Abstract: Queuing of received transactions that have a resource conflict is disclosed. A first node receives a first transaction from a second node, where the first transaction relates to a resource of the first node. The transaction may be a request relating to a memory line of the first node, for instance. It is determined that a second transaction that relates to this resource of the first node is already being processed by the first node. Therefore, the first transaction is enqueued in a conflict queue within the first node. The queuing may be a linked list, a priority queue, or another type of queue. Once the second transaction has been processed, the first transaction is restarted for processing by the first node. The first transaction is then processed by the first node.

Abstract: According to one aspect of the present disclosure a method and technique for managing memory access is disclosed. The method includes setting a memory databus utilization threshold for each of a plurality of processors of a data processing system to maintain memory databus utilization of the data processing system at or below a system threshold. The method also includes monitoring memory databus utilization for the plurality of processors and, in response to determining that memory databus utilization for at least one of the processors is below its threshold, reallocating at least a portion of unused databus utilization from the at least one processor to at least one of the other processors.

Abstract: The temporary storage of a memory line to be stored in a cache while waiting for another memory line to be evicted from the cache is disclosed. A method includes evicting a first memory line currently stored in the cache and storing a second memory line not currently stored in the cache in its place. While the first memory line is being evicted, such as by first being inserted into an eviction queue, the second memory line is temporarily stored in a buffer. The buffer may be a data transfer buffer (DTB). Upon eviction of the first memory line, the second memory line is moved from the buffer into the cache.

Abstract: Non-inline transaction error correction is disclosed. Where a transaction being processed in a pipeline is determined to include a correctable error, it is output, or drained, from the pipeline into an error queue. The pipeline is switched from a normal mode of operation to a correction mode of operation. In the correction mode, a correction command is inserted into and processed within the pipeline to correct the error within the transaction. The pipeline is switched from the correction mode of operation to a restart mode of operation. In the restart mode, the transaction is reprocessed within the pipeline. The pipeline is then switched from the restart mode of operation back to the normal mode of operation.

Abstract: A job scheduler can select a processor core operating frequency for a node in a cluster to perform a job based on energy usage and performance data. After a job request is received, an energy aware job scheduler accesses data that specifies energy usage and job performance metrics that correspond to the requested job and a plurality of processor core operating frequencies. A first of the plurality of processor core operating frequencies is selected that satisfies an energy usage criterion for performing the job based, at least in part, on the data that specifies energy usage and job performance metrics that correspond to the job. The job is assigned to be performed by a node in the cluster at the selected first of the plurality of processor core operating frequencies.

Abstract: Partitioning a node of a multi-node system into more than one partition is disclosed. First resources of the node are physically partitioned into more than one partition. The first resources physically partitioned to each partition are directly inaccessible by other partitions of the node. Second resources of the node are then internally logically partitioned into the more than one partition. Each second resource internally separates transactions of one partition from transactions of other partitions. Furthermore, the node can be dynamically repartitioned into other partitions, such as a single partition, without having to take the multi-node system down. Operating system (OS) instances of the partitions may have assumptions provided to allow for dynamic partitioning, such as quiescing the processors and/or the input/output components being reconfigured, purging remote cache entries across the entire OS, etc. Each partition may have associated therewith registers that are protected from access by other partitions.
