Prioritized polling techniques

A non-transitory computer readable medium comprising code stored thereon that, when executed, performs a method comprising:

• for a first plurality of services, assigning each service of the first plurality a polling priority of a non-critical polling priority or a critical polling priority, wherein each service of the first plurality is associated with a corresponding service queue set of a second plurality of service queue sets of a local node, wherein each service queue set of the second plurality of service queue sets associated with a corresponding service of the first plurality includes a completion queue (CQ) and an associated receiving queue (RQ) of work queue entries (WQEs) associated with received messages that are stored in a first memory of the local node and sent by a remote node via remote direct memory access (RDMA);
• partitioning CQs of the second plurality of service queue sets associated with the first plurality of services in accordance with assigned polling priorities to generate a non-critical CQ list of the local node and a critical CQ list of the local node, wherein the non-critical CQ list includes CQs associated with services of the first plurality assigned the non-critical polling priority, and wherein the critical CQ list includes CQs associated with services of the first plurality assigned the critical polling priority;
• polling each CQ of the non-critical CQ list on the local node by a non-critical poller at a non-critical polling frequency, wherein said polling said each CQ of the non-critical CQ list includes polling said each CQ of the non-critical CQ list for completion signals or indicators associated with corresponding received non-critical messages of the local node to be serviced;
• and
• polling each CQ of the critical CQ list on the local node by a critical poller at a critical polling frequency, wherein said polling said each CQ of the critical CQ list includes polling said each CQ of the critical CQ list for completion signals or indicators associated with corresponding received critical messages of the local node to be serviced.

A system comprising:

• one or more processors;
• and
• a memory comprising code stored thereon that, when executed, performs a method comprising:
• for a first plurality of services, assigning each service of the first plurality a polling priority of a non-critical polling priority or a critical polling priority, wherein each service of the first plurality is associated with a corresponding service queue set of a second plurality of service queue sets of a local node, wherein each service queue set of the second plurality of service queue sets associated with a corresponding service of the first plurality includes a completion queue (CQ) and an associated receiving queue (RQ) of work queue entries (WQEs) associated with received messages that are stored in a first memory of the local node and sent by a remote node via remote direct memory access (RDMA);
• partitioning CQs of the second plurality of service queue sets associated with the first plurality of services in accordance with assigned polling priorities to generate a non-critical CQ list of the local node and a critical CQ list of the local node, wherein the non-critical CQ list includes CQs associated with services of the first plurality assigned the non-critical polling priority, and wherein the critical CQ list includes CQs associated with services of the first plurality assigned the critical polling priority;
• polling each CQ of the non-critical CQ list on the local node by a non-critical poller at a non-critical polling frequency, wherein said polling said each CQ of the non-critical CQ list includes polling said each CQ of the non-critical CQ list for completion signals or indicators associated with corresponding received non-critical messages of the local node to be serviced;
• and
• polling each CQ of the critical CQ list on the local node by a critical poller at a critical polling frequency, wherein said polling said each CQ of the critical CQ list includes polling said each CQ of the critical CQ list for completion signals or indicators associated with corresponding received critical messages of the local node to be serviced.
