COMP 633: Parallel Computing PRAM Algorithms

In computer science, a parallel random-access machine (parallel RAM or PRAM) is a shared-memory abstract machine. As its name indicates, the PRAM is intended as the parallel-computing analogy to the random-access machine (RAM) (not to be confused with random-access memory). In the same way that the RAM is used by sequential-algorithm designers to model algorithmic performance (such as time complexity), the PRAM is used by parallel-algorithm designers to mo… Webthis algorithm is correct for sync/async systems and message and time complexities are same. for p i. 1 2. upon receiving no message: terminate. for p j, 0 ≤ j ≤ n − 1, j ≠ i. 1 2 3. … WebPRAM Algorithms Sums ...

WebThe PRAM model is a widely used theoretical model for parallel algorithm design which has been studied for several decades, resulting in a rich framework for parallel discrete and combinatorial algorithms including many parallel graph algorithms (see e.g. []).A PRAM is defined as a collection of synchronous processors executing in parallel on a single … Weblifetime of PRAM of the baseline and system with CA-SW is shown in Fig. 5. With the parameter a =1, our algorithm achieves a lifetime extension of 57% on average over the baseline. With a=2, more 4% lifetime improvement is achieved. We can say that with bit-level wear-leveling mechanisms, our CA-SW algorithm is effective in extending the ...

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. cadeau windsurfWebWe have seen examples of PRAM algorithms which are not cost optimal.
