ALEXANDRIA, Va., Feb. 28 -- International Business Machines, Armonk, N.Y., has been assigned a patent (8,386,822) developed by Ravi K. Arimilli, Austin, Texas, Satya P. Sharma, Austin, Texas, and Randal C. Swanberg, Round Rock, Texas, for a "wake-and-go mechanism with data monitoring."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism recognizes a programming idiom, specialized instruction, operating system call, or application programming interface call that indicates that a thread is waiting for an event. The wake-and-go mechanism updates a wake-and-go array with a target address, expected data value, and comparison type associated with the event. The thread then goes to sleep until the event occurs. The wake-and-go array may be a content addressable memory (CAM). When a transaction appears on the symmetric multiprocessing (SMP) fabric that modifies the value at a target address in the CAM, logic associated with the CAM performs a comparison based on the data value being written, expected data value, and comparison type."
The patent application was filed on Feb. 1, 2008 (12/024,540). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=83,86,822.PN.&OS=PN/83,86,822&RS=PN/83,86,822
