摘要： Systems and methods for scheduling program units that are part of a process executed within an operating system are disclosed. Additionally, at least one thread is started within the operating system, the thread is associated with the process. Further, a plurality of streams within the thread are selected for execution on a multiple processor unit. Upon the occurrence of a context shifting event, one of the streams enters a kernel mode. If the first stream to enter kernel mode must block, then the execution of the other streams of the plurality of streams is also blocked.

摘要： In one embodiment, a method and apparatus for ring optimization for data sieving writes is disclosed. The method includes dividing a file range to be written to via a data sieving write operation into N groups, where N is greater than or equal to a number of processes writing to the memory, determining an offset assigned to each process, the offset being a distance from a beginning of the file range at which each process starts its writing, simultaneously writing by each process to the group of the file range determined by the associated offset of each process, and moving, by each process, to the next available subsequent group when a process completes the writing. Other embodiments are also disclosed.

摘要： A system includes a memory, a plurality of pages held in the memory, an instruction translation look aside buffer (ITLB), a first data translation look aside buffer (DTLB), and a translation look aside (TLB) miss handler. The system also includes an executable/non-executable (x) indicator associated with each page in memory. The TLB miss handler sets the x-indicator for a particular page to indicate “non-executable” when that page is accessed in a mode that allows writing to that page. The ITLB or the ITLB miss handler refuses to allow instructions from a page with an associated x-indicator of “non-executable” to be loaded into the instruction buffer.
