Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 11/00

US Classification:

714 48

Abstract:

A cellular computer system is constructed of a plurality of cells. Each cell has a memory system, a plurality of processors capable of accessing the memory system, a system communication interface coupled to processors, and a cell error queue maintained by a processor within the memory system. The system communication interface of each cell is coupled to other cells of the system. A first cell of the plurality of cells is a master cell that maintains a partition error queue and is capable of receiving into the partition error queue error descriptors from the cell error queue of a second cell of the plurality of cells.

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 12/00

US Classification:

711209, 719328

Abstract:

System and method of supporting virtual mappings for shared firmware contents in a computer system are described. In one embodiment, the method comprises, responsive to a function call issued by a processor, determining whether address translation has been enabled for the issuing processor; and responsive to a determination that address translation has been enabled, determining an ID of the issuing processor; identifying a Physical-to-Virtual (“PTV”) Map corresponding to the issuing processor; extracting from the identified PTV map a virtual address corresponding to a physical address passed in the function call; and returning the virtual address to the issuing processor.
