compile4float64: Enable compiling of user-defined operators using float 64bits...

In rkeops: Kernel Operations on GPU or CPU, with Autodiff, without Memory Overflows

Description

Set up rkeops compile options to compile user-defined operators that use float 64bits precision in computation.

Usage

compile4float64()

Details

Note: Default behavior is to compile operators operators that use float 32bits precision in computation. Hence, if you do not modify rkeops options, you have to call the function compile4float64 to compile operators using float 64bits precision.

Using float 64bits (or double) precision is likely to result in a loss of performance regarding computing time on GPU. If you want to get the best performance but worry about computation precision, you can use float 32bits precision and compensated sums that are implemented in KeOps.
