摘要： A system and method for scheduling the number of channels in video-on-demand servers so as to deal with time varying load. The scheduling process is hierarchical. A higher level scheduler controls the rate of channel consumption based on anticipated load, and a lower level scheduler selects the waiting client requests to be served when a channel is allocated by the higher level scheduler.

摘要： A computer implemented method for minimizing the grant of pages locks and the number of outstanding locks while ensuring consistency of the copies of pages resident among a first, and a second data cache with the original pages in shared external storage. A first processor requesting a lock on a designated page is granted a lock over the group of pages including the designated page in the absence of a concurrent lock to the page or group held by another processor. Any changed page is copied through to external storage. Otherwise, a processor intending to alter a page causes a global lock manager to notify concurrent lock holders, invalidate copies of the page in their local caches, and obtain an exclusive lock to the requesting process for the duration of its operation on the page. After this the lock is demoted to share and the changed page also copied through to external storage.
摘要翻译：一种计算机实现的方法，用于最小化页面锁定的授予和未完成的锁定数量，同时确保驻留在第一和第二数据高速缓存中的页面的副本与共享外部存储器中的原始页面的一致性。在没有对另一处理器所保持的页面或组的并发锁定的情况下，在指定页面上请求锁定的第一处理器被授予包括指定页面的页面组的锁定。任何已更改的页面都将复制到外部存储。否则，打算更改页面的处理器会导致全局锁管理器通知并发锁持有者，使其本地缓存中的页面的副本无效，并在该页面上操作的持续时间内获取对请求进程的排他锁。之后，锁定被降级分享，更改的页面也被复制到外部存储。

摘要： A system and method for use in a distributed video-on-demand system of a type wherein at least one node provides blocks of video data to clients and wherein at least some of the blocks of video data are replicated on multiple nodes. Observed response characteristics for other nodes are recorded at least a given one of the nodes which serves a client requesting a replicated block. The given one of the nodes also records response characteristics reported to it by the other nodes. The node from which to fetch the replicated data block is selected based on which nodes include a copy of the replicated data block and based on at least one of the observed response characteristics and the reported response characteristics.

摘要： A computer implemented method for robustly copying pages to system managed storage in order to maintain data in a consistent state and in order to provide continuous access availability of the pages to executing applications. The method achieves data consistency by atomically shadow copying application referenced pages and amending directories in a failure independent medium on (1) an access path interrupt as well as on (2) a page update basis. Availability is enhanced by duplexing the pages and directories as part of the atomic shadow copying step.

摘要： A conditional broadcast or notification facility of a global lock manager is utilized to both serialize access to pages stored in local caches of counterpart processors in a distributed system and to ensure consistency among pages common to the caches. Exclusive use locks are obtained in advance of all write operations. When a page is to be updated, which page is cached in a processor other than that of the requester, then a delay is posed to the grant of the exclusive lock, all shared use lock holders to the same page notified, local copies are invalidated, exclusive lock granted, page is updated and written through cache, after which the lock is demoted to shared use.

摘要： A system and method are provided for determining load capacity of a system. Physical components of the system and their interconnection are identified. The physical components are converted into logical components such that at least one logical component is created by grouping a plurality of the physical components and such that a load on the logical component will result in an approximately fixed proportional load on the plurality of physical components. Links between the logical components and a proportion of the load placed on each link between a source and destination pair are determined. A model of the logical components and interconnection of the logical components in is then stored in an electronically accessible data structure formed in a memory. A system and method for determining a path for routing data between a source and a destination pair in a system are also provided. An interconnection model of logical system components and logical links is provided wherein the model reflects the saturation capacity of each of the logical system components and each of the logical links. The bandwidth required for providing the data is determined. Then, by reference to the model, a path between the source and destination pair is selected that would not saturate any of the logical system components and logical links when providing the data. System capacity is then reserved by altering the model to reflect the load on the system components that would be required by providing the data from the source to the destination by way of the selected path.

摘要： A method for managing concurrency using a serializing token as a supplement to locks for accessing the same page by different processes and ensuring coherence between data caches and a shared access backing store supporting the processes defined onto multiple processors. A shared lock and a new token are issued by a local lock manager (LLM) and local cache manager (LCM) in response to a page read request from a process. An exclusive lock, an invalidation of all cache resident copies of the page, a cache write through to backing store of the changed page, a copyback of a new token, and lock release are responsive to a page write/update request from a process where the token issued to the process during a prior request matches the token stored with a cache resident copy of the page. Otherwise, a write request fails and the process must first issue a read request to the page of interest.

摘要： A computer-implemented method for the name-oriented accessing of files having at least zero records, any access path to files and records through an external store coupling the computer being defined by a pair of related directories. A first directory of record entries is sorted on a two-part token. The token consists of a unique sequence number assigned to the record and the sequence number of any parent record entry. Each record entry includes the token, file or record name, and external store address or pointer A traverse through the tokens constitutes a leaf-searchable B-tree.Rapid access to target records is by way of a name-sorted, inverted directory of names and tokens as a subset and which is reconstitutable from the first directory in the event of unavailability.

摘要： A method to manage the access of data or pages mapped into a very large virtual external address space through a cache without disturbing the logical view of the data and without having to assign physical or real backing store to said logical view. A data cache is used in which pages are indexed according to a logical address intermediate to their virtual address and their physical location in external storage. Pages common to two or more files are updated in place in the cache, while pages bound to only one file are shadow copied.

摘要： Techniques are disclosed for combining multiple benchmarks for use in assessing characteristics of a computing system. For example, a method for configuring and running multiple benchmarks includes the following steps. A multiple benchmark specification is obtained. The multiple benchmark specification includes multiple individual benchmark specifications and a multiple benchmark workflow describing an ordering according to which the multiple individual benchmarks are to be configured and run. The multiple benchmarks are configured and run according to the ordering identified in the multiple benchmark workflow. Results of the multiple benchmark runs are recorded. One or more specifications or results associated with at least one of the multiple benchmarks are utilized as part of a benchmark specification for at least another of the multiple benchmarks so as to provide consistency between at least the one and the other of the multiple benchmarks.
