As a result, redesign involved in changes in system specifications can be reduced, and a malfunction owing to resource contention can be prevented. The invention contributes to increase of security.

A performance prediction simulator gives effect to the resource contention among multiple resources in a simulated system by adjusting event durations appropriately. A resource topology tree defining the resource configuration of the system is input to the simulator. The simulator includes an evaluation engine that determines the amount of resource used during each simulation interval of the simulation and records the resource usage in a resource contention timeline, which can be displayed to a user. The amount of resource used during a simulation is also used to adjust the event duration calculations of the hardware models associated with each event.

Computer processors and methods of operation of computer processors that include a plurality of pipelined hardware threads of execution, each thread including a plurality of computer program instructions; an instruction decoder that determines dependencies and latencies among instructions of a thread; and an instruction dispatcher that arbitrates, in the presence of resource contention and in accordance with the dependencies and latencies, priorities for dispatch of instructions from the plurality of threads of execution.

Monitoring is performed to detect a hang condition. A timer is set to detect a hang based on a core hang limit. If a thread hangs for the duration of the core hang limit, then a core hang is detected. If the thread is performing an external memory transaction, then the timer is increased to a longer memory hang limit. If the thread is waiting for a shared resource, then the timer may be increased to the longer memory hang limit if another thread or, more particularly, the thread blocking the resource has a pending memory transaction. Responsive to detecting a hang condition, instructions dispatched to the plurality of execution units may be flushed, or the processor may be reset and restored to a previously known good, checkpointed architected state.

A method for determining where in time to schedule a project in a computerized system for scheduling multiple projects operates in conjunction with a database composed of schedules for individual projects with resources assigned to some tasks. A user specifies the resources to be used for a new project, the loading caused by projects whose dates are already determined, the earliest possible start times for the new project, and the maximum amount of expansion in flow time (start to finish time) allowed for the new project, with considering inter-project resource contention. The new project is delayed only long enough to allow contention for the selected resources to be resolved, while not violating the flow time expansion restriction.

Under a resource manager, unexpected blocking is prevented without calling a handler for resolving a resource contention, by assigning a priority level depending on the program that has requested for a reservation of a resource as well as by assigning a special priority level which permits a reservation of a resource without any conditions in the case of a program which is urgently needed such as an EAS module.

The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.

When a process sleep event, a process wake-up event, a process save event, and a process resume event occur in an IT system having a multiprocessor configuration, a tracer respectively generates sleep event data, wake-up event data, save event data, and resume event data and records them as trace data in a trace buffer. The analysis unit generates an analysis result by referring to the trace data to accumulate a number of times of execution of the process wake-up process and a first time as a time from the process save event to the process wake-up event or to the process resume event with respect to a plurality of processes to be executed. When a contention for a shared resource occurs, the process wake-up process is repeatedly executed among relevant processes. For this reason, based on the analysis result, a possibility can be presented that the shared resource contention occurs in the IT system.

Execution of a computer program on a multiprocessor system is monitored to detect possible excess parallelism causing resource contention and the like and, in response, to controllably limit the number of processors applied to parallelize program components.

A multi-threaded processor is configured to detect excepted instructions from a first program, and to stop fetching younger instructions from that same program, to thereby conserve system resources that can be used by other programs. Each fetched program instruction has an associated status bit, which is set if the instruction excepts. Each excepting instruction is logged in an exception logging unit, which causes the associated status bit to be set. Each program has an associated in-flight vector table that tracks the instructions that have been fetched for that program. The status bits are compared with the in-flight vector table to identify the program that is associated with an excepted instruction. That program is then disabled, thereby preventing further fetching of instructions for that program until the excepted instruction clears.

To facilitate both minimal allocations and adaptive allocations, two sets of storage group policies are defined—one policy setting minimal allocation values for storage group access to storage resources and one policy setting maximal allocation values for storage group access to storage. In addition, a set of priority weights is specified that is used to balance access to storage tiers across storage groups. Upon existence of contention for storage resources, minimum allocation values for storage groups are determined based on the priority weights for the storage groups, resulting in threshold values being set to enable at least partial access to storage resources for all storage groups without requiring priority weighting of the activity density distributions of the competing storage groups. Allocations other than the minimal allocations are provided based on relative activity density distribution of storage extents between groups.

Techniques are disclosed relating to resource contention resolution in a pre-memory environment.

The resource control processing element may respond to the requests by retrieving the requested information from the controller and providing that information to the processing element or by retrieving the requested information from a cache and providing that information to the processing element.
