Swim: A Runtime for Distributed Event-Driven Applications [article]

Chris Sachs, Ajay Govindarajan, Simon Crosby
2022 arXiv   pre-print
Streaming actors are vertices in the dataflow graph that concurrently analyze new events and modify their states. A link is an edge in the graph and is a URI binding to an actor's streaming API.  ...  Swim builds a running application from streaming events, creating a distributed dataflow graph of linked, stateful, concurrent streaming actors that is overlaid on a mesh of runtime instances.  ...  Streaming actors compute on new events whenever their inputs change. • Swim streams every actor state change over each of its links to other actors, for use in their analysis.  ...

Timing local streams

Huaiyu Zhu, Yong Chen, Xian-He Sun
2010 Proceedings of the 24th ACM International Conference on Supercomputing - ICS '10  
Based on the proposed stream timing technique, we extend the conventional stride prefetcher and propose a new stride prefetcher called Time-Aware Stride (TAS) prefetcher.  ...  However, the existing stream localization technique lacks the timing information of misses.  ...  However, MLS only issues one prefetch for each stream and always attempts to traverse the stream chain to find new streams.  ...
