A method and system for secure automated deployment of an emulated computer system. The method includes providing a download package for installation on a target machine. The download package includes a generic emulated computer system having no unique identity, no model identity, no features, and minimal processing components. The download package also includes a customer order file based on an order from a customer of the target machine. The customer order file includes a machine identity, at least one machine capability, and control data. The download package also includes at least one enabling key configured to enable the emulated computer system on the target machine. The enabling key is customized based on the order from the customer of the target machine, and includes identity information that restricts the use of the emulated computer system on any computer system other than the target machine. The method also includes delivering the download package to the target machine for installation of the emulated computer system on the target machine. The download package prevents the unauthorized cloning of the emulated computer system onto any hardware platforms other than the target machine, and prevents the unauthorized use of any hardware other than the hardware of the target machine.

Method and system for secure automated deployment of emulated computer system

A method and system for maintaining the execution speed of a multiprocessor computer system includes automatically detecting a change in instruction execution rate in a disabled processor by a threshold amount and determining an amount of change in instruction execution rate to adjust an actual system-level instruction execution rate to approximate a target system-level instruction execution rate. The target system-level execution rate being pre-determined. Thereafter, the method adjusts one or more instruction processor execution rates such that the actual system-level instruction execution rate approximates the target system-level instruction execution rate to overcome the loss of the disabled processor. One embodiment of the invention involves the use of a processor key for licensing of processor resources within the computer system and offers the option of enabling a dynamic processor recovery method as well as an automatic execution rate regulation method.

A computer system comprises a plurality of processing modules that can be configured into different partitions within the computer system, and a main memory. Each partition operates under the control of a separate operating system. At least one shared memory window is defined within the main memory to which multiple partitions have shared access, and each partition may also be assigned an exclusive memory window. Program code executing on different partitions enables those partitions to communicate with each other through the shared memory window. Means are also provided for mapping the physical address space of the processors in each partition to the respective exclusive memory windows assigned to each partition, so that the exclusive memory windows assigned to each partition appear to the respective operating systems executing on those partitions as if they all start at the same base address.
