14,8 Ry fadd.

I0 gets renamed first, so it gets the first T reg 9. I1 then gets renamed to T In clock cycle N, instructions I2 and I3 come along; I2 will overwrite F6, and I3 will write F0. The convention is that an instruction does not enter the execution phase until all of its operands are ready. So, the first instruction, ld x1,0 x0 , marches through its first three stages F, D, E but that M stage that comes next requires the usual cycle plus two more for latency.

Until the data from a ld is available at the execution unit, any subsequent instructions especially that addi x1,x1, 1, which depends on the 2nd ld cannot enter the E stage, and must therefore stall at the D stage. Four cycles lost to branch overhead. What could go wrong with this? If an interrupt is taken between clock cycles 1 and 4, then the results of the LW at cycle 2 will end up in R1, instead of the LW at cycle 1. Bank stalls and ECC stalls will cause the same effect—pipes will drain, and the last writer wins, a classic WAW hazard. A dynamic branch predictor remembers that when the branch instruction was fetched in the past, it eventually turned out to be a branch, and this branch was taken.

If not, we have some cleaning up to do. The number of clock cycles taken by the code sequence is See Figures S. The bold instructions are those instructions that are present in the RS, and ready for dispatch. Bypassing would save 1 cycle from latency of each, so 4 cycles total. Cutting longest latency in half: divider is longest at 12 cycles. This would save 6 cycles total. Chapter 3 Solutions fld fdiv. d fmul. d f2,0 Rx f8,f2,f0 f2,f8,f2 fld F4,0 Ry fadd. d fadd.
