第六届超级计算机运行和操作系统国际研讨会（6th International Workshop on Runtime and Operating Systems for Supercomputers）(ROSS)
第六届 超级计算机运行和操作系统 研讨会
2017/6/21
The complexity of node architectures in supercomputers increases as we cross petaflop milestones on the way towards Exascale. Increasing levels of parallelism in multi- and many-core chips and emergin...
A Portable Runtime Interface For Multi-Level Memory Hierarchies
Memory Hierarchies Parallelism Runtime Sequoia
2016/5/24
We present a platform independent runtime interface for moving data and computation through parallel machines with multi-level memory hierarchies. We show that this interface can be used as a compiler...
First-class Runtime Generation of High-performance Types using Exotypes
First-class Runtime Generation High-performance Types Exotypes
2016/5/24
We introduce exotypes, user-defined types that combine the flexibility of meta-object protocols in dynamically-typed languages with the performance control of low-level languages. Like objects in dyna...
Realm: An Event-Based Low-Level Runtime for Distributed Memory Architectures
Realm Legion distributed memory deferred execution events reservations heterogeneous architectures runtime
2016/5/24
We present Realm, an event-based runtime system for heterogeneous,distributed memory machines. Realm is fully asynchronous: all runtime actions are non-blocking. Realm supports spawning computations, ...
Automatic and Transparent I/O Optimization With Storage Integrated Application Runtime Support
Automatic Transparent I/O Optimization Storage Integrated Application Runtime Support
2016/5/24
Traditionally storage has not been part of a programming model’s semantics and is added only as an I/O library interface.
Analysis of Application Sensitivity to System Performance Variability in a Dynamic Task Based Runtime
Application Sensitivity System Performance Variability Dynamic Task Based Runtime
2016/5/24
Application scalability can be significantly impacted by node level performance variability in HPC. While previous studies have demonstrated the impact of one source of variability,OS noise, in messag...
