Hi
Glue-less means that no other silicon is necessary to connect the processors together. For example, The Nehalem EX with four full QPI can support glue-less 8-way system architecture. Each processor connects directly to all seven other processors with a half-wide QPI link, and uses the remaining half wide QPI to connect to the IOH.

I dont know any embedded dictionary port so wide to cover everything. Sorry.
