20110107342 | PROCESS SCHEDULER EMPLOYING ORDERING FUNCTION TO SCHEDULE THREADS RUNNING IN MULTIPLE ADAPTIVE PARTITIONS - A system is set forth that includes a processor, one or more memory storage units, and software code stored in the one or more memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality, of adaptive partitions has one or more corresponding scheduling attributes that are assigned to it. The software code further includes a scheduling system that is executable by the processor for selectively allocating the processor to run the process threads based on a comparison between ordering function values for each adaptive partition. The ordering function value for each adaptive partition is calculated using one or more of the scheduling attributes of the corresponding adaptive partition. The scheduling attributes that may be used to calculate the ordering function value include, for example, 1) the process budget, such as a guaranteed time budget, of the adaptive partition, 2) the critical budget, if any, of the adaptive partition, 3) the rate at which the process threads of an adaptive partition consume processor time, or the like. For each adaptive partition that is associated with a critical thread, a critical ordering function value also may be calculated. The scheduling system may compare the ordering function value with the critical ordering function value of the adaptive partition to determine the proper manner of billing the adaptive partition for the processor allocation used to run its associated critical threads. Methods of implementing various aspects of such a system are also set forth. | 05-05-2011 |

20110072060 | FILE SYSTEM HAVING TRANSACTION RECORD COALESCING - An electronic data system comprises memory storage having stored data, file system software, and a transaction file. The transaction file is maintained by the file system software, and includes a plurality of transaction records corresponding to transactions that have been or are to be executed on one or more files and/or the or more directories of the file system. The file system software operates to organize and maintain the stored data in the files and directories and also to coalesce multiple transaction records meeting one or more criteria into fewer coalesced transaction records. The physical memory space required by the transaction file is reduced by the transaction record coalescing. The coalesced transaction records may be constructed so that they represent a logical result of applying each transaction record of a transaction record set in chronological order. Once the coalesced transaction records have been committed in the file system, the physical memory used by the original transaction records in the set may be reclaimed for further use (e.g., to store further transaction records) or may be otherwise removed from further use (e.g., when the physical memory is located in a block of memory in a flash-like memory device that has reached its maximum number of write and/or erase cycles). | 03-24-2011 |
20110072061 | OPTIMIZED STARTUP VERIFICATION OF FILE SYSTEM INTEGRITY - A computer system that may be used in implementing a transaction based file system is disclosed. The computer system includes a processor, random access memory that may be accessible by the processor, and a persistent data storage device that is likewise accessible by the processor. The computer system also may include file system software. The file system software may be executed by the processor and operates to manage the file data and the file system structure of the files stored on the persistent data storage device. Additionally, the file system software may maintain a transaction file that includes a plurality of transaction records. Each of the transaction records has a header section and a data section. The header section of each transaction record may include one or more fields that are designated to store information corresponding to a file transaction that is represented by the transaction record. If the operation of the file system software is interrupted, the file system software may resume its execution using a startup process in which a reconstructed file system may be generated in the random access memory. During system restart, the startup process may skip verification of the data section of a transaction record when the transaction record meets one or more predetermined criterion. For example, the startup process may make a distinction between transaction records merely affecting file data versus transaction records that affect the metadata of the file system. As transactions are found during the startup process, the file system software may identify whether a transaction impacts file data or metadata. Since only the metadata is required to ensure that the file system is in a consistent state after startup, the transaction records relating to metadata may be selected as the only subset of transaction records that are subject to complete verification. Verification of other transaction records may, for example, be limited to a check of the information contained in the header section of each remaining transaction record. | 03-24-2011 |

20130247066 | Process Scheduler Employing Adaptive Partitioning of Process Threads - A system includes a processor and memory storage units storing software code. The software code comprises code for a scheduling system and for generating a plurality of adaptive partitions that are each associated with one or more process threads and that each have a corresponding processor budget. The code also is executable to, when the system is under a normal load, allocate the processor to one of the threads that is in a ready state and has the highest priority among the process threads that are in a ready state. The code is also executable to, when the system is in overload, allocate the processor to one of the process threads that is in a ready state and has the highest priority among the process threads that are in a ready state and for which the adaptive partition that the process thread is associated with has available guaranteed processor budget. | 09-19-2013 |
20140245311 | ADAPTIVE PARTITIONING FOR OPERATING SYSTEM - An adaptive partition scheduler is a priority-based scheduler that also provides execution time guarantees (fair-share). Execution time guarantees apply to threads or groups of threads when the system is overloaded. When the system is not overloaded, threads are scheduled based strictly on priority, maintaining strict real-time behavior. When the system is overloaded, threads are scheduled based priority of threads that are in a ready state and based on the available guaranteed processor time budget of the adaptive partition associated with each thread. | 08-28-2014 |
