WebIf one PRAM algorithm outperforms another PRAM algorithm, the relative performance is not likely to change substantially when both algorithms are adapted to run on a real parallel computer. The PRAM model. Figure 30.1 shows the basic architecture of the parallel random-access machine (PRAM). There are p ordinary (serial) processors P 0, P 1,. . . WebA PRAM algorithm requiring time T(n), can be simulated in a mesh of tree in time T(n)log2n/loglogn, that is each step can be simulated with a slow-down of log2n/loglogn. Instead of design ad hoc algorithms for bounded degree networks, design more general algorithms for the PRAM model and simulate them on a feasible network.
