摘要： A mechanism is described for managing the caches on nodes in a cluster. The caches are globally managed so that a data item may be retained in any cache on the nodes. This may be accomplished by, for example, a replacement policy for replacing data items stored in the buffers of the caches, where a buffer is selected for replacement in a manner that accounts for factors that include the state of the caches of other nodes. Some cached data items are designated as globally shared, and assigned (either statically or dynamically) a primary cache. For example, if a buffer holds a copy of a data item whose primary cache is another node, then the data item in the buffer is favored for replacement over a local data item or a global data item for which this is the primary cache. According to another aspect of the invention, the cache retention value of buffers on different nodes are compared, and the buffer with the lowest cache retention value is selected for replacement. According to yet another aspect of the present invention, the replacement policy accounts for the configuration of other caches in the cluster.

摘要： An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction through a process controller. The precise location of a sewing machine needle and fabric is illuminated and a color video camera which is mounted on a cross beam holding a sewing machine head is also focused on this location. The color video camera is connected through a preprocessor and a frame grabber to a process controller. A pattern creation means is also connected to the preprocessor and through the frame grabber to the process controller. The process controller includes a Machine Vision - R program which takes the pattern created by the pattern creation means and converts it into a pixel. The pixel is then mapped on a grid to determine the locations where the pattern is to duplicated. The process controller can then cause the pattern to be subsequently repeated at any multiplicity of desired locations.

摘要： A roll to roll machine which incorporates the features of using a video camera and monitor to locate an intersection of a sewing needle and material and create a visual image of this intersection so that a remote operator can create a pattern of thread sewn into the material as the material passes from one or more feed rollers to a pickup roller. The movement of the vertically oriented U-shaped frame which carries the sewing machine head is controlled by one process controller while the sewing and stitching functions of the sewing machine head is controlled by a second process controller.

摘要： An automatic quilting machine for use in stitching individual selected patterns into a large fabric such as a bedspread or quilt. The bedspread or quilt is stretched on a large metal frame which is mounted on a table which can be moved in the X-direction, the Y-direction, or any X-Y combination direction through an automatic joystick. The sewing machine head is mounted on a cross beam which is aligned at the approximate center point of the metal frame on which the fabric is stretched. The needle of the sewing machine head can stitch a pattern into any location in the fabric and the metal frame is moved in any direction relative to the fixed sewing machine head in order to bring the desired stitch location on the fabric into alignment with the sewing machine head. The precise location of the sewing machine needle and fabric is illuminated and a color video camera which is mounted on the cross beam holding the sewing machine head is also focused on this location. The color video camera is connected to a television monitor so that a visual image of the sewing machine needle and fabric as a stitch is being made can be delivered to the monitor. A machine operator can control the movement of the metal frame through positioning by a remote joystick and can see the stitch being made by viewing the monitor.

摘要： Techniques are provided for managing caches in a system with multiple caches that may contain different copies of the same data item. Specifically, techniques are provided for coordinating the write-to-disk operations performed on such data items to ensure that older versions of the data item are not written over newer versions, and to reduce the amount of processing required to recover after a failure. Various approaches are provided in which a master is used to coordinate with the multiple caches to cause a data item to be written to persistent storage. Techniques are also provided for transferring data items and locks associated with the data items from one node to another.

摘要： A method and computer-readable storage representing resources in a cluster by a plurality of attribute-value pairs that together are part of a “resource profile,” in which each attribute-value pair defines all, or a portion of, a management policy that applies to the resource. A clusterware manager configures a resource according to the resource profile, and follows a resource profile syntax that specifies a runtime value for the resource in which an actual value is substituted at runtime.

摘要： A composite resource is established that includes a plurality of members. Each of the members is capable of providing a comparable service. A coordinator monitors a state of each member of the composite resource. A component requests the service from the coordinator. The coordinator arranges for the service to be provided to the component by a particular member of the composite resource. When the particular member ceases to be active, the service is automatically provided to the component by another member in the composite resource. A state of the composite resource is maintained independently of the state of each member in the composite resource.

摘要： Events of interest are detected in order to manage a high availability framework. In a framework in which a plurality of components are executing, the components are periodically polled to detect occurrence of the event of interest. A monitor is also established for one or more of the components. After the first component causes the event of interest to occur, the monitor communicating the event of interest to the framework without waiting for the framework to poll the first component.

摘要： A V-twin engine having a crankcase and a pair of cylinders defining a V-space therebetween, wherein the V-space is substantially enclosed, and a carburetor is positioned within the V-space. An intake air preheating arrangement supplies heated intake air to the carburetor, and a carburetor heating arrangement heats the V-space and the carburetor which is positioned within the V-space. Each of the foregoing arrangements, used separately or in combination within one another, aids in preventing “freeze-up” of the carburetor during running of the engine in a cold environment.
