Runtime Virtualization of Reconfigurable Data Flow Resources

A system, comprising:

• a plurality of reconfigurable devices, reconfigurable devices in the plurality of reconfigurable devices including a plurality of reconfigurable processors, reconfigurable processors in the plurality of reconfigurable processors including an array of configurable units, and the array of configurable units partitionable into a plurality of subarrays of configurable units;
• data;
• a plurality of transfer resources usable by the reconfigurable devices to receive and send a plurality of storage resources usable by the reconfigurable devices to store data;
• and
• a runtime processor configured with logic to
• present a unified interface to the plurality of reconfigurable devices, the plurality of transfer resources, and the plurality of storage resources;
• control execution of a plurality of application graphs based on an execution file, the execution file including configuration files for application graphs in the plurality of application graphs, topologies of subarrays of configurable units in the plurality of subarrays of configurable units required to load and execute the configuration files, and resource requests for transfer resources in the plurality of transfer resources and storage resources in the plurality of storage resources required to satisfy data and control dependencies of the application graphs;
• allocate the subarrays of configurable units to the application graphs based on the topologies;
• allocate the transfer resources and the storage resources to the application graphs based on the resource requests;
• and
• load and execute the configuration files using the allocated subarrays of configurable units, transfer resources, and storage resources.
