All Tomorrow’s Memories (With Apologies to Lou Reed)
TimeTuesday, June 23rd11am - 11:25am
DescriptionMemory and communication are the primary reasons that our time-to-solution is no better than it currently is … the memory system is slow; the communication overhead is high; and yet a significant amount of research is still focused on increasing processor performance, rather than decreasing (the cost of) data movement. I will discuss recent & near-term memory-system technologies including high-bandwidth DRAMs and nonvolatile main memories, as well as the impact of tomorrow’s memory technologies on tomorrow’s applications and operating systems. Modern multicore and manycore designs exacerbate the problem, but two solutions are on the horizon.
