Parallelization of an Adaptive Mesh Refinement Method for Low
An algorithm is a sequence of steps that take inputs from the user and after some computation, produces an output. A parallel algorithm is an algorithm that can execute several instructions simultaneously on different processing devices and then combine all the individual outputs to produce the final result.
In this article, we encompass an analysis of the recent advances in parallel genetic algorithms (pgas).
Because blind deconvolution algorithms are iterative in nature, they can take minutes to days to deblur an image depending how many frames of data are used for the deblurring and the platforms on which the algorithms are executed. Here we present our progress in parallelizing a blind deconvolution algorithm to increase its execution speed.
Googlenet is a type of convolutional neural network based on the inception architecture. It utilises inception modules, which allow the network to choose between multiple convolutional filter sizes in each block. An inception network stacks these modules on top of each other, with occasional max-pooling layers with stride 2 to halve the resolution of the grid.
We present experimental results for parallelizing two breadth-first search-based applications on thinking machines cm-5 by using two different message-passing paradigms, one based onsend/receive and the other based onactive messages. The parallelization of these applications requires fine-grained communication. Our results show that the active messages-based implementation gives significant.

A sequential algorithm for computing the bi-dimensional fourier transform (denoted ft), consists of computing a mono-dimensional ft (using a classical fft algorithm) on rows and then on columns of a matrix. We have implemented a bi-dimensional fft called the transpose split (denoted ts) algorithm [10,5].

The algorithm used to partition the graph is the inertial flow [schild and sommer, 2015], a recursive algorithm that cuts a set of nodes in two subsets by computing the min-cut, with a flow algorithm, and then the same method is called for each subset. The stopping conditions are either a maximum depth or a minimum size of nodes in a subset.

Turns out this algorithm has parallelism of n/lg 2 (n), that is much better.

Ered the same algorithm in the context of routing wires on circuit boards. A variety of parallel bfs algorithms have since been ex-plored [3,9,21,25,31,32]. Some of these parallel algorithms are work efficient meaning that the total number of operations per-formed is the same to within a constant factor as that of a com-parable serial algorithm.

We demonstrate our approach on several important cache-oblivious algorithms, including longest common sub-sequence (lcs), classic rectangular matrix multiplication (mm), strassen's algorithm, and comparison-based sorting. By our approach, we provide an almost exact solution to the open problem on parallelizing strassen.
Many machine learning algorithms are easy to parallelize in theory. However, the xed cost of creating a distributed system that organizes and manages the work is an obstacle to parallelizing existing algorithms and prototyping new ones. We present qjam, a python library that transpar-ently parallelizes machine learning algorithms that adhere.
In computer science, a parallel algorithm, as opposed to a traditional serial algorithm, is an algorithm which can do multiple operations in a given time. It has been a tradition of computer science to describe serial algorithms in abstract machine models, often the one known as random-access machine.

The recursive nature of the blocked algorithm also led to the notion of “cache-oblivious” algorithms, in which the recursive subdivision produces successively smaller subproblems that eventually fit into a cache or other fast memory layer. 10 whereas other blocked algorithms are implemented to match the size of a cache, the oblivious.
