The Intel iPSC/2 and iPSC/860 hypercubes have somewhat better libraries
than the old NCUBE. Included are functions for global syncs, multicast,
global reductions, interupt driven communication, and some other
useful stuff. I cannot speak for the NCUBE2, but the old NCUBE was
a real bear to work with because of the lack of any solid software support.

This is not to imply that Intel has done a very good job supplying system
software, just that NCUBE's is (or at least was) much worse.
