Please have a look at:


which you can clone as

git clone https://rhaas80@bitbucket.org/rhaas80/twopuncturescigr.git

to see if this contains something you find useful. It is *not* a branch
based of the currrent TwoPunctures (it is based of an older version) so
may for example contain bugs (there is one to do with the phi component
that was fixed in current master but likely not in this repository).

It does however offer code for checkpointing/recovering the spectral
data as well as support for OpenMP in TwoPunctures itself (this may also
already be in master).


My email is as private as my paper mail. I therefore support encrypting
