Sharing reconfigurable computing devices between workloads

One or more physical RCDs (PRCDs) are shared between one or more workloads in one or more virtual computing environments. Example PRCD sharing operations may include: (1) providing a virtual RCD (VRCD) for one of the workloads, the VRCD being programmed with an IC design representing a hardware implementation of a software hotspot in the workload, (2) allocating one of the PRCDs to the workload by scheduling the programmed VRCD on the PRCD, (3) burning the PRCD with the IC design of the programmed VRCD so that the PRCD becomes a programmed PRCD that is capable of implementing the workload's hotspot in hardware, and (4) invoking the programmed VRCD instead of executing the hotspot as software in order to cause the programmed PRCD to implement the hotspot in hardware.
