The Impact of Thread-Per-Core Architecture on Application Tail Latency

Pekka Enberg, Ashwin Rao, Sasu Tarkoma
2019 2019 ACM/IEEE Symposium on Architectures for Networking and Communications Systems (ANCS)  
The thread-per-core architecture has emerged to reduce these overheads, but it also has its challenges from thread synchronization and OS interfaces.  ...  We measure the impact of thread-per-core architecture on application tail latency by implementing a key-value store that uses application-level partitioning, and inter-thread messaging and compare its  ...  Arachne is a core-aware, user-level threading library that aims to provide high throughput and low latency for short-lived threads (in the order of few microseconds) [36] .  ...
