Abstract: Systems, methods, and apparatuses relating to instructions to reset software thread runtime property histories in a hardware processor are described. In one embodiment, a hardware processor includes a hardware guide scheduler comprising a plurality of software thread runtime property histories; a decoder to decode a single instruction into a decoded single instruction, the single instruction having a field that identifies a model-specific register; and an execution circuit to execute the decoded single instruction to check that an enable bit of the model-specific register is set, and when the enable bit is set, to reset the plurality of software thread runtime property histories of the hardware guide scheduler.

Abstract: A lock of the type having a plurality of locking bolts, having outer ends extending through openings in the door and inner ends located close to one another inside the door, and having a disc member, with arcuate slots and operating pins extending into the slots, and connecting with the inner ends of the bolts so that rotation of the disc in one direction will cause outward movement of the bolts, and rotation of the disc in the other direction will cause inward movement of the bolts, the lock having an operating lever swingably mounted adjacent the disc, and having one end swingable towards and away from it and connecting means between one end of the operating lever and a point on the disc spaced from its center of rotation, whereby swinging of the lever in one direction will be transmitted to the disc as a rotary movement in one direction, and swinging movement of the lever in the other direction will cause rotation of the disc in the other direction, and having means urging the lever in one direction, the l
