Nope. It's 100% x nCPUs. And if the CPUs are HyperThreading CPUs, then there's another factor of 2. But the x2 for HT is an overestimate, since HT is not a full duplication of the execution machinery and cannot always sustain two fully independent and arbitrary instruction streams--they'll sometimes interfere with each other when both need the same bit of execution, on-chip storage or data path circuitry. > -- > Salam, > > Adi Nugroho Randall Schulz -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
