Abstract: This disclosure describes systems, methods, and devices related to a global address space (VEGAS) approach. The device may execute at least two processes within a device in a computing environment, each process running on a respective compute block of at least two compute blocks. The device may manage allocations of virtual memory spaces for the least two compute blocks using an independent logical system separate from the at least two compute blocks. The device may isolate the virtual memory spaces of the at least two processes by allowing each compute block to access only its own allocated virtual memory space.

Abstract: In an embodiment, a processor comprises: an execution circuit to execute instructions; at least one cache memory coupled to the execution circuit; and a table storage element coupled to the at least one cache memory, the table storage element to store a plurality of entries each to store object metadata of an object used in a code sequence. The processor is to use the object metadata to provide user space multi-object transactional atomic operation of the code sequence. Other embodiments are described and claimed.

Abstract: Systems and methods for accurately calculating radiation doses in biological tissues exposed to a radiation source are provided. In the systems and methods first, a radiation dose is computed to geometry of water equivalent medium of the biological tissues, expressed in computed tomography (CT) volumetric images. A Medium-Dependent-Correction factor that is a function of an effective bone depth matrix and the incident x-ray beam is obtained and tabulated. Using patient material and density data derived from CT images, the effective bone thickness can be calculated from a specific x-ray source. Finally, a Medium-Dependent-Correction factor that is a function of an effective bone depth matrix is used to accurately determine the radiation dose distributions to biological tissues.
