LogP is a general-purpose adaptive parallel model so not tied to a specific architecture. However, I too am curious if anyone knows the Cell lineage and if there is a connection. A cursory search on Google Scholar [1] shows the LogP paper is cited more than 2000 times, but I did not see a direct lineage reference between the IBM Cell architecture [2] and the Berkeley LogP model [3]. Does anyone know the history and if there is a connection?
