That would certainly be nice, but it would require quite a lot of
thought.
As things stand (if I understand the mechanism correctly) you have
to specify at compile time which code sections are to be
parallelized via openmp. In principle it's possible that gretl
could call a C compiler to build a gretl-loop as a C function with
user-specified parallel code -- a sort of "instant plugin". That
functionality would necessarily be limited to platforms that offer
an openmp-aware C compiler, preferably gcc. It would also require
more knowledge than I currently possess regarding "Just in Time"
compilation ;-)
