Hello Super-Users and Administrators and Operators,

we have here discussions about the replacement of our VP-100, so I would
like to here some opinions about the relation of

Brutto speed ( Mflops )  to

main memory size and

IO-rate

one should have.

The machine should have a brutto power of appr. 1 Gflop. We are a university
with mostly technical sciences, so more than half ( perhaps 60-80 % ) will
go to such applications. We have appr. 1500 scientists, appr. 10000 students,
( who will of coarse use this machine for the final thesises only, if at all ).

The machine will run under some flavour of Unix, interactive use will happen
at least for development.

How will access via X-terminals affect the configuration of the machine ?

How can a high speed DRAM 'disk' be traded against main memory ?
( many supers have such a storage behind main memory for fast swapping etc.)

How important or unimportant would you consider the existance of virtual
memory ? How would this influence the IO-rate needed ? the size of main
memory ?

Thanks a lot for all responses to the group or by mail, i'll summarize
if I get useful responses.
