[Trilinos-Users] TPetra Preference for "long long" Global Ordinal Type

[Corey A. Henderson]

I was looking into why I had trouble linking with TPetra when I chose
unsigned Global Ordinal types and explicit template instantiation, and
found this:

https://github.com/trilinos/Trilinos/blob/master/packages/tpetra/doc/FAQ.txt

It indicates that unsigned ordinals are not preferred. Can someone
explain why that is? Is there some use case I don't see that leads to
negative global ordinals?

I'm relatively new to this so if this is a dumb question, that's my excuse.
