摘要： Aspects of the subject matter described herein relate to modeling and simulating software contention. In aspects, a model declares properties of a scarce software object and models software components that need the scarce software object to execute. A simulator uses the model to set up data structures that track locking activity related to the software object. The simulator simulates the interaction between software components and hardware including seizing and releasing locks on the software object. The simulator may use a function or other similar mechanism to distribute seize and release operations with respect to a lock across multiple instances of the software object. The simulator may use data generated by a simulation to provide an indication of lock objects and hardware utilization, transaction latencies, and other statistics.

摘要： Simulating an application. A method that may be practiced in a computing environment configured for simulating an application modeled by an application model deployed in a performance scenario of a computing system by deploying service models of the application model to device models modeling devices. The method includes referencing a performance scenario to obtain a transaction being modeled as originating from a first device model. The transaction invokes of a first service model. The first service model specifies hardware actions for simulation. The first service model is referenced to determine the hardware actions for simulation and the next referenced service. The next referenced service specifies hardware actions to be added to the transaction and may specify invocation of other service models. A chain of hardware actions is generated by following the invocation path of the service models. The hardware actions are applied to device models to simulate the transaction.

摘要： Simulating device interactions. A method may be practiced in a computing system for simulating interconnected devices. The method of simulating device interactions may be done in performing an overall transaction to obtain an output of system performance characteristics including measurement of latencies and/or device loads for actions performed by devices in performing the overall transaction. The method includes dividing a transaction into individual actions. The actions are applied to appropriate device models to produce latencies and/or device utilizations for the action as applied to the appropriate device model. This may be done by including an indication of an action type and optionally an action subservice. Memory resources may be conserved by ending the simulation when latencies and/or device utilizations have settled. Device utilization and latency may be aggregated and averaged over time. When changes in the latencies and/or device utilizations are within a predetermined range, the simulation can be ended.

摘要： Preconditioning for stochastic simulation of computer system performance is described. In an embodiment, methods taught herein include preconditioning a performance scenario that is simulated as part of a software deployment. The performance scenario specifies devices included as part of a hardware configuration supporting the software. The performance scenario can be modified based, at least in part, on the result of the preconditioning. Other methods taught herein include two complementary techniques for preconditioning performance scenarios, referred to as pseudo-simulation and workload aggregation.

摘要： A method includes determining a total storage input/output capacity of a set of storage elements available for use by a software application located on an operating system volume of a computer system. The total storage input/output capacity is determined by evaluating storage input/output capacity of the storage elements at a physical device level and at a file level. The method includes measuring a number of input/output storage operations performed on behalf of the software application. The method also includes determining a storage input/output utilization of the software application based on the measured number of input/output storage operations as compared to the total storage input/output capacity of the set of storage elements.
