Abstract: An apparatus, program product and method to manage access to a shared resource by a plurality of processes in a multithreaded computer via a collection of atomic operations that track both the order in which requests that use a shared resource are received, and the order in which processing of such requests are completed after they are received. Dispatching of requests is effectively deferred until processing of all non-dispatched requests that were received earlier than a most recently completed request has been completed. In many instances, completion of processing of requests can be performed non-atomically, thus reducing contention issues with respect to the shared resource. Furthermore, dispatching of requests may be batched to reduce the overhead associated with individual dispatch operations.

Abstract translation: 一种用于通过多个线程计算机中的多个进程通过收集跟踪使用共享资源的请求的顺序的原子操作的集合来管理对共享资源的访问的装置，程序产品和方法，以及其中 这些请求的处理在收到之后完成。 有效地推迟请求的调度，直到处理在最近完成的请求之前接收到的所有未发送的请求已经完成。 在许多情况下，可以非原子地执行请求的处理完成，从而减少对共享资源的争用问题。 此外，可以批量发送请求以减少与各个调度操作相关联的开销。

Abstract: Migrating a logical partition (LPAR) from a first physical port to a first target physical port, includes determining a configuration of an LPAR having allocated resources residing on a computer and assigned to the first physical port of the computer. The configuration includes a label that specifies a network topology that is provided by the first physical port and the first target physical port has a port label that matches the label included in the configuration of the LPAR. The first target physical port with available capacity to service the LPAR is identified and the LPAR is migrated from the first physical port to the target physical port by reassigning the LPAR to the first target physical port.

Abstract: Das Verlagern einer logischen Partition (LPAR) von einem ersten physischen Anschluss zu einem ersten physischen Zielanschluss beinhaltet das Ermitteln einer Konfiguration einer LPAR, der auf einem Computer befindliche Ressourcen zugeordnet sind und der der erste physische Anschluss des Computer zugewiesen ist. Die Konfiguration enthält eine Kennzeichnung, die eine Netzwerktopologie angibt, die durch den ersten physischen Anschluss bereitgestellt wird, und der erste physische Anschluss weist eine Anschlusskennzeichnung auf, die mit der Kennzeichnung übereinstimmt, die in der Konfiguration der LPAR enthalten ist. Der erste physische Zielanschluss mit einer verfügbaren Kapazität zum Versorgen der LPAR wird ermittelt, und die LPAR wird von dem ersten physischen Anschluss zu dem physischen Zielanschluss verlagert, indem die LPAR dem ersten physischen Zielanschluss neu zugewiesen wird.

Dispatching of requests is effectively deferred until processing of all non-dispatched requests that we re received earlier than a most recently completed request has been completed. In many instances, completion of processing of requests can be performed non- atomically, thus reducing contention issues with respect to the shared resource. Furthermore, dispatching of requests may be batched to reduce the overhead associated with individual dispatch operations.
