Abstract: Systems, methods and article provide the services of heterogeneous resources, for example the services analog processors, e.g., quantum processors, in a robust manner that can include high availability, failover, and load balancing of the heterogeneous resources. A virtual solver is selected based at least in part on a first set of requirements, a first set of analog processors is identified based at least in part on the first set of requirements, and a first handle returned to the first virtual solver. A load balancer may balance loads. Failure over may be implemented.

Abstract: Systems and methods for candidate tracking and fee recovery in accordance with embodiments of the invention are disclosed. In one embodiment, a candidate tracking server system includes a processor and a memory storing a candidate tracking application directing the processor to obtain candidate data describing a candidate, identify at least one publicly available data source system, obtain public activity data for the candidate data from the at least one publicly available data source system, determine current employment status data for the candidate data based on the obtained public activity data, calculate fee opportunity data based on the candidate data, current employment status data, and staffing firm data, determine if the fee opportunity data has been fulfilled, and when the fee opportunity data has not been fulfilled, generate notification data including the fee opportunity data and metadata describing the employer and the staffing firm and provide the generated notification data.
