PIM - processing in memory?
I don't think this is something that actually exists in a working competitive state. I also don't think there is "more attention" by anyone actually working on cpus.
You don’t burn active power?
What does this mean?
- gdiamos 2y agoSSDs are 3D with high stacking. They retain data without burning power, unlike SRAM. What if you put some of these 3D transistors tightly integrated with a 3D SSD and power gated them? It seems like you would beat the memory wall. Obviously manufacturing that is beyond us today.
- CyberDildonics 2y agoIt seems like you would beat the memory wall. I don't know what this is supposed to mean. Why would putting coprocessing somewhere outside of the CPU be better than just sending data to storage?
- gdiamos 2y agoIt takes a lot of energy to move data
- CyberDildonics 2y agoSays who? Also wouldn't this idea just be moving data before it's fully processed? Why wouldn't the intermediate data be bigger? Also "a lot" isn't a number and what are you comparing it to?
- gdiamos 2y agoSays the hotchips keynote - https://www.youtube.com/watch?v=rsxCZAE8QNA&t=2480s https://www.youtube.com/watch?v=rsxCZAE8QNA&t=2480s - data that is moved is about 100x higher power than data that is local You have a good point about intermediate data. This would not apply to all algorithms.
- CyberDildonics 2y agoYou're talking about processing data, then moving data and processing it somewhere else, which is the opposite of the locality that presentation is saying valuable.
