International Classification:

G06Q 30/00
G06F 3/01
G06F 3/048

Abstract:

Electronic advertisements and other types of electronic information are distributed based on user profiles and in particular, collections of widgets. User profiles may be generated based on a combination of user searches for specific items or points of interest. Alternatively user interests may be determined by the customized tabs setup by said user for his own personal web portal. User entered information and information inferred or derived from user behavior and interaction patterns may be used to determine the type of directed advertisement to be targeted to a specific user. The use and collection of various widgets may also be recorded by a user profile to determine a user's preferences and interests. An advertisement may be distributed by segmenting a user population according to user profile information and one or more attributes of the advertisement. Users may further interact with the widgets in a variety of ways including specifying product request details such as make, model, price and color, requesting additional information about the advertised product or service and/or requesting communications with an advertiser without compromising their privacy. Thus, unnecessary surfing of the internet may be eliminated for updated information and internet commerce.

International Classification:

G06F 12/02

US Classification:

711170, 711E12002

Abstract:

Large page memory pools are managed. Thresholds are used to determine if the number of pages in a large page memory pool is to be adjusted. If the number of pages is to be increased, a particular technique is provided for adding additional pages to the pool. Further, if there are too many pages in the pool, one or more pages may be removed.

International Classification:

G06F 12/02

US Classification:

711171, 711E12002

Abstract:

Allocation of pages of memory is managed in computing environments that include multiple sized memory pools. Responsive to a request for a page of memory, one or more memory pools are searched for an available frame of memory to service the request. The search uses a predefined order of search, which includes multiple types of memory pools in a specific order based on the requested size of the page of memory.

International Classification:

G06F 12/02

US Classification:

711170, 711E12002

Abstract:

Dedicated large page memory pools are provided to, at least in part, facilitate access to large pages. The large page memory is managed by: establishing multiple large page memory pools, each large page memory pool of the multiple large page memory pools including a number of large pages; and dedicating each large page memory pool of the multiple large page memory pools to a respective processor of multiple processors of the computing environment, wherein processors of the multiple processors can concurrently access pages from the respective large page memory pools of the multiple large page memory pools.

US Classification:

711163, 702186, 711E12098

Abstract:

A method for obtaining a measurement of storage usage includes sending a request, by a processor, for the measurement of storage usage during execution of an application by the processor; counting blocks of storage to generate the measurement of storage usage by the application; and providing the measurement of storage usage to the application.

International Classification:

G06F 12/10

US Classification:

711207, 711E12061

Abstract:

A computer system includes a translation look-aside (TLB) buffer and a processing unit. The TLB is configured to store an entry that comprises virtual address information, real address information associated with the virtual address information, and additional information corresponding to at least one of the virtual address information and the real address information. The processing unit is configured to control the TLB to modify the additional information while maintaining the entry in a valid state accessible by the processing unit for a translation look-aside operation corresponding to the virtual address information and the real address information.

International Classification:

G06F 11/20

US Classification:

714 63, 714E11089

Abstract:

A fault occurs in a virtual environment that includes a base space, a first subspace, and a second subspace, each with a virtual address associated with content in auxiliary storage memory. The fault is resolved by copying the content from auxiliary storage to central storage memory and updating one or more base space dynamic address translation (DAT) tables, and not updating DAT tables of the first and second subspace. A subsequent fault at the first subspace virtual address is resolved by copying the base space DAT table information to the first subspace DAT tables and not updating the second subspace DAT tables. A fault occurring with association to the virtual address of the first subspace is resolved for the base space and the base space DAT table information is copied to the first subspace DAT tables, and the second subspace DAT tables are not updated.

International Classification:

G06F 12/00

US Classification:

711170, 711E12002

Abstract:

A computer system includes memory and a processor configured to manage memory allocation. The processor is configured to execute a memory allocation request to allocate a portion of the memory to an application by determining whether a size of the memory allocation request is less than a first pre-defined size. The processor searches virtual memory for a free allocated memory area corresponding at least to the size of the memory allocation request based on determining that the size of the memory allocation request is less than the first pre-defined size.
