Abstract
Diagnostic environments designed for ccNUMA computing systems require different capabilities than conventional diagnostic programs. Since most conventional operating systems do not permit sufficient access to hardware by application programs, a diagnostic microkernal is distributed to all of the processors of all of the nodes of the computing system. Instead of dumping output to a user interface, diagnostic programs executing under control of the diagnostic microkernal store formatted data in shared memory. A shell process executing at an interface node is notified of errors and informs the user who selects the formatted data in shared memory to be accessed by the shell process for output via a user interface by little more than echoing the data. Either a dumb terminal or a desktop computer or workstation which adds further formatting capabilities may be used for display of the data.
