In-kernel cache request queuing for distributed cache

A method, comprising:

• executing a kernel of an Operating System (OS) configured to allocate resources of a node;
• using at least a portion of at least one memory of the node as a shared cache in a distributed cache, wherein the distributed cache includes respective shared caches of one or more other nodes on a network;
• and
• creating a plurality of Input/Output (I/O) queues in a kernel space of the at least one memory, wherein each I/O queue of the plurality of I/O queues corresponds to at least one of different respective priorities for requests to access data in the shared cache and different respective applications initiating requests to access data in the shared cache.

A node, comprising:

• at least one memory configured to be used at least in part as a shared cache in a distributed cache;
• a network interface configured to communicate with one or more other nodes in a network, the one or more other nodes each configured to provide a respective shared cache for the distributed cache;
• means for executing a kernel of an Operating System (OS) configured to allocate resources of the node;
• means for receiving, by the kernel, a request to access data in the shared cache of the at least one memory;
• means for identifying an Input/Output (I/O) queue from among a plurality of I/O queues in a kernel space of the at least one memory for queuing the received request for performance based on at least one of a priority indicated by the received request and an application that initiated the request;
• means for executing at least one program in the kernel space of the at least one memory to use data stored in a completion queue in the kernel space to perform at least one computational operation to obtain a result;
• and
• means for providing the result to a user space application.
