@muhammadmuneeb21187 жыл бұрын
A key factor in determining the cost of an integrated circuit is volume. Which of the following are reasons why a chip made in high volume should cost less? 1. With high volumes, the manufacturing process can be tuned to a particular design, increasing the yield. 2. It is less work to design a high-volume part than a low-volume part. 3. Te masks used to make the chip are expensive, so the cost per chip is lower for higher volumes. 4. Engineering development costs are high and largely independent of volume; thus, the development cost per die is lower with high-volume parts. 5. High-volume parts usually have smaller die sizes than low-volume parts and therefore have higher yield per wafer

Great explanation, Prof. i'm through 54m into this video, i think using separate row-buffers for each core would solve this issue. Like we do with servers, having multiple cache servers, replica of main servers for data access. Like wise, instead of mutli-cores with one DRAM and single row-buffer, keep the multi-cores with one DRAM but same number of row-buffers as cores. The OS scheduler will do the rest.

I have a question regarding cell variation in retention, what causes some cells to (reliably) leak faster than others?
@CMUCompArch9 жыл бұрын
colloredbrothers This is due to process variation effects. Cells are of different size and strength as manufacturing is imperfect. Simplifying a bit: Some cells can inherently store less charge than others (due to a small capacitor size) and some cells are inherently more prone to leaking faster (due to a weak transistor). A combination of less charge (small capacitor) and fast leakage (leaky transistor) leads to a fast-leaking cell. For more, see references [8, 21, 25] here: users.ece.cmu.edu/~omutlu/pub/raidr-dram-refresh_isca12.pdf and take a look at this paper that explains the charge storage and its effects on latency: users.ece.cmu.edu/~omutlu/pub/adaptive-latency-dram_hpca15.pdf

@gokulsubramanianravi18929 жыл бұрын
+Carnegie Mellon Computer Architecture Wouldn't the access pattern (of the DRAM) influence the need for refresh more than PVT variations? Say a particular row is constantly written to - this row would not need regular stand-alone refreshes since the write action itself inherently refreshes data. I can think of similar analogies for read actions as well, influencing how regularly refreshing is needed for a particular row that is constantly read from. But I do believe that exploiting PVT variations can cause significant gains since I think memory is designed with a significantly larger guardband in comparison to logic thereby allowing more room for adaptively cutting into the guardband and extracting better energy/performance.
@CMUCompArch9 жыл бұрын
+Gokul Subramanian "More than" is very debatable. However, access pattern of course affects the need for refreshing a row. The example you gave for reads and writes makes sense. In fact, take a look at this "Smart Refresh" paper that proposes to exploit the fact that a recently accessed row does not need to be refreshed: dl.acm.org/citation.cfm?id=1331714. Usually, techniques to eliminate refreshes of recently accessed rows comes at a high hardware overhead needed to keep track of recently accessed rows, however, as explained in Section 4.2 here: users.ece.cmu.edu/~omutlu/pub/raidr-dram-refresh_isca12.pdf.
@CMUCompArch9 жыл бұрын
+Gokul Subramanian You are right that there is a large guardband in refresh and timing. Current DRAM refresh and timing parameters are set to ensure correct operation in worst-case devices and operating conditions. Exploiting the retention time and access latency heterogeneity of different rows and operating conditions can greatly improve the performance and power consumption of modern memories. I would recommend anyone interested in this topic (retention time and timing variations in modern DRAM) to read the following papers. "RAIDR: Retention-Aware Intelligent DRAM Refresh" users.ece.cmu.edu/~omutlu/pub/raidr-dram-refresh_isca12.pdf "An Experimental Study of Data Retention Behavior in Modern DRAM Devices: Implications for Retention Time Profiling Mechanisms" users.ece.cmu.edu/~omutlu/pub/dram-retention-time-characterization_isca13.pdf "Adaptive-Latency DRAM: Optimizing DRAM Timing for the Common-Case" users.ece.cmu.edu/~omutlu/pub/adaptive-latency-dram_hpca15.pdf You can find the presentations of these papers at users.ece.cmu.edu/~omutlu/projects.htm.

Memory Hog Problem (Solution, my thoughts): Considering the bottleneck is memory controller and I see the primary reason is the fetch logic is predefined and hard to control as a static parameter. What if we abstract the functions of the memory controller and leave them as API's to be implemented on the system software layer. What I mean is suppose we if we have an interface to implement scheduling logic, we can actually implement the memory access logic on the device driver of the controller and have the device point to this logic. This makes it more generic.
