Sentence examples for double precision accuracy from inspiring English sources

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.

This standalone code contains a sixth order integrator, and supports CUDA, OpenCL and IEEE-754 double precision accuracy.

Using a pair of floating point numbers double precision accuracy is approximated through single precision floating point operations.

The code runs on a range of NVIDIA and AMD GPUs in single and double precision accuracy.

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.

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 perform simulations of Plummer (Plummer 1915) spheres using 1 and 4 GPUs with double-single (DS) and full double precision (DP) accuracy.

The exact blend of single and double precision varies depending on the required accuracy as discussed earlier, for a typical step more than 90% of the flops are calculated on the GPU, and almost 40% of those are in double precision.

For those applications where the accuracy is essential, the double precision is still required.
