Hi Chathuri,
I do not know anything about Gaussian. So its kind of hard for me to
understand what exactly is the meaning of the structures you introduced and
why you exactly need those structures.
A more important question is how to come up with a more abstract and
generic thrift IDLS so that you dont need to change it every time we add a
new application. Going through many example applications is certainly a
good way to understand broad requirements and helps to abstract out many
features.
Thanks
