Abstract: An example method includes (a) generating a request to obtain log data descriptive of operation of an autonomous vehicle control system in a subject scenario, the log data indexed by an indexing parameter; (b) submitting the request to a log repository service, the log repository service configured to receive the request and serve, responsive to the request, log metadata; (c) loading, based on the log metadata and an index value of the indexing parameter, a log data sketch associated with the index value; and (d) loading, based on the log metadata and the index value, and responsive to an inspection indicator, detailed log data associated with the index value.

Abstract: A method is disclosed for selecting from among a plurality of computer processors connected together to distribute portions of an overall numerical problem to be solved among the processors to optimize the speed of communication between the processors in solving the overall problem. The method utilizes various factors in determining the selection, including whether any of the processors are located within the same computer or workstation, whether any of the processors share a network switch, whether any of the processors are located on the same sub-network, the speed of the individual network connections, and any user-configurable groupings of the processors. Also considered are the known communication requirements of the problem to be solved. A simulated annealing algorithm is then used to determine the optimal arrangement of the processors in solving the problem.
