Large-scale IT services are now increasingly run in memory due to tight application latency demands. With services centered mostly around data, datacenter owners often integrate as much DRAM into a single blade as technology allows, and use low-latency high-bandwidth network fabrics to aggregate near-neighbor DRAM into large memory pools. DRAM accounts for a substantial fraction of overall server capital and operation costs, and as such designers are increasingly customizing server hardware, software and infrastructure for online services around memory. In this talk, I will first motivate specialized server design for in-memory computing and then present promising avenues to explore specialization to improve server design.
