A method and system for computing a performance forecast for an e-business system or other computer architecture to proactively manage the system to prevent system failure or slow response time. The system is adapted to obtain measured input values from a plurality of internal data sources and external data sources to predict a system's performance especially under unpredictable and dramatically changing traffic levels in an effort to proactively manage the system to avert system malfunction or slowdown. The performance forecasting system can include both intrinsic and extrinsic variables as predictive inputs. Intrinsic variables include measurements of the systems own performance, such as component activity levels and system response time. Extrinsic variables include other factors, such as the time and date, whether an advertising campaign is underway, and other demographic factors that may effect or coincide with increased network traffic.

Methods and systems for enhanced computer performance improve software application execution in a computer system using, for example, a symmetrical multi-processing operating system including OS kernel services in kernel space of main memory, by using groups of related applications isolated areas in user space, such as containers, and using a reduced set of application group specific set of resource management services stored with each application group in user space, rather than the OS kernel facilities in kernel space, to manage shared resources during execution of an application, process or thread from that group. The reduced sets of resource management services may be optimized for the group stored therewith. Execution of each group may be exclusive to a different core of a multi-core processor and multiple groups may therefore execute separately and simultaneously on the different cores.

A remote client computer performance/compatibility querying and certification system allows a server to remotely gather performance/capability information from a client computer, such as its processor class or family, display resolution capability, installed software components, peripheral devices, or the type and version of its operating system, and determine whether it is capable of accessing and utilizing an on-line service via a communication network. The performance/capability information is gathered using a querying program downloaded from the server and running on the client computer. The querying program queries the system/component registry of the client computer's operating system using, e.g., one or more application program interface function calls. The gathered performance/capability information is used to, e.g., pre-certify the client computer before utilizing the on-line service, determine whether the user desires to purchase software on-line, and/or provide an expert technician information regarding the client computer's installed software/hardware components during an on-line technical support session.

A method and system for diagnosing data-processing system performance. Initially, unique audible sounds are associated with particular performance indicators within the data-processing system. Thereafter, performance indicators are identified, one or more of which indicate data-processing system performance. A diagnostic is then periodically run to detect performance indicators within the data-processing system. A unique audible sound is then generated associated with a particular performance indicator, in response to detecting the status of particular performance indicator via the diagnostic, such that potential data-processing system failures may be recognized by identifying the unique audible sound. The unique audible sound may be continuously generated at varying durations and volumes to indicate the presence of system failures. A trained user, accustomed to particular audible sounds, can identify and diagnose system failures by analyzing unique audible sounds generated by the data-processing system. The frequency and duration of each particular sound may be designated and subsequently altered by the user. The performance indicators may be composed of fault modes, one or more of which may presage data-processing system failures. In addition, the data-processing system itself may be composed of a computer system, such as a personal or mainframe computer.

Communication latency, now a dominant factor in computer performance, makes physical size, density, and interconnect proximity crucial system design considerations. The present invention addresses consequential supercomputing hardware challenges: spatial packing, communication topology, and thermal management. A massively-parallel computer with dense, spherically framed, geodesic processor arrangement is described. As a mimic of the problem domain, it is particularly apt for climate modelling. However, the invention's methods scale well, are largely independent of processor technology, and apply to a wide range of computing tasks. The computer's interconnect features globally short, highly regular, and tightly matched distances. Communication modes supported include neighbour-to-neighbour messaging on a spherical-shell lattice, and a radial network for system-synchronous clocking, broadcast, packet-switched networking, and IO. A near-isothermal cooling system, physically divorcing heat source and sink, enables extraordinarily compact geodes with lower temperature operation, higher speed, and lower power consumption.
