As against the conventional send/receive model, the one-way communication is a new paradigm which decouples message transmission and synchronization. This opens up new opportunities not only to further optimize communication but also to minimize synchronization costs. In this paper, we present a generalized technique which makes use of global dataflow framework to optimize communication and syn...

In contrast to the conventional send/receive model, the one-way communication model—using Put and Synch—allows the decoupling of message transmission from synchronization. This opens up new opportunities not only to further optimize communication but also to reduce synchronization overhead. In this paper, we present a general technique which uses a global dataflow framework to optimize communic...

This paper proposes an architecture that can optimize inter-VM communication in an NFV environment through the creation of direct channels between virtual machines. Particularly, our prototype can transparently optimize the data transfer between virtual machines running DPDK applications by dynamically recognizing the existence of pointto-point connections in the traffic steering rules, reverti...

Financial engineering and electrical engineering are seemingly different areas that share strong underlying connections. Both areas rely on statistical analysis and modeling of systems; either modeling the financial markets or modeling, say, wireless communication channels. Having a model of reality allows us to make predictions and to optimize the strategies. It is as important to optimize our...

Many large distributed system are characterized by having a large number of components (eg., agents, neurons) whose actions and interactions determine a %orld utility” which rates the performance of the overall system. Such “collectives” are often subject to communication restrictions, making it difiicult for components which tzy to optimize their own “private” utilities, to take actions that a...

In all massively parallel systems (MPPs), whether message-passing or shared-address space, the memory is physically distributed for scalability and the latency of accessing remote data is orders of magnitude higher than the processor cycle time. Therefore, the programmer/compiler must not only identify parallelism but also specify the distribution of data among the processor memories in order t...
