key insights ˽ A new breed of low-latency I/O devices, ranging from faster datacenter networking to emerging non-volatile memories and accelerators, motivates greater interest in microsecond-scale latencies. ˽ Existing system optimizations targeting nanosecond-and millisecond-scale events are inadequate for events in the microsecond range. ˽ New techniques are needed to enable simple programs to achieve high performance when microsecond-scale latencies are involved, including new microarchitecture support. Watch the authors discuss their work in this exclusive Communications video. http://cacm.acm.org/videos/theattack-of-the-killer-microseconds
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
