Abstract: A social analytic system collects signals from different social network accounts. Social metrics are derived for the accounts and the accounts classified as different types of constituents for a company or primary account based on the social metrics. The constituents may include any combination of advocates, detractors, influencers, spammers, employees, partners, and/or market. Some of the social metrics used for classifying the different types of constituents may include a volume of the signals, types of message interactions, number of unique messages, sentiment, number of subscribers, alignment of constituent and company messages, and/or average signal length.

Abstract: A social analytic system may collect social signals from different social network accounts. The social signals may be associated with different ecosystems. Time series data may be generated from the social signals and the time series data may be filtered to remove at least some generic or unrelated trends. Different data sets from the time series data may be associated with different ecosystem metrics. The social analytic system may compare different filtered time series data sets to identify different ecosystem events. For example, the comparisons may be used to identify highly correlated ecosystem metrics and ecosystem anomalies, and predict ecosystem events.

Abstract: The present invention relates to an improved microprocessor having a memory system with several caches that can be operated to provide virtual memory. Among the caches included in the microprocessor are conventional caches that store data and instructions to be utilized by the processes being performed by the microprocessor, and that are typically arranged in a cache hierarchy, as well as one or more translation lookaside buffer (TLB) caches that store a limited number of virtual page translations. The improved microprocessor also has an additional cache that serves to store a virtual hash page table (VHPT) that is accessed when TLB misses occur. The introduction of this VHPT cache eliminates or at least reduces the need for the microprocessor to look for information within the caches of the cache hierarchy or in other memory (e.g., main memory) outside of the microprocessor when TLB misses occur, and consequently enhances microprocessor speed.

Abstract: An apparatus for communicating between lock step is incorporated on two or more processors operating in a lock step mode. Each of the processors includes processor logic to execute a code sequence, and an identical code sequence is executed by the processor logic. The apparatus further includes a processor-specific resource referenced by the code sequence. A multiplexer is coupled to the processor-specific resource, and is controlled to read data based on the identification. Coupled to the processors is a lock step logic block operable to read and compare the output of each of the processors. The lock step logic determines if operation of the processors is in a lock step mode or in an independent processor mode. Such determination may be made by the lock step logic turning off, for example.
