Managing cloud-based hardware accelerators

Abstract:

A cloud-based accelerator manager manages cloud-based hardware accelerators. The accelerator manager monitors computer programs running in the cloud and generates a trace that indicates which accelerators were used and when. The trace may be for a single computer program or may be for multiple computer programs. Thus, the trace can be program-specific, showing all accesses to accelerators by a single program, or may be accelerator-specific, showing all accesses to each accelerator by all computer programs. The cloud-based accelerator manager detects a failure in one of the computer programs executing in the cloud. The cloud-based accelerator manager provides the trace to a user, who can then analyze the trace to determine whether the failure was due to an accelerator. The cloud-based accelerator manager thus helps detect when cloud-based accelerators are the reason for failures for computer programs running in a cloud.
