Abstract: In a computing system having swappable and non-swappable address spaces, wherein the computing system includes an operating system that includes a Real Storage Manager (RSM), a Systems Resource Manager (SRM) and a Region Control Task (RCT), a method for recovering swappable fixed non-preferred memory is provided which includes receiving a request from the operating system to configure an area of real memory to create an intercepted swappable address space, wherein the intercepted swappable address space includes a flagged fixed frame element identified for configuration, examining the intercepted swappable address space so as to determine if the intercepted swappable address space will remain swappable, requesting the SRM to coordinate the swapping process, quiescing the intercepted address space, generating a first return code responsive to the intercepted swappable address space remaining swappable, communicating the first return code to the RCT so as to cause the RCT to respond to the first return code, in

Abstract: A slave pulsed laser stabilizes the frequency by using the master laser frequency to stabilize a cavity in the slave pulsed laser. The slave pulsed laser includes an optical modulator, a cavity, a cavity modifier, and an output generator. The cavity includes an end reflector, a laser generator, an optical injector, and an output coupler. The optical modulator receives a continuous wave laser signal that includes a carrier frequency. The optical modulator then modulates the continuous wave laser signal to generate two sidebands around the carrier frequency. The laser generator generates a first laser signal in the cavity. The optical injector then injects the continuous wave laser signal with the first laser signal. The output generator generates an output signal based on the continuous wave laser signal. The cavity modifier then modifies a length of the cavity based on the output signal wherein the cavity is in resonance with the frequency of the continuous wave laser signal.

Abstract: An addressing method and computer system for sharing a large memory address space using address space within an operating system's virtual address space. The system provides sharing the SSB over many processes without the disadvantages associated with process based global sections. For instance, the novel system does not require that each process maintain its own dedicated page table entries (PTEs) in order to access the SSB thereby requiring less operating system virtual memory to maintain the PTE data structures. The system uses a process to switch to kernel mode, then identifies those sections of the operating system virtual memory space that are not being used; in some cases the unused address space can be 1.5-1.8 gigabytes in size. The unused address space is linked together to form the SSB. The system alters the privileges of the PTEs corresponding to the SSB so that user mode processes can access this usually protected operating system virtual memory space.
