Abstract

Shared resources have availability and operability dependent on a plurality of conditions, such as free space in a storage device. These conditions must be known to all processors in a multiprocessing environment. Efficiency of the installation is enhanced by having one of the processors, and only one of the processors, scan the shared resources for developing status information concerning selective conditions, such as free space. The one processor then broadcasts the accumulated information to all of the other processors. This eliminates the need for all of the processors to sense the shared resources for developing condition information. Provisions are made for recovery from the one processor failure, such that the multiprocessing installation operability is not dependent upon a single processor.
