Abstract
An operating system resource, configured for establishing communications between consumer processes configured for generating respective work notifications and a host channel adapter configured for servicing the work notifications, assigns virtual address space for use by the consumer processes in executing memory accesses, and respective unique mapping values. An address translator includes a translation map for uniquely mapping the virtual address space used by the consumer processes to a prescribed physical address space accessible by the host channel adapter. The address translator, in response to receiving from an identified consumer process the work notification at a virtual address, maps the work notification to a corresponding prescribed physical address based on the corresponding mapping value assigned to the identified consumer process, enabling the host channel adapter to detect the work notification for the consumer process.
