Addition Parallel Algorithm
This algorithm is memory optimal however. It is based on the principle of performing arithmetic addition as humans perform addition in the decimal system using a pencil and a paper.

A fast optimal parallel algorithm for a short addition chain Abstract.

Addition parallel algorithm. The Proposed Parallel AlgorithmThe parallel algorithm proposed in this paper is a multithreaded parallel algorithm designed to be executed over multi-processor shared memory architecture. Parallel algorithms for prefix sums can often be generalized to other scan operations on associative binary operations and they can also be computed efficiently on modern parallel hardware such as a GPU. Must be possible the exact distribution to the total amount of data into the available cores.
Do ynexti yi ynexti and then nexti nextnexti until nexti NIL OlgN the Euler-tour technique. That is we need it to be the case that regardless of the values of x y and z x y z x y z. The parallel algorithm is work optimal if W n O T n It is work-time-optimal if Tpar n cannot be improved.
Given a natural number e an addition chain for e is a finite sequence of numbers having the following. The rst construct is a parallel loop indicated with parFor. It is known that if the query is free-connex1 then the maximum intermediate join size is OOUT3 15.
OlgN EREW algorithm to compute the depth of. The idea of building in hardware a functional unit dedicated to computing multi-parameter prefix-sum was patented by Uzi Vishkin.

9 A work-optimal algorithm for adding n numbers Step 1. Once we can compute all the carry bits we can complete the computation to nd the output bits s i easily from a i b i and c i-1. To perform binary addition quickly y n x 1 x 2.
Given a natural number e an addition chain AC for e is a finite sequence of numbers having three. Furthermore even on a single-processor computer the parallelism in an algorithm can be exploited by using multiple functional units pipelined func-tional units or pipelined memory systems. The so-called parallelogram law gives the rule for vector addition of two or more vectors.
The number of cores used must be a exact square root. Addition of two constructs for expressing parallelism. A parallel algorithm can be executed simultaneously on many different processing devices and then combined together to get the correct result.
The running time of this algorithm after dangling tuples have been removed is proportional to the largest intermediate join size Re Z Re. We can substitute for addition in our above parallel-sum algorithm as long as is associative. The parallel time is approximately.
R2BC this algorithm just computes the join R R1ABZ R2BCand then does the aggregation B R. Use only nlog n processors and. Analyze speedup achieved by the parallel algorithm when increases the size of the input data and the number of cores of the architecture.
8 A simple parallel algorithm Adding n numbers in parallel 9. For example the following loop applies a function f to each element of an array A writing the result into an array B. Parallel algorithms are highly useful in processing huge volumes of data in quick time.
For example on a parallel computer the operations in a parallel algorithm can be per-formed simultaneously by different processors. X n parallel EREW prefix algorithm. T shiftCompute t c n3 p32 2t s t w n 2p Matrix-Matrix Multiplication.
When were using our parallel sum algorithm with a generic associative operator we call it a parallel scan. Vector addition is the operation of adding two or more vectors together into a vector sum. The cost-efficiency and isoefficiency of the algorithm are identical to the first algorithm although with larger factors on communication time.
This tutorial provides an introduction to the. For two vectors A and B the vector sum AB is obtained by placing them head to tail and drawing the vector from the free tail to the free head. Cannons Algorithm T align 2t s t w n 2p T P n3 p 2pt s 2t w n2.
Parallel Algorithms As more computers have incorporated some form of parallelism the emphasis in algorithm design has shifted from sequential algorithms to parallel algorithms ie algorithms in which multiple operations are performed simultaneously. A Parallel Addition AlgorithmCarry-Look Ahead. The only problematic part in the above process was the preparation of the carry bits.
