Erew pram algorithm
WebAug 28, 2024 · Our parallel algorithm on EREW PRAM consists of four main steps: The first step of the proposed algorithm is initialization. We use n processors to initialize the first element of A with 1 and the next n-1 elements of A with 2. The second main step is computing the addition chain for 2^ {n-1}. WebObviously, EREW PRAM is constrained in the same way as an 1-port network. In the first step, the source writes the data into a shared memory cell. The standard optimal algorithm then just doublesthe number of copies of the data in the shared memory in every step, as implied by Figure . As a result, the number of informed processors doubles, too.
