Abstract: A system is presented that includes two data processing systems that are coupled via a network, each data processing system including a reconfigurable processor with a reconfigurable processor memory, a host that is coupled to the reconfigurable processor and that includes a host processor and a host memory that is coupled to the host processor, and a network interface controller (NIC) that is operatively coupled to the reconfigurable processor and to the host processor. The reconfigurable processor of one of the data processing systems is configured to implement a virtual function that uses a virtual address for a memory access operation. An application programming interface (API) in the host processor translates the virtual address into a physical address, and the NIC uses the physical address to initiate a direct memory access operation at the reconfigurable processor memory or the host memory of the other data processing system.

Abstract: A host system for executing an application on first and/or second reconfigurable processors is presented. The host system is operatively coupled to the first and second reconfigurable processors, whereby the first reconfigurable processors have a first architecture, and the second reconfigurable processors have a second architecture that is different than the first architecture. The host system allocates reconfigurable processors of the first and/or second reconfigurable processors for executing the application and includes an auto-discovery module that is configured to determine whether the allocated reconfigurable processors include at least one of the first reconfigurable processors.

Abstract: In a computer-implemented method a Dynamic Transfer Engine (DTE) included in a computing system receives a dynamic stimulus associated with transfer of stage data during execution of a dataflow application by the system. The DTE determines, based on source and destination devices of the transfer, a transfer method and a transfer channel to transfer the stage data between memories coupled to the source and destination devices. The DTE acquires, hardware resources of the computing system to transfer the stage using the channel and, initiates the transfer. A computer program product can cause one or more processors to perform the method. A computing system can comprise source and destination processors and memories, hardware channels to transfer data between the memories, a resource manager, and a DTE configured to perform the method.

Abstract: A data processing system comprises a pool of reconfigurable data flow resources with arrays of physical configurable units, a controller, and a runtime processor. The controller is configured to generate a hot-plug event in response to detecting a removal of an unallocated array of physical configurable units from the pool of reconfigurable data flow resources. The runtime processor is configured to execute user applications on a subset of the arrays of physical configurable units and to receive the hot-plug event from the controller. The runtime processor is further configured to make the removed unallocated array of physical configurable units unavailable for subsequent allocations of subsequent virtual data flow resources and subsequent executions of subsequent user applications, while the subset of the arrays of physical configurable units continues the execution of the user applications.

Abstract: A method of pipelining execution stages of a pipelined application comprises an application execution program (AEP) utilizing a Pipeline Programming Interface (PPI) of a Buffer Pipelined Application computing System (BPAS). In the method the AEP uses one interface of the PPI to determine buffers, among a set of pipeline buffers stored in physical memories of the BPAS, for the BPAS to execute operations a computing application using batches of application data. The AEP uses a second interface of the PPI to load data batches into pipeline buffers, and a third interface of the PPI to input the buffers to the BPAS for executing operations of the application. The AEP can use another interface of the PPI to allocate the buffers in particular physical memories of the BPAS. A computing system can comprise the AEP and BPAS, and can perform the method.

Abstract: A method of pipelining execution stages of a pipelined application can comprise a Buffer Pipeline Manager (BPM) of a Buffer Pipelined Application computing System (BPAS) allocating pipeline buffers, configuring access to the pipeline buffers by stage processors of the system, transferring buffers from one stage processor to a successor stage processor, and transferring data from a buffer in one memory to a buffer in an alternative memory. The BPM can allocate the buffers based on execution parameters associated with the pipelined application and/or stage processors. The BPM can transfer data to a buffer in an alternative memory based on performance, capacity, and/or topological attributes of the memories and/or processors utilizing the memories. The BPM can perform operations of the method responsive to interfaces of a Pipeline Programming Interface (PPI). A BPAS can comprise hardware processors, physical memories, stage processors, an application execution program, the PPI, and the BPM.

The runtime processor is operatively coupled to the pool of reconfigurable data flow resources and configured to load first and second configuration files for executing first and second user applications on first and second subsets of the arrays of physical configurable units and to assign first and second subsets of the memory units to the first and second user applications. The runtime processor starts execution of the first and second user applications on the first and second subsets of the arrays of physical configurable units, prevents the first user application from accessing the resources allocated to the second user application, and prevents the second user application from accessing resources allocated to the first user application.
