HINT is intended to be "scalable" to run on any size computer, from small serial systems to highly parallel supercomputers. [1] The person using the HINT benchmark can use any floating-point or integer type. [2] HINT benchmark results have been published comparing a variety of parallel and uniprocessor systems. [3]
In parallel computing, all-to-all (also known as index operation or total exchange) is a collective operation, where each processor sends an individual message to every other processor. Initially, each processor holds p messages of size m each, and the goal is to exchange the i-th message of processor j with the j-th message of processor i.
Due to the inherent difficulties in full automatic parallelization, several easier approaches exist to get a parallel program in higher quality. One of these is to allow programmers to add "hints" to their programs to guide compiler parallelization, such as HPF for distributed memory systems and OpenMP or OpenHMPP for shared memory systems ...
In numerical linear algebra, the tridiagonal matrix algorithm, also known as the Thomas algorithm (named after Llewellyn Thomas), is a simplified form of Gaussian elimination that can be used to solve tridiagonal systems of equations.
The use of non-parallel axes enabled the non-linear relationships to be incorporated into the model. The numbers in square boxes denote the axes requiring input after appropriate assessment. The pair of nomograms at the top of the image determine the probability of occurrence and the availability, which are then incorporated into the bottom ...
Loop-level parallelism is a form of parallelism in software programming that is concerned with extracting parallel tasks from loops.The opportunity for loop-level parallelism often arises in computing programs where data is stored in random access data structures.

Parareal is a parallel algorithm from numerical analysis and used for the solution of initial value problems. [1] It was introduced in 2001 by Lions, Maday and Turinici.Since then, it has become one of the most widely studied parallel-in-time integration methods.
