Answer: Anybody with a large problem to solve or a problem to solve quickly which can be mapped onto such an architecture. For example: Dow Jones wants to supply a service to their tens of thousands of customers, to let them search, for example, the New York Times articles for the past 10 years, for all occurences of "not a crook" and "national security" within the same paragraph. The Connection Machine(with a piddly 64k processors) does a fairly bangup job of this. I suspect the human genome problem is another candidate for massively parallel processing. The key to making MPP work lies in NOT having to program for it explicitly. That is where languages such as J should be helpful -- reflect the way we think, rather than the way computers are built. When I was Director of Research at I.P. Sharp (bought out by Reuters, arch-enemy \\\\\competitor\\\\\\\\\\honorable opponent of Dow Jones), I proposed we get an CM2 to look at such applications. This was refused by the forward-thinking management of Reuters, who were happily exploring ideas such as mediocrely parallel systems, and farms of sun workstations. I think both ideas, and the people who were pushing them, are no longer at Reuters either. Food for thought... Bob Bernecky Snake Island Research Inc. ps: I'm not there any more either.
