Sentence examples for double-precision accuracy from inspiring English sources
To improve the approximate solution, we introduce an iterative refinement procedure that allows to cheaply recover full double-precision accuracy.
This elegant method takes advantage of the Cauchy-Riemann differential equations for complex derivatives and achieves full double-precision accuracy, thereby avoiding the stepsize dilemma of common finite-differencing formulae (Martins et al. 2003).
We have developed a new mixed precision approach for Krylov solvers using reliable updates which allows for full double precision accuracy while using only single or half precision arithmetic for the bulk of the computation.
Using a pair of floating point numbers double precision accuracy is approximated through single precision floating point operations.
The advantage is that we can easily add additional higher order integrators that require double precision accuracy computations, without having to rewrite major parts of the host code.
By developing operational software which is designed to run on a single CPU, parallelised on multi-core CPUs or massively parallelised on GPUs while retaining double precision accuracy, high-accuracy approaches which would ordinarily not be feasible due to long processing times can be employed routinely.
We perform simulations of Plummer (Plummer 1915) spheres using 1 and 4 GPUs with double-single (DS) and full double precision (DP) accuracy.
We show that a mixed-precision computing model can improve performance compared to a fully double-precision model while still providing good numerical accuracy.
The lack of fast double-precision floating point operations on current graphics hardware limits the accuracy of the reconstructions to some extent.
