It Takes Two : Instrumenting the Interaction between In-Memory Databases and Solid-State Drives

Lerner, Alberto ; Kwak, Jaewook ; Lee, Sangjin ; Park, Kibin ; Song, Yong Ho ; Cudré-Mauroux, Philippe

In: CIDR 2020, 10th Conference on Innovative Data Systems Research, Amsterdam, The Netherlands, January 12-15, 2020, Online Proceedings, 2020, p. 1-8

In-memory databases rely on non-volatile storage devices for services such as durability and recovery. SSDs can provide the high-performance these services require. When performance problems occur, however, SSDs offer no mechanism to help analyze them. The only alternative is to instrument the database side of the problem and conjecture about what might be the cause of performance...

Networking and Storage : The Next Computing Elements in Exascale Systems?

Lerner, Alberto ; Hussein, Rana ; Ryser, André ; Lee, Sangjin ; Cudré-Mauroux, Philippe

In: IEEE Data Engineering Bulletin, 2020, vol. 43, no. 1, p. 60-71

Many large computer clusters offer alternative computing elements in addition to general-purpose CPUs. GPU and FPGAs are very common choices. Two emerging technologies can further widen the options in that context: in-network computing (INC) and near-storage processing (NSP). These technologies support computing over data that is in transit between nodes or inside the storage stack,...
