Reliable communications in FTL
نویسنده
چکیده
Local-area networks based on high-bandwidth packet-switching technology, such as ATM, show a tremendous promise in reducing communication latencies and overheads. However, the lack of ow-control and reliable delivery in ATM networks requires the higher protocol layers to deal with cell loss or corruption. While it is possible to use TCP-based communications over ATM, the protocol mismatch results in a signi cant loss of the bandwidth. In addition to this, there is also a signi cant mismatch between the stream-based communication model provided by TCP, and the message-oriented communication model required by the parallel applications. This paper describes the design and implementation of a reliable messaging layer aimed at workstation clusters using broadcast and packet-switched local area networks.

Generative frameworks for rigorous model-driven development
Our increasing reliance on software systems requires reliable software. Mainstream software manufacture, however, is not rigorous and precise, and resulting software lacks the desired reliability. Formal methods take a rigorous and precise approach to software development, delivering reliable software, but they are widely recognised as being impractical. Although the situation is improving, the...
متن کاملDefinition of Flexible Transfer Line with Rework Paths and Its Simulator for Optimal Production Design
The buffer size decision for the flexible transfer line (FTL) gains more and more importance because of growing FTL complexity. The buffer size in front of the bay of machines in the FTL is still one of the major optimization problems faced by production engineers. In this paper, we attempt to find the near optimal design of buffer size for flexible transfer line with rework paths (FTL-RP) that...
متن کاملAnalysis of Modified Feed-Through Logic with Improved Power Delay Product
A modified approach for Feed-Through logic (FTL) is developed in this paper to provide improved power delay product (PDP). FTL is examined against proposed approach, by analysis through computer simulation. It is shown that the modified FTL has low power consumption and high speed over existing FTL. Based on the performance the given approach is found very efficient for high speed arithmetic or...
متن کاملA Scalable and Highly Configurable Cache-Aware Hybrid Flash Translation Layer
This paper presents a cache-aware configurable hybrid flash translation layer (FTL), named CACH-FTL. It was designed based on the observation that most state-of-the-art flash-specific cache systems above FTLs flush groups of pages belonging to the same data block. CACH-FTL relies on this characteristic to optimize flash write operations placement, as large groups of pages are flushed to a block...
متن کاملFaster than light motion does not imply time travel
Seeing the many examples in the literature of causality violations based on faster-than-light (FTL) signals one naturally thinks that FTL motion leads inevitably to the possibility of time travel. We show that this logical inference is invalid by demonstrating a model, based on (3+1)-dimensional Minkowski spacetime, in which FTL motion is permitted (in every direction without any limitation on ...
