An apparatus, program product and method dynamically assign threads to computer resources in a multithreaded computer including a plurality of physical subsystems based upon specific “types” associated with such threads. In particular, thread types are allocated resources that are resident within the same physical subsystem in a computer, such that newly created threads and/or reactivated threads of those particular thread types are dynamically assigned to the resources allocated to their respective thread types. As such, those threads sharing the same type are generally assigned to computer resources that are resident within the same physical subsystem of a computer, which often reduces cross traffic between multiple physical subsystems resident in a computer, and thus improves overall system performance.

Disclosed is an apparatus, method, and program product for observing the nodal workload balance of the system on an ongoing basis, and for dynamically changing the preferred nodes of existing threads in order to improve nodal balance. Workload balance is ascertained on a nodal basis and then thread-based workload information is collected. If the detected imbalance persists, the thread-based information is used to change the assignment of preferred nodes to threads to improve nodal workload balance.

An apparatus, program product and method in which application program-specified resource allocation and allocation strength preferences are used to allocate hardware resources from a computer for that application program. The resource allocation preference is used to allocate hardware resources for the application program, while the allocation strength preference is used to determine whether to allocate alternate hardware resources when the resource allocation preference specified by the application program cannot be met.

Method for measuring the performance of a multi-nodal computer system. In one embodiment, a number of system related events may be instrumented. When an instrumented event occurs, instrumentation routines may be invoked to record the state of system variables related to the event. In particular, events such as thread creation, dispatch, and nodal events such as events related to verifying or changing workload distribution in a multi-nodal system, among others, may be instrumented to record the state of variables as these events occur in a running multi-nodal computer system.

Diagnostic data, such as a time increment corresponding to how long a thread waits to access a shared resource, is stored within a predetermined location in a data structure, such as a hash bucket in a hash table. The location is preferably correlated to the resource such that a display of the diagnostic data may be tailored to reflect a user-specified relationship between the data and resource.

Mechanism for Assigning Home Nodes to Newly Created Threads Disclosed is an apparatus, method, and program product for associating threads with the processing nodes of a multi-nodal computer system. The assignment is accomplished by considering both the relative work capacity of, and the relative amount of ongoing work assigned to, each node. Initiation Weights are used in the preferred embodiment to reflect the desired proportions of threads assigned to each node, from the standpoint of which node should be chosen when a new thread is created.
