As I understand things, the POWER5, like the POWER4, is a dual-core processor. Meaning, each chip module actually has 2 CPU's on it. If that is the case, then why are most of the 520's labelled as single processor systems? Are they really single module, but 2 CPU systems or does IBM do it's "governor" BS to actually only use one of the CPU's? Also, POWER5 implements Simultaneous Multi-Threading (SMT) which means each CPU should look like 2 CPU's to the operating system, just as my dual-Xeon xSeries servers look like 4 processors to Windows because of Intel's HyperThreading technology. So, given all of that, shouldn't a single processor POWER5 really look like a 4-way system to OS/400, given that the single chip module should have 2 processors, and each processor should look like 2 processors because of the SMT?
