It's also possible that the C compiler (this is not gcc by the way) generates far less than optimal code. The heavy duty programs were generally written in Fortran if I'm not mistaken. In general I would suspect that GNU Go doesn't take advantage of a single one of the good features of a Cray Y-MP. Still it's striking how extremely bad it performs. /Gunnar
