We build an analytical model for an application utilizing master-slave paradigm. In the model, only three architecture parameters are used: latency, bandwidth and flop rate. Instead of using the vendor supplied or experimentally determined values, these parameters are estimated using the analytical model itself. Experimental results on Cray T3E and SGI Origin 2000 indicate that this simple mode...

Due to the increasing demand for mobility in the area of distributed systems, the use of wireless communication gains in importance. We present a wireless real-time communication protocol for the interconnection of several possibly mobile fieldbus clusters. The protocol is based on the time-triggered paradigm. A single dedicated master node is used to keep the clocks of all slaves synchronized,...

It is well-known that the time and memory necessary to create a codebook from large training databases have hindered the vector quantization based systems for real applications. To overcome this problem, we present a parallel approach for the K-means Vector Quantization (VQ) algorithm based on master/slave paradigm and lowcost parallel cluster computing. Distributing the training samples over t...

This paper introduces the APHID (Asynchronous Parallel Hierarchical Iterative Deepening) game-tree search algorithm. An APHID search is controlled by a master and a series of slave processors. The master searches the rst d 0 ply of the game-tree repeatedly. The slaves are responsible for the bottom plies of the game-tree. The slaves asynchronously read work lists from the master and return scor...

The reallocation of property rights at the transition from slavery to free labor in Brazil, the US South, Jamaica, among others, was followed in most cases by a sharp fall in GDP per capita. One theory for the higher productivity of slaves claims it was the coercion available to slave-owners and not to employers. A second argues that plantations were using various incentives – more food, time o...

Evidence on adverse selection in slave markets remains inconclusive. A necessary prerequisite is that buyers and sellers have different information. We study informational asymmetry on the slave markets through notarial acts on public slave auctions in Mauritius between 1825 and 1835, involving 4,286 slaves. In addition to slave characteristics, the acts document the identities of buyers and se...
