You are wrong. Last ccNuma was pushed out of top100 more than a decade ago. All top machines today are MPP or clusters.=20 Not that a diffference between the two is well-defined. After consulting Wikipeadia, it's probably far more than a decade. The last one that I thought to be ccNuma, was in fact a cluster of 10 ccNuma computers. https://en.wikipedia.org/wiki/Columbia_(supercomputer)
