Abstract

See full text

A computer-implemented method, according to one embodiment, includes: receiving an I/O queue creation request, and identifying a first CPU core that can satisfy the I/O queue creation request. A determination is made as to whether the first CPU core already has an I/O queue formed thereon. In response to determining that the first CPU core already has an I/O queue formed thereon, a determination is made as to whether any CPU cores do not already have an I/O queue formed thereon. In response to determining that each CPU core already has an I/O queue formed thereon, the host is informed that satisfying the I/O queue creation request will cause an overlap with existing I/O queues. In response to receiving an indication from the host to satisfy the I/O queue creation request despite the overlap, instructions are sent to use the first CPU core to satisfy the I/O queue creation request.
