Transmission rates for two communication schemes: ping/pong and ring transfer have been measured on multiprocessors and clusters of workstations. Performance of a network of computers as a tool for numerically intensive computing has been evaluated on the basis of SLALOM and EP-NAS parallel benchmarks.
In this paper we present a new parallel algorithm for solving traveling salesman problem (TSP). Our algorithm is based on a local optimization method and it was implemented on networked workstations using PVM. The obtained efficiency is 70% on 6 × SUN SPARCstation IPX. It is shown that networked workstations can be efficiently used for solving TSP problem.
Mycotoxins are toxic secondary metabolites produced by fungi. Those biologically active compounds occur naturally and they include zearalenone (ZEN), a mycotoxin that contaminates plant material, including the ingredients used in the production of commercial dog food. The influence of monotonic, low-dose and long-term exposure to ZEN on pre-pubertal bitches has not been fully explored to date. This...
