Hi, . Im not an MVS SYSPROG nor a hardware person, I am a CICS SYS Prog. . I always thought that CPUS (engines) were physical hardware. Is this not true anymore ? . The other day in a meeting I heard the term Logical/Virtual CPU. Never Heard that term. . . What exactly is a Logical/Virtual CPU ?
Does a Logical/Virtual CPU need to be backed by a Physical CPU ? . My understanding is a Task (TCB) in an address spaces always requires a CPU to be assigned/associated with. So with Logical/Virtual CPUS, can I have more TCBS, actively dispatched at the same time in the same Address Space, than the Physical CPUs ? . . curious minds want to know Paul
