摘要： Mechanisms are provided for processing streaming data at high sustained data rates. These mechanisms receive a plurality of data elements over a plurality of non-sequential communication channels and write the plurality of data elements directly to the file system of the data processing system in an unassembled manner. The mechanisms determining whether to perform a data scrubbing operation or not based on history information indicative of whether data elements in the plurality of data elements are being received in a substantially sequential manner. The mechanisms perform a data scrubbing operation, in response to a determination to perform data scrubbing, to identify any missing data elements in the plurality of data elements written to the tile system and assemble the plurality of data elements into a plurality of data streams in response to results of the data scrubbing indicating that there are no missing data elements.

摘要： An addressing model is provided where all resources, including memory and devices, are addressed with internet protocol (IP) addresses. A task, such as an application, may be assigned a range of IP addresses rather than an effective address range. Thus, a processing element, such as an I/O adapter or even a printer, for example, may also be addressed using IP addresses without the need for library calls, device drivers, pinning memory, and so forth. This addressing model also provides full virtualization of resources across an IP interconnect, allowing a process to access an I/O device across a network.

摘要： A mechanism is provided for managing a process-to-process inter-cluster communication request. A call from a first application is received in a first operating system in a first data processing system. The first operating system passes the call from the first operating system to a first host fabric interface controller in the first data processing system without processing the call. The first host fabric interface processes the call to determine a second data processing system in the plurality of data processing systems with which the call is associated, wherein the call is processed by the first host fabric interface without intervention by the first operating system. The first host fabric interface initiates an inter-cluster connection to a second host fabric interface in the second data processing. The call is then transferred to the second host fabric interface in the second data processing system via the inter-cluster connection.

摘要： A barrier synchronization register, accessible to the nodes in a distributed data processing system, has portions thereof allotted to threads which are present in multiple groups. The barrier synchronization register portion allotted to a given thread has stored therein, over time, group identifier numbers. In this way the state space of a barrier synchronization register is shared over more than one group of process threads.

摘要： In a multinode data processing system in which nodes exchange information over a network or through a switch, a structure and mechanism is provided within the realm of Remote Direct Memory Access (RDMA) operations in which DMA operations are present on one side of the transfer but not the other. On the side in which the transfer is not carried out in DMA fashion, transfer processing is carried out under program control; this is in contrast to the transfer on the DMA side which is characteristically carried out in hardware. Usage of these combination processes is useful in programming situations where RDMA is carried out to or from contiguous locations in memory on one side and where memory locations on the other side is noncontiguous. This split mode of transfer is provided both for read and for write operations.

摘要： A mechanism is provided for managing an input/output device communication request. A first operating system passes a call from a first application intended for an input/output device in a second data processing system to a first host fabric interface controller in the first data processing system without processing the call. The first host fabric interface processes the call to determine the second data processing system with which the call is associated. The first host fabric interface initiates a connection to a second host fabric interface in the second data processing system and transfers the call to a second operating system associated with the input/output device in the second data processing system via the connection to the second host fabric interface. The second operating system then processes the call intended for the input/output device without assistance from any application running on the second data processing system.
