Proxy queue pair for offloading

A host channel adapter (HCA) for offloading, comprising:

• a proxy central processing unit;
• a receive module for:
• receiving a first work request identifying a first queue pair (QP), wherein the first QP is associated with an application executing on a host connected to the HCA;
• making a first determination that the first QP is a proxy QP;
• redirecting the first work request to the proxy CPU on the HCA based on the first determination and based on the first work request satisfying a filter criterion;
• receiving a second work request identifying the first QP;
• and
• processing the second work request without redirecting to the proxy CPU based on the first determination and based on the first work request failing to satisfy the filter criterion;
• a completion module, stored in a memory and executed by the proxy central processing unit, for:
• generating a first completion for the first work request;
• and
• generating a second completion for the second work request;
• and a descriptor fetch module for:
• redirecting the first completion and the second completion to the proxy CPU based on the first determination,
• wherein the proxy CPU processes the first work request, the first completion, and the second completion.

A system comprising:

• a host comprising a memory, a central processing unit, and an application;
• and
• a host channel adapter (HCA), connected to the host, for:
• receiving a first work request identifying a queue pair (QP), wherein the
• QP is associated with the application;
• making a first determination that the QP is a proxy QP;
• offloading the first work request to a proxy central processing unit (CPU) based on the first determination and based on the first work request satisfying a filter criterion;
• receiving a second work request identifying the QP;
• processing the second work request without offloading based on the QP being a proxy QP and based on the first work request failing to satisfy the filter criterion;
• redirecting a first completion for the first work request and a second completion for the second work request to the proxy CPU based on the first determination;
• and
• processing, by the proxy CPU, the first completion and the second completion in order.
