Series processor) automatically force processor clustering. This allows for a maximum of 32 processors.Īlthough most systems with eight or fewer processors do not use cluster groups, some servers (such as those based on the Intel® Xeon® e5506 However, the bits are used to assign each processor to a cluster group. Multiprocessor systems that provide support for more than eight processors and those that implement processor clustering still use 8-bits to distinguish processors. Multiprocessor systems with a maximum of eight processors, that do not implement processor clustering, use an 8-bit CPU ID to identify each processor. This provides improved performance by allowing multiple threads to execute concurrently. The features of MPS-compliant multiprocessor systems. RTX supports both uniprocessor and multiprocessor-based systems running Has an “APIC x86-based PC” HAL installed. For example, in the figure below, the system The Windows Device Manager for the system and expand the “Computer” icon To determine the type of HAL installed on a particular system, open RTX does not provide support for the following standard Microsoft HAL: RTX provides support for the following standard Microsoft HALs: RTSS and Windows, basic exception management, and various enhancements HAL extension features include a software interrupt mechanism between It also supports non real-time clocks and timers for Windows. HAL extension supports high-resolution clocks and timers for RTSS, while Windows interrupts are masked during RTSS processing. Windows cannot mask (at the interrupt controller level) interrupts managedīy RTSS. This extension maintains interrupt isolation between RTSS and Windows. RTX includes a real-time enabled Hardware Abstraction Layer (HAL) extension. These systems are based on IA-32 (Intel Architecture, 32-bit) hardware. The RTX Runtime extends the Windows operating system, running on a 32-bit platform.
