Hilda J. Wu is an inventor associated with San Jose, California, and International Business Machines Corporation. Her patent work addresses how virtual storage can improve the efficiency of external sorting.

Latest Patents

Wu is credited with 1 patent: “External Sorting Using Virtual Storage as a Work Device.” The invention uses a real memory-backed, demand-paging virtual store as the work device for an external sort. Compared with using internal memory or direct-access storage devices, this approach can reduce data movement and processing time. It also avoids reblocking partial sort strings during sorting and the fully ordered string during merging. The patent describes an optimal ratio of internal memory backing to virtual storage of 30–80 percent and explains that page faults can be reduced because each data element needs to be referenced only twice.

Career Highlights

Wu’s listed patent reflects work on improving the performance of data-processing operations through virtual-storage techniques. Her association with International Business Machines Corporation connects this invention to the company’s computing and information-processing work.
