Responsive Parallelism with Futures and State
[article]
2020
arXiv
pre-print
Preserved Fulltext
Motivated by the increasing shift to multicore computers, recent work has developed language support for responsive parallel applications that mix compute-intensive tasks with latency-sensitive, usually ...
These developments include calculi that allow assigning priorities to threads, type systems that can rule out priority inversions, and accompanying cost models for predicting responsiveness. ...
CONCLUSION This paper bridges cooperative and competitive threading models by bringing together a classic threading construct, futures, with priorities and mutable state. ...

In this paper we extend relative debugging to support porting stencil computation on a hybrid computer. ...
Relative debugging is particularly effective when code is migrated from one platform to another, and this is of significant interest for hybrid computer architectures containing CPUs accelerators or coprocessors ...
To bridge the variety of data partitioning schemes used in practice at different levels of parallelism, we propose a generic data model for general stencil computations on a hybrid computer. ...
