Abstract: The inventive multiple partition computer system allows the reconfiguration of the installed hardware, possibly while the various partitions continue normal operations. This aspect includes adding and removing process cell boards and I/O from partitions which may or may not continue to run. The invention also allows changes to the association between cells, I/O and partitions. The partitions may be able to stay running, or may have to be shut down from the resulting changes. In the invention, multiple copies of the OS are running independently of each other, each in a partition that has its own cell boards with processors and memory and connected I/O. This provides isolation between different applications. Consequently, a fatal error in one partition would not affect the other partitions.

Abstract: The present invention flexibly manages the formation of a partition from a plurality of independently executing cells (discrete hardware entities comprising system resources) in preparation for the instantiation of an operating system instance upon the partition. Specifically, the invention manages configuration activities that occur to transition from having individual cells acting independently, and having cells rendezvous, to having cells become interdependent to continue operations as a partition. The invention manages the partitioning forming process such that no single point of failure disrupts the process. Instead, the invention is implemented as a distributed application wherein individual cells independently execute instructions based upon respective copies of the complex profile (a “map” of the complex configuration). Also, the invention adapts to a degree of delay associated with certain cells becoming ready to join the formation or rendezvous process.

Abstract: The present invention, in various embodiments, provides techniques for allocating resources for efficient use by a program. In one embodiment, a method implementing the techniques comprises the steps of identifying an I/O device connected to a storage device storing data associated with the program, and allocating memory arrays and a processor both of which having a shortest distance to the I/O device. In one embodiment, the resources reside in a plurality of nodes each of which includes one or a combination one or more of an I/O device, memory arrays, and a processor. Further, the resources are grouped in a node if they are on the same system bus or if they are connected to a chip providing point-to-point links to resources. In one embodiment, the relative distance between the resources is stored in a table embedded in firmware portable from one operating system to another operating system.
