In the area of network monitoring a lot of tools are already available to measure a variety of metrics. However, these tools are often limited to a single administrative domain so that no established methodology for the monitoring of network connections spanning over multiple domains currently exists. In addition , these tools only monitor the network from(More)
In this work we present the Internet Backplane Protocol (IBP), a middleware created to allow the sharing of storage resources, implemented as part of the network fabric. IBP allows an application to control intermediate data staging operations explicitly. As IBP follows a very simple philosophy, very similar to the Internet Protocol, and the resulting(More)
The Internet backplane protocol, or IBP, supports logistical networking to allow applications to control the movement and storage of data between nodes. T o ensure a robust and scalable network, early designers of the Internet chose a stateless model: Routers transfer data statelessly, and routing algorithms, which require only that the routers behave(More)
This paper describes a new technique in the Network Weather Service for producing multi-variate forecasts. The new technique uses the NWS's univariate forecasters and emprically gathered Cumulative Distribution Functions (CDFs) to make predictions from correlated measurement streams. Experimental results are shown in which throughput is predicted for long(More)
This paper presents program transformations directed toward improving communication-computation overlap in parallel programs that use MPI's collective operations. Our transformations target a wide variety of applications focusing on scientific codes with computation loops that exhibit limited dependence among iterations. We include guidance for developers(More)
—Data set sizes are growing exponentially, so it is important to use data movement protocols that are the most efficient available. Most data movement tools today rely on TCP over sockets, which limits flows to around 20Gbps on today's hardware. RDMA over Converged Ethernet (RoCE) is a promising new technology for high-performance network data movement with(More)
Grid and distributed computing environments are evolving rapidly and driving the development of system and network technologies. The design of applications has placed an increased emphasis upon adapting application behavior based on the performance of the network. In addition, network operators and network researchers are naturally interested in gathering(More)
