CDC 6500 and 6700
Control Data Corporation offered two configurations of its CDC 6000 series that featured two processors. The CDC 6500 was a CDC 6400 with two processors. The CDC 6700 was a CDC 6600 with the CDC 6400 processor added to it.
These systems were organized quite differently from the other multiprocessors in this article. The operating system ran on the peripheral processors, while the user's application ran on the CPUs. Thus, the terms ASMP and SMP do not properly apply to these multiprocessors.
