Dear Frederick,<br /><br />The devel version has finally been installed in my computer center and optimized for the architecture. I have tested the wisdom file generated via fftw-wisdom and found it to be functioning without any issues (just for estimate planning). For the time being, I believe this is the most effective approach, as it offers a performance boost. Please let me know the progress of the new release and about its compatibility with other types of plans in the wisdom file.<br /><br />Thank you for the support, <br />Best,<br /><br />Santiago Movilla<br /><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Thursday, June 20, 2024 at 9:25:41 PM UTC+2 Frederick Stein wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div>Dear Santiago,</div><div>Regarding the version: There will be a new version in 1-2 weeks if that is more suitable for your compute center.<br></div><div>I have just tried.
