Machine main performance characteristics

This chapter examines the overaii performance characteristics of compressors and turbines. This materiai is presented here to famiiiarize the reader with the behavior of these machines, ciassified under the broad term tur-bomaciiinery. Pumps and compressors are used to produce pressure turbines produce power. These machines have some common characteristics. The main eiement is a rotor with biades or vanes, and the path of the fluid in the rotor may be axiai, radiai, or a combination of both. 

Smith has also described the implementation of MD on parallel machines, with particular reference to hypercube computers. In work designed to introduce a novice to the main aspects of parallel computing in MD, Smith described three particular algorithms replicated data (RD), systolic loop (SLS-G), and parallelized link cells (PLC), all of which have good load balancing. The performance characteristics of each algorithm and the factors affecting... 

The two machines used for the evaluation have different performance characteristics and different cache size. It is expected that the optimal parameter estimate for both will reflect these differences. Examining the values, for example, for the test case using the Google sparsehash the desktop machine calculates Jumpahead distance as 3,003 and workahead size as 500 while the estimates of the laptop are 500 and 100, respectively (see Table 3.1). The jumpahead distance value, we remind, is the distance between the main thread and the helper thread and...
