Last week, we read “Databases in the Era of Memory-Centric Computing” CIDR’25 paper in our reading group. This paper argues that the rising cost of main memory and lagging improvement in memory bandwidth do not bode well for traditional computing architectures centered around computing devices (i.e., CPUs). As CPUs get more cores, the memory bandwidth available to each core remains flat or even decreases, as shown in the figure below. Similarly, the cost of memory does not decrease as f...
