The problem is that, as of now, a large number of questions are tagged "cluster" (close to 400), most of them actually refer to computer clusters. To make things worse, these two topics are not always mutually exclusive; think of scaling cluster-analysis algorithms in a cluster of computers environment.
I propose a group effort to fix/cleanup this mess... We have two choices:
- black-list "cluster" tag and assign all those questions as one of the two choices, or
- only re-tag the subsets of questions referring to "cluster-analysis", and let all others be merged with "cluster-computing" using synonym tags.
I have gone through the entire list of "cluster" questions, and re-tagged as "cluster-analysis" where appropriate. Now almost all of what remains refers to "cluster-computing".
