Clive England and David Laufer have presented their slides for their talk about the Cray-2 computer earlier this year. Full of facts on this amazing machine.
Four best features of the Cray-2
• Density of electronics, it’s a very small machine compared to contemporaries.
• Speed of processor using a 4 nanosecond clock – way ahead of its time
• Size of main memory – up to 30 times size of Cray-1 & XMP – could run problems that would bog down on other systems. Very good at CFD codes.
• First Cray with direct interactive access for users alongside batch work. Due to using Unix as base for Unicos operating system
