Here are a bunch of questions about the MassComp MC-500. Thanks in advance for any info or help you might be able to give me. I have seen a few of the reported benchmarks on the network about the MassComp MC-500. Does anyone know what they did to make their machine so fast? Is this just a machine that is fast because of a lot of hardware and thus mortals can not afford to own it? Did they do a "real Unix" or is this a look-alike. Is there anything special about their software? Is it Sun class or a Vax class machine? Who *are* these guys anyway? Are they shipping yet, i.e. can I *really* get a machine? Does anyone have one of these machines? I have heard all sorts of wonderful things from MassComp people, and from what I saw at Usenix, the box was pretty impressive. Is there anyone who does not work for them that has similar wonderful (or terrible) things to say? -Dan Klein, Mellon Institute, Pittsburgh

What seems to make the MassComp 500 fast is (a) a 4k cache on the cpu board, (b) a high speed buss along-side the massbuss for fast memory access. My guess would be that the cache makes all the difference. The cpu chip itself is a 10mhz 68000, with a helper 68000 for paging. The Unix seems to be a port, not a look-alike. The benchmarks from Masscomp make it vax-750-like, depending on the disk, etc. I wouldn't actually call this Vax-class since it is well below a 780, but it considerably better than a Sun. I haven't done my own benchmarks, however. They ARE shipping--around 100 machines are out there, if I remember right, including two right in my neighborhood. Don't have one myself yet, but I'm talking to them. I am very impressed by the packaging and hardware design of these folks. Their software seems solid as well, but I haven't looked at the code. The software people I have talked to knew their stuff. I consider the prices to be Sun competitive, and a lot better than a vax 750 if the benchmarks old up. They have a local sales organization in many areas, call them up and ask for information. Tell them Mark Weiser at the U. of Maryland sent you. -- spoken: mark weiser UUCP: {seismo,allegra,brl-bmd}!umcp-cs!mark CSNet: mark@umcp-cs ARPA: mark.umcp-cs@UDel-Relay
