They had a latge > quicksort running at 1.7 times the speed of doing it in local memory only. > > http://www.cluster2005.org/122.html "1.7x slower" according to the abstract. at first glance at least, it's not really an impressive result - the sort would have been much faster if they had simply done a parallel qsort, rather than using a bunch of slaves as dumb/passive block-memory servers. or is someone actually proposing IB boxes with no real CPU but lots of ram?
