Once you recognize that I/O is eating up your precious CPU, and you

CDC 6600 Peripheral Processors, programmed in code or microcode.

Jan1979, I had lots of use of an early engineering 4341 and was con'ed
into doing a (cdc6600) benchmark for national lab that was looking for
70 4341s for computer farm (sort of leading edge of the coming cluster
supercomputing tsunami). Benchmark was fortran compute doing no I/O and
executed with nothing else running.

Do you have data on how the CDC 6600 did ?

now integrated channel microcode ... 158 even with no I/O running was
still 45.64secs compared to the same hardware in 3031 but w/o channel
microcode: 37.03secs.
