Abstract: In a method an Intelligent Data Conversion (IDC) engine of a dataflow system detects a stage transition of a dataflow application executing on the dataflow system. In response, the IDC engine determines that data among stage data of the application has a first Stage Data Format (SDF). The IDC engine determines that a first processing unit of the dataflow system can process data having a second SDF and determines a data conversion to convert data among the stage data to have the second SDF. The IDC engine also determines a second processing unit, of the dataflow system to perform the data conversion and dispatches the second processing unit to perform the data conversion. The dataflow computing system can include a runtime processor and the IDC engine can interact with the runtime processor to detect the stage transition and/or dispatch the first processing unit.

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.
