US 9,317,334 B2 · Multilevel multipath widely distributed computational node scenarios

Abstract

An application combines on-site and cloud-based calculations. The application selects a cloud computing broker from a list sorted by load. The broker receives computation requests from the application, sends corresponding load-balanced requests to local application service hosts and cloud proxies, receives responses, and sends the responses to the application without identifying the response source as local versus non-local. Each proxy has a logical-physical mapping of cloud-resident worker nodes. A scheduler receives session requests from applications, allocates local and cloud computing resources to a session, and tracks resource usage by session. An application previously run only on-premises can be executed partially on cloud worker nodes without modification. The proxy re-routes unfulfilled requests from a failed worker, undetected by the broker. If all workers assigned to that proxy fail, then the broker reassigns unfulfilled requests to another proxy, undetected by the application.

Dependent claims

A multilevel multipath widely distributed computational node system comprising:

at least one broker node having an application request-response interface, at least one application service host interface, and at least one wide distribution proxy interface, the broker node also having a logical processor and a memory in operable communication with the logical processor;
and
a premises transparency code residing in the memory and having a request store and a load-balancing mechanism, the premises transparency code configured to receive requests into the request store through the application request-response interface, to send corresponding load-balanced computation requests to local nodes through the application service host interface(s) and to non-local nodes through the wide distribution proxy interface(s) based on a prior allocation of local and widely distributed node computational resources by a node other than the broker node, to receive computation responses from local nodes through the application service host interface(s) and from non-local nodes through the wide distribution proxy interface(s), and to send the computation responses through the application request-response interface without thereby identifying the source of the computation responses as being from a local node versus a non-local node.

A computer-readable distributed storage medium configured with data and with instructions that when executed by processors cause the processors to perform a process for process for multilevel multipath widely distributed computational node management, the process comprising the steps of:

a broker node receiving multiple requests from an application node;
the broker node sending corresponding computation requests to wide distribution proxy node(s), and to local nodes, which were previously allocated by a head node;
the wide distribution proxy node(s) receiving computation requests from the broker node, sending the computation requests to widely distributed worker nodes, receiving computation responses from the widely distributed worker nodes, and sending the computation responses to the broker node without thereby identifying any particular widely distributed worker node as the source of a given computation response;
the broker node receiving computation responses from the wide distribution proxy node(s) and the local nodes;
and
the broker node sending the computation responses to the application node without thereby identifying the source of the computation responses as being from a local node versus a widely distributed worker node.
