Re: [Libmesh-users] Syncronize a vector among processes

[Renato P. <re...@gm...>]

Nice. It is important to identify the source of that value (elem. number,
for example).
Is it safe to use the template parameter <T> as a custom class overriding
the sorting operators?

Something like:

class MyClass {
    double number_to_classify;
    unsigned int elem_id;
    operator< ( ... ) { ... number_to_classify ...}
}
