[Users] What/where is thorn 'DGEMM'?

[Erik Schnetter]

I believe thorn DGEMM is my fault: This is a thorn I wrote at some
point to measure the raw floating point performance of the CPUs in a
simulation, to detect cases where this performance is suddenly much
lower than expected. This thorn is available in the LSUThorns
repository. However, you don't need it -- it should not be activated
in an example parameter file.

I just see that the url <https://svn.cct.lsu.edu/> list all subversion
repositories at the CCT, including DGEMM... but that doesn't help you
run examples.

I'm afraid we don't really have a good set of examples (we should!).
We used to have a few with the first version of the Einstein Toolkit,
but these are by now probably out of date. Your best bet is probably
to ask for a good parameter file e.g. for a binary black hole
collision or a neutron star calculation, and then to simplify/modify
this until it suits your needs.
