if you want to look at other various ... Jan1979, I was con'ed into
doing benchmarks on engineering 4341 for national lab that was looking
at getting seventy for a compute farm (sort of leading edge of coming
cluster supercomputing tsunami).

in the wake of Future System failure, the was mad rush to get
products back into 370 pipeline (internal politics had been
shutting down 370 efforts) and 3033 (168-3 logic mapped to
20% faster chips) and 3081 were kicked off in parallel. some
history
http://www.jfsowa.com/computer/memo125.htm

they took 158 engine w/o the 370 microcode and just the integrated
channel microcode for the 303x (external) channel director. then the
3031 is a 158 engine with just the 370 microcode (no integrated channel
microcode) and a 2nd 158 engine with the integrated channel microcode
(and no integrated channel microcode). A 3032 is 168-3 configured to
use channel director for external channels ... and 3033 is 168-3 logic
remapped to 20% faster chips.

158  45.54 secs
3031 37.03 secs
4341 36.21 secs
168-3 9.1  secs
91    6.77 secs

and real historic cdc6600 35.77 secs

158-3 (158 engine running both 370 and integrated channel microcode) was
45.54 secs compared to 3031 (that was two 158 engines, one for 370 mcode
only and one for channels mcode only) was 37.03 secs.
