What specifically makes Intel's Core and Core 2 processors appealing compared to a discrete dual-processor system? This article takes an in-depth look at the advantages that accrue from Intel's new architecture.
Virtualization on multi-core and multi-processor systems
The more CPUs you have available in a computer that runs virtualized machines, the more processing power you can share among the virtual computers. But the presence of multi-core CPUs complicates the picture a little bit. Can a computer with four physical processors support the same virtualized load as a two-CPU system with two cores per CPU? This tip offers some guidelines about using multi-core systems with virtualization.
How 64-bit version of Windows differs architecturally from 32-bit version
Looking at 64-bit versions of Windows from a user's standpoint, 64-bit applications simply run side by side with 32-bit applications. But for administrators (and members of the help desk), it's a different story. This tip looks into the registries x64 versions of Windows have for 64-bit code and one for 32-bit code.
Does XP support multiple processor cores?
Many differences exist between Windows XP Home and Windows XP Professional – many of them well-documented. One of the most significant is XP's support for multiple physical processors. As two- and four-processor workstations (not just servers) become more common, whether or not they're supported by the operating system running on them in the first place is critical. This tip looks at what XP Professional and XP Home support in terms of multiprocessor cores.
