You mean: being able to pass a mask to the reduce function in Cactus? <br class="">
<br class="">
Would be nice, unfortunately as far as I know, the "old" reduction<br class="">
interface using CCTK_Reduce<br class="">
(<a href="http://einsteintoolkit.org/usersguide/UsersGuidech9.html#verbatim-64" class="">http://einsteintoolkit.org/usersguide/UsersGuidech9.html#verbatim-64</a>)<br class="">
which Carpet uses does not let you pass in a param_table_handle the way<br class="">
that CCTK_ReduceGridArrays<br class="">
(<a href="http://einsteintoolkit.org/referencemanual/ReferenceManualch2.html#x4-165000A2" class="">http://einsteintoolkit.org/referencemanual/ReferenceManualch2.html#x4-165000A2</a>)<br class="">
does.<br class="">
<br class="">
So one would first have to convert Carpet to support the "new"<br class="">
reduction interface (which is probably simple as the differences seem<br class="">
minor to me).<br class="">

<div>I meant to use CarpetMask; isn't this a way to mask points from reductions?</div>
