How hard work it be to actually add CVODE and its numerical integrators
to those already available in pcenv through the GSL? Not some special
version of it coded up in Auckland, but CVODE itself as distributed from
SUNDIALS.
Seems to me that pcenv is using a whole bunch of new technology that no
one else currently uses in their tools - CORBA, XUL/mozilla,
cellml_corba_server. So in order to get a better understanding of the
performance of pcenv it would be a good idea to make everything as
"standard" as possible. Then the actual integration can be taken out of
the equation when comparing performance, leaving just the underlying
technology of pcenv.
