Greg Pfister has stated that clusters were not invented by any specific vendor but by customers who could not fit all their work on one computer, or needed a backup.<ref>{{cite book | last = Pfister | first = Gregory | title = In Search of Clusters | edition = 2nd | publisher = Prentice Hall PTR | ___location = Upper Saddle River, NJ | year = 1998 | page = [https://archive.org/details/insearchofcluste00pfis/page/36 36] | isbn = 978-0-13-899709-0 | url = https://archive.org/details/insearchofcluste00pfis/page/36 }}</ref> Pfister estimates the date as some time in the 1960s. The formal engineering basis of cluster computing as a means of doing parallel work of any sort was arguably invented by [[Gene Amdahl]] of [[IBM]], who in 1967 published what has come to be regarded as the seminal paper on parallel processing: [[Amdahl's Law]].
