Finch: Domain Specific Language and Code Generation for Finite Element and Finite Volume in Julia
AbstractWe introduce Finch, a Julia-based domain specific language (DSL) for solving partial differential equations in a discretization agnostic way, currently including finite element and finite volume methods. A key focus is code generation for various ...

Consistency Fences for Partial Order Delivery to Reduce Latency
Computational Science – ICCS 2022Jun 2022, Pages 488–501https://doi.org/10.1007/978-3-031-08751-6_35AbstractFor appropriate workloads, partially ordered message delivery can greatly reduce message latency. For example, updates to screens (e.g., remote desktops, VNC) may not have to be totally ordered with respect to different regions of the screen, but ...
