Maybe default this to on in the cases where it works? (of course keeping a way to force which is used)
| Could you take a look? This now seems to fail CI. |
| This is because I changed the default for the M2L translation to FFT and now all tests require the additional translation_classes data. How about I keep the default to non FFT in sumpy and use the FFT in pytential where the translation_classes is computed and passed? |
| I'd prefer to have the default at FFT while modifying all the constructor calls in sumpy. I could also live with a non-FFT default that yells about its deprecation. (To be clear: We won't deprecate non-FFT execution, just not specifying which you want.) |
isuruf changed the title | Factor of 2 change fixed the tests. Once inducer/pytential#102 is merged this should be ready for review. |
Out of curiosity: where was that factor of 2? Also, for my peace of mind: There are no functional changes here, correct? |
There's the factor of 2 change in rscale and the change of default for M2L translation type to FFT. |

This was hard to review because of the amount of code that's moved. But pending your confirmation that there are no functional changes and that the factor of 2 is innocuous, this LGTM. Thanks for working on this!
| Didn't see your response until after I submitted the review. Thanks for the summary! LGTM, in it goes. |
