Latest Patents

One of his latest patents is titled "Resource harvesting in scalable, fault tolerant, single system image clusters." This patent presents a method that enhances the survivability of system software components, even in the event of catastrophic failure of the computing element on which they reside. The combination of a distributed operating system (Non Stop Clusters) and a fault-tolerant interconnect (ServerNet) creates an environment conducive to posthumous recovery strategies that were previously unavailable in distributed computing environments. The specific strategy outlined is called resource harvesting, which involves a novel approach to retrieve critical data structures of memory from a failed computing element for reconstruction on a non-failed computing element, allowing these critical data structures to continue with their original function.

Another significant patent by Alexander is "High availability access to input/output devices in a distributed system." This patent describes a system area network computer system architecture structured as a single system image cluster operating system. It offers an opportunity to increase the availability of I/O devices in the system. The computing system comprises several processor units coupled to a plurality of input/output (I/O) elements by a routing fabric, providing each processor element with access to any one of the I/O elements. By utilizing a Transparent Network Computing extension to a highly available version of UNIX System V Release 4.2, the system enhances the availability of I/O devices by allowing for the takeover of their controlling entity.
