Elxsi and Convex too, I think. Last time I checked (and I checked Pyrmaid recently) Arete, Pyramid, and Elxsi were not 12 MIPs. The bus on the new Gould is much faster than every CPU you listed. There are two big advantages of the Gould. One, it achieves it's speed using a small number of processors which makes it more attractive to some of the number crunchers than it would seem to someone who is just going to dump 100 users on the machine (which is where the ENCORE really excels). The other big point is the ability for some really fast disk technology to be used. Fast disks make UNIX sing. For example, the C compiler on most machines is limited by the disk speed. Find the fastest disk you can, make it /tmp and watch the performance change. Still, both this offering from Gould, and the recent offerings from DEC are very UNDERWELMING. Gould's previous top of the line machine, the PN9000, was pushing 10 mips as it was. This new processor isn't a very big jump for two or three years elapsed time. It would seem to me that we ought to be in the 20 mips range per processor now. DEC is essentially pedelling the same old computer, clustered up in a form which pretends to be competing with the newer IBM processors. The effect of this approach has been seen in DEC processors over the years. You end up paying close to N times as much (where N is the number of processors) and receive less than N times the performance increase. If only the big IBM's weren't such a bitch to talk to... -Ron
