Abstract: Generating approximate usage measurements for shared cache memory systems is disclosed. In one aspect, a cache memory system is provided. The cache memory system comprises a shared cache memory system. A subset of the shared cache memory system comprises a Quality of Service identifier (QoSID) tracking tag configured to store a QoSID tracking indicator for a QoS class. The shared cache memory system further comprises a cache controller configured to receive a memory access request comprising a QoSID, and is configured to access a cache line corresponding to the memory access request. The cache controller is also configured to determine whether the QoSID of the memory access request corresponds to a cache line assigned to the QoSID. If so, the cache controller is additionally configured to update the QoSID tracking tag.

Abstract: In an approach for taking corrupt portions of cache offline during runtime, a notification of a section of a cache to be taken offline is received, wherein the section includes one or more sets in one or more indexes of the cache. An indication is associated with each set of the one or more sets in a first index of the one or more indexes, wherein the indication marks the respective set as unusable for future operations. Data is purged from the one or more sets in the first index of the cache. Each set of the one or more sets in the first index is marked as invalid.

Abstract: A system, computer-readable medium, and method of visualizing memory utilization by a computing device are provided. In the method, a user interface window is presented in a display. The user interface window includes a first indicator representing a first datum stored in a first memory and a second indicator representing a second datum stored in a second memory. A first access speed for accessing the first memory is faster than a second access speed for accessing the second memory. A determination is made that the second datum is not stored in the first memory, but is ready for access by the processor from the first memory. In response, an update to the user interface window is presented in the display including a line connecting a first location of the first indicator with a second location of the second indicator.

Abstract: Provided are a computer program product, system, and method for determining cache performance using a ghost cache list. Tracks in the cache are indicated in a cache list. A track demoted from the cache is indicated in a ghost cache list in response to demoting the track in the cache. The demoted track is not indicated in the cache list. During caching operations, information is gathered on a number of cache hits comprising accesses to tracks indicated in the cache list and a number of ghost cache hits comprising accesses to tracks indicated in the ghost cache list. The gathered information on the cache hits and the ghost cache hits is used to generate information on cache performance improvements that would occur if the cache was increased in size to cache tracks in the ghost cache list.

Abstract: Described are various embodiments of systems, devices and methods for generating locality-indicative data representations of data streams, and compressions thereof. In one such embodiment, a method is provided for determining an indication of locality of data elements in a data stream communicated over a communication medium. This method comprises determining, for at least two sample times, count values of distinct values for each of at least two distinct value counters, wherein each of the distinct value counters has a unique starting time; and comparing corresponding count values for at least two of the distinct value counters to determine an indication of locality of data elements in the data stream at one of the sample times.

Abstract: Software solutions in a business software framework can expose their data via web services, which can readily provide access to all non-customized fields of objects included as part of the default installation of the software solution. However, customer-added extensions, such as for example custom fields and the like, added to customize the software solution for a specific business or business use can be difficult to add to web services by a typical business user who lacks technical abilities. Described herein are approaches to enabling addition of custom fields to web services via an intuitive interface that does not require technical understanding of the software solution, the business software framework, web services, etc.

Abstract: Fault domains are defined which reflect, either physically or virtually, the topology of a networked computing environment. These defined fault domains are then used to control where cached data is replicated when running in a write back cache mode. Unlike known replication approaches, the present approach replicates such data according to a user's defined data policy and based on the defined fault domains thereby avoiding the user having to keep track of changes in computing system configurations or update their data policy when virtual machines migrate from one host computing system to another.

Abstract: Apparatuses, methods, and systems are configured to perform unambiguous parameter sampling in a heterogeneous multi-core or multi-threaded environment by masking one or more thread requests; and, in response to bus activity ceasing for the one or more masked thread requests and completing any routine being processed for the one or more masked threads, processing a command by executing at least one of a command routine or a command thread, wherein the command routine or the command thread reads the parameter using thread atomicity with deterministic synchronization. One or more thread requests may be selected for masking by monitoring thread activity for each of a plurality of threads.
