Dynamic reconfiguration imposes significant penalties in terms of performance and energy. Scheduling the execution of tasks on a dynamically reconfigurable device is therefore of critical importance. Likewise, other application domains have cost models that are effectively the same as dynamic reconfiguration; examples include: data transmission across multiprocessor systems; dynamic code updating and reprogramming of motes in sensor networks; and module allocation, wherein the sharing of resources effectively eliminates inherent reconfiguration costs. This paper contributes a fully polynomial time approximation algorithm for the problem of scheduling independent tasks onto a fixed number of heterogeneous reconfigurable resources, where each task has a different hardware and software latency on each device; the reconfiguration latencies can also vary between resources.
