Hi, This may be the wrong place to ask this question, but I could not find any other appropriate newsgroup. My question is - What do the numbers at the end of 'Cray X-MP' mean in the name of the machine? e.g. What does the 12 mean in 'Cray X-MP/12' or the 48 in 'Cray X-MP/48' ? I do not usually read this newsgroup, so I will appriciate it if you send e-mail to sushil@pixel.cps.msu.edu, in case you know the answer. Thanks, Sushil

The following ambiguity may someday occur: Y/MP 164 == 16 processor Y/MP with 4 MW of memory Y/MP 164 == 1 processor Y/MP with 64 MW of memory (The first configuration is unreasonable, but technically feasible (sort of))

Thanks. > I assume the numbers have something to do with the numbers of banks and/or > cpus. > In some cases, you may see conventions such as 'X-MP4/28' or 'Y-MP8/4128'. In these examples, the '4' in 'X-MP4/28' means the total number of cpu's that the system can hold, and the '28' means that the system has '2' cpu's installed along with '8' mega-words of on-board memory. The same is true for the Y-MP. --Al -- Al Viall INTERNET: alv@pancake.cray.com Corporate Computing and Networks FIDO: 232/2,3 Cray Research, Inc. UUCP: ...!umn-cs!timbuk!ferris!alv
