Through my investigation for writing about the parallel computing,
I found there are many "incoherences" and "inconsistencies" all over various terminologies regarding parallel computing.
I guess surrounding environment is so fastly changing, the center of excellence of this research field has been moved very frequently.

Most of significant works had been done in the era of sequential computing.
But for very near future, we will be going into the era of parallel computing. The terms that had been spawned in the hypothetic world would get real body and require coherent and consistent definition of themselves.
