Abstract
This invention provides a computer system architecture and method for providing the same which can include a web page search node including a web page collection. The system and method can also include a web server configured to receive, from a given user via a web browser, a search query including keywords. The node is caused to search pages in its own collection that best match the search query. A search page returner may be provided which is configured to return, to the user, high ranked pages. The node may include a power-efficiency-enhanced processing subsystem, which includes M processors. The M processors are configured to emulate N virtual processors, and they are configured to limit a virtual processor memory access rate at which each of the N virtual processors accesses memory. The memory accessed by each of the N virtual processors may be RAM. In select embodiments, the memory accessed by each of the N virtual processors includes DRAM having a high capacity yet lower power consumption then SRAM.
