Abstract: Approaches for managing how the passage of time is observed by a software execution environment, such as a virtual machine or a sandbox environment. A computer system maintains a set of physical time sources. A set of virtual time sources are computed based on the set of physical time sources. The virtual time sources operate independently of the set of physical time sources. For example, the virtual time sources may observe time passing faster or slower than the set of physical time sources. The set of virtual time sources are presented to the software execution environment as the set of time sources. Many benefits may be obtained such as higher utilization of allocated resources and avoidance of timeouts.

Abstract: Roughly described, a task control system for managing multi-scale simulations receives a case/task list which identifies cases to be evaluated, at least one task for each of the cases, and dependencies among the tasks. A module allocates available processor cores to at least some of the tasks, constrained by the dependencies, and initiates execution of the tasks on allocated cores. A module, in response to completion of a particular one of the tasks, determines whether or not the result of the task warrants stopping or pruning tasks, and if so, then terminates or prunes one or more of the uncompleted tasks in the case/task list. A module also re-allocates available processor cores to pending not-yet-executing tasks in accordance with time required to complete the tasks and constrained by the dependencies, and initiates execution of the tasks on allocated cores.

Abstract: Performance of parallel portions of a streaming application implemented in multiple virtual machines (VMs) is monitored and logged. When there is a need to replicate operators in an existing virtual machine to a new virtual machine, the logged performance data is used to determine a desired configuration for the new virtual machine based on a past implementation of the existing virtual machine.

Abstract: Systems and methods are described for implementing a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinator can be provisioned with a set of tasks, each task corresponding to a segment of code that can be executed by the coordinator, such as to manage the coordinated devices. To assist in execution of the tasks, the coordinator can include a resource manager that generates execution environments corresponding to an individual task execution, which environments may be isolated from other execution environments. The coordinator can further include a scheduler to obtain calls to execute tasks, and implement a queue from which to select tasks for execution. On selecting a task, the scheduler may interact with the resource manager to generate an execution environment for the task, and cause execution of the task within the execution environment.

Abstract: A method and system. A library method stub is created in a predefined programming language by use of a library method signature associated with an original library call, at least one idiom sentence, and a call invoking the original library call. Creating the library method stub includes composing source code of the library method stub by matching the at least one idiom sentence with idiom-stub mappings predefined for each basic idiom of at least one basic idiom. The original library call appears in sequential code. The library method signature specifies formal arguments of the original library call. The at least one idiom sentence summarizes memory operations performed by the original library call on the formal arguments. The created library method stub is stored in a database.

Abstract: A system and method are disclosed for receiving a request for resources in a compute environment to process workload, the request including a specification of a quality of fit. The system generates a substantial maximum potential quality of fit based on compute environment with an assumption of no competing workload to yield an analysis. The system evaluates a first resource allocation and a second resource allocation against the analysis to yield the first fit in a respective second fit. The system selects one of the first resource allocation and the second resource allocation based on a comparison of the first fit to the second fit as well as a cost associated with any delays.

Abstract: A processor may comprise a plurality of cores operating at heterogeneous frequencies communicatively coupled by a network of routers also operating at heterogeneous frequencies. A core may be prioritized for thread execution based on operating frequencies of routers on a path from the core to a memory controller. Relatively higher priority may be assigned to cores having a path comprising only routers operating at a relatively higher frequency. A combined priority for thread execution may be based on core frequency, router frequency, and the frequency of routers on a path from the core to a memory controller. A core may be selected based primarily on core operating frequency when cache misses fall below a threshold value.

Abstract: Techniques for providing high-performance buffer caches for transactional input/output (I/O) systems are disclosed. The techniques include obtaining a first logical creation time of a resource to be acquired by the first transaction during a pre-commit phase of a first transaction with an I/O system. When the first logical creation time exceeds a latest logical creation time from a set of resources previously acquired by the first transaction, the first logical creation time of the resource is compared with an earliest logical termination time from the set of resources. When the first logical creation time of the resource exceeds the earliest logical termination time from the set of resources, a conflict between the resource and the set of resources is detected, and a restart of the first transaction is triggered.

Abstract: A computer system, method, and computer readable product are provided for identifying and isolating library code that has been obfuscated in software applications. A call graph is created for the execution of at least one module of preexisting library code within a bundle of software modules through either static analysis of the software code or dynamic analysis of the executing code, and then one or more anchor points are devised based upon the call graph that are indicative of the preexisting library code. Then a bundle of software modules can be analyzed or its execution monitored to determine if a discrete module of library code is present in the executing bundle based upon the modules' interaction with the one or more anchor points, and the discrete module of library code in the executing bundle can be identified as a module of preexisting library code.
