Lecture 1. Introduction and Basics - Carnegie Mellon - Computer Architecture 2015 - Onur Mutlu

[@CMUCompArch]

Hello everyone. I hope you are enjoying the lectures. You can find the latest lectures on Computer Architecture (from 2017 to Present) in our new KZbin channel: kzbin.info

[@niedas3426]

Big thank you for making these publicly available. I do study in an unrelated field but I have a background in EE. I still find EE and CS very interesting and I want to understand more than just the fundamentals, so I hope I will enjoy the course :)

[@donaldnjila1137]

Thank you very much for making this available to everyone. I am truly enjoying the lectures and assignments. I intend to slowly go through as many the lectures as possible and document any findings, research results and answers to exercises which I will be glad to share with you if you are willing. Thank you for the excellent work that you do to advance technology for the future.

To have quick free access to such incredible information is truly a miracle.

Information costs next to nothing to duplicate. To *not* have quick free access to valuable information which was already recorded should be a moral outrage. University shareholders and boardmembers are all parasite scum.

Thank you is all I can say. Democratising the acquisition of knowledge and high quality teaching is one of the truly extraordinary things about the internet age. Higher Education institutions who do so, for me, instantly gain my respect and good grace.

Soon that job will be outsourced or you’ll be fired when the project is over. Automation will take away these jobs first. You are not passionate about it why do it? become a lawyer or doctor for money not this.

[@sukantasaha5678]

@@cardcode8345 1) I am passionate about these and that's why I'm learning these outside of school. 2) As someone who is in academia, I can tell you that the only way to stay on top of automation is to know enough so that you can create these automations yourselves. Automating lower level tasks is how CS moves forward. But it takes another CS student to actually create these automations.

[@Peregringlk]

54:00 you could solve the problem by having as many row buffers as cores, right?

[@CMUCompArch]

Potentially, but that solution is not only too expensive (a row buffer is huge), but couples the DRAM chip design (which contains the row buffers) to the number of cores (which is part of the CPU, GPU or accelerators). So, it is not a good solution.

[@Priyanka-hs7gw]

What r the prerequisites for this course

[@muhammadmuneeb2118]

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

[@sangramkesariray]

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.

[@sangramkesariray]

At 1:34:25, how about throttling the DRAM access. It'll definitely reduce the hammerings and shall not meet the access rates for erroring out adjacent memory rows.

[@AhmedDeedatPalestine]

so even if the operating system schedules the two processes to two cores, which is fair because each process gets its own, but bottleneck is the memory access policy.

[@AbhisarMohapatra]

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.
