hi, For a course in computer architecture and vector processing which i am currently developing, I want to illustrate Hockney's classification of vector computers with some real examples. Bad luck. Hardware manuals give clock cycles, and even vector lengths but *no* vector setup times. I'm interested in the setup times for the Cyber 995E, but a reference to a nice little book surveying some more machines would be very nice Can anyone give a hint Hans Spoelder Physics Applied Computer Science Faculty of Physics and Astronomy Vrije Universiteit De Boelelaan 1081 1081 HV Amsterdam

Hans Spoelder requested vector setup times for Cyber 995. The following are the vector setup times for the 995E: N is the vector length (max of 512). Times are given as clock units which is 16 nsec for the 995. Thus, ADDXV takes 52 clocks to setup and produces a result per clock after that.
