Abstract

Processing within a computing environment is facilitated by filtering requests of the computing environment. A processing unit that receives a request determines whether it is to perform the request. This determination is made by, for instance, comparing an identifier of the request with an identifier of the processing unit making the determination. If there is a mismatch, then the request is blocked. Other processing within the computing environment is also facilitated by selectively using buffer entries. The selection criteria is based, for instance, on identifier information.
