Hello,

It still looks like the Vectors Thorn is required to Carpet to work. Is there a way to not compile this Thorn and still have Carpet work?

Hello David,

I doubt it will work with vectorization since we do not implement
vectors with 16 byte floating point values.

You can try setting

VECTORISE=no

in your option list to disable vectorization which may work.

You can find the available options (not documented unfortunately) here:

Hello,

Has anyone successfully compiled Cactus with REAL_PRECISION = 16?  I get the following error which seems to involve the Vectors Thorn which is required for Carpet.
