Clusters of multiprocessors, or Clumps, promise to be the supercomputers of the future, but obtaining high performance on these architectures requires an understanding of interactions between the multiple levels of interconnection. In this paper, we present the rst multi-protocol implementation of a lightweight message layer|a version of Active Messages-II running on a cluster of Sun Enterprise...

BACKGROUND The healing of xenograft augmentated intra-alveolar gaps following immediate implant placement (IMIP) after tooth extraction is likely to differ in time and density compared to the native bone part that directly contacts the implant. MATERIAL AND METHODS Secondary implant stability (SIS) data recorded 2-3 months following a late implant placement protocol (LIP) (n= 43) and 6-8 mont...

We are proposing Z Network Protocol (ZNP) as a network layer protocol based on ID/Locator split approach in the future Internet. ZNP is designed to satisfy the following requirements in terms of practical operation: (1) support of L3 protocol heterogeneity, (2) scalability of ID/Locator mapping system, (3) independence of mapping information management, and (4) avoidance of locator leakage beyo...

Wireless Communication, one of the important demanding technologies basically suffers from unreliable nature due to its high bit error rate caused by handoffs. Transmission Control Protocol, the reliable successful Transport Protocol, basically designed for a wired network handles network congestion effectively. When TCP is implemented over Wireless Network, there will be significant loss due t...

A “Storage-Area Network” (SAN) comprises computers (“Initiators”), storage “block devices” (“Targets”), and a Controller(s). Most SANs use the SCSI protocol over various communication infrastructures. Presently, all Initiator Target traffic must pass through the Controller, severely limiting scalability. We extend the SCSI-3 Transport layer to support distribution, and combine this with SCSI's ...

The paper proposes a measurement on-demand (MoD) service over Internet, which allows accessing, streaming and delivery of archived process acquisition data. A client accesses to the service for the purpose of receiving previously stored process acquisition data under the form of media streams. Media streams are captured, on the receiver site, by using multimedia-based Distributed Virtual Instru...

ARTCP is a transport level communication protocol based on TCP. It uses temporal characteristics of data flow to control it, that allows to split algorithms of congestion avoidance and reliable delivery. The article discusses possible ARTCP header structure and practical aspects of forming the header and calculation of the header fields. It demonstrates the possibility of transparent replacemen...
