Dear ET folks,
We have made our fast spectral interpolation routine for the TwoPunctures code publicly available. Using this routine you can speed up the initial data generation process of the TwoPunctures code by a factor of ~100, thereby allowing the use of very high spectral resolutions (we have used 50x70^2 or 60x80^2 basis functions in our calculations). As the TwoPunctures code is used outside the ET community as well, we have posted a note announcing the new routine on the arXiv (arXiv:1304.0457http://arxiv.org/abs/1304.0457 ).
Our arXiv note contains a brief description of the routine, a demonstration of its high performance and accuracy, as well as a set of detailed instructions for installing this routine in the standalone TwoPunctures code as well as the ET thorn.
To download a file containing our routines implementing the fast interpolation, visit the following website:

We hope that this new routine will be useful to the ET community.
Best regards,
Vasileios Paschalidis Zachariah Etienne Roman Gold Stuart Shapiro

Dear Vasileios et al
I am sure this will find interest within the ET community. In order to be of most use however, it would be best to integrate your changes into the official TwoPunctures thorn directly.
Would you be interested to prepare a patch (against the development version of TwoPunctures) and would you also be willing to maintain this part of the code - which means to fix bugs should there be some, to respond to questions about it and in general to fell responsible for it?
The recommended way to start this would be to open a ticket at https://trac.einsteintoolkit.org/wiki , pointing to the arXiv note as description (no need to describe everything all over again) and to attach the patch there.

Thanks very much for this; I think it will be extremely useful! What SVN revision was your version developed against? Has it been updated to the current trunk?
